3 CHAPTER Advanced Features of Writer As we all know that LibreOffice Writer is a word processor that provides a variety of features. You have already learned some of the features, such as formatting, editing, inserting tables and images, styling the text and inserting graphics in the document. In this chapter, you will be learning some advanced features of LibreOffice Writer that will be used to create professional documents. To give the listing of the contents of the document, we can use the Table of Contents feature, which is based on different types of heading styles. LibreOffice Writer also provides templates to create professional documents. When multiple users are working on a single document, the Track Changes feature can be used to keep a track of the editing being done by each user. Table of Contents In Class IX, you had learned to insert tables in a document, where the data was represented in a row and column format. In this chapter, we will discuss Table of Contents (ToC). You must have seen table of contents in the beginning of your books. It contains a list of topics and subtopics that have been covered in the book along with page numbers. Table of Contents, allows to insert an automated table of contents in a document. The entries or contents of this table are automatically taken from the headings and sub headings of the document. Also, these contents are hyperlinked in the table. So by clicking on any topic in the table of contents, we can navigate directly to the selected topic. But before creating table of contents, you need to first understand the concept of hierarchy of headings. 2023-24  Hierarchy of Headings LibreOffice Writer supports up to 10 levels of headings H1 to H10. These headings are applied to the headings of the document. The following process will demonstrate how to apply these headings to the headings in the document. Step 1. Create a new document in LibreOffice Writer and enter the text Heading 1 to Heading 10 as shown in Fig. 3.1. Step 2. Click on the Styles button from the right side bar. Click on the Paragraph Styles and then Headings. The Styles dialog window will display the list of headings from Heading 1 to Heading 10 as shown in Fig. 3.1. Step 3. Place the cursor on Heading 1 as typed in the document. Fig. 3.1: Hierarchy of 10 Headings Then click on the Heading 1 from the Styles dialog window. Step 4. Repeat Step 2 for the words Heading 2 to Heading 10. Step 4. Observe that Heading 1 to Heading 10 is applied to the words Heading 1 to Heading 10 of the document and these headings have changed as per the applied style as shown in Fig. 3.2. Observe the change in Figs. 3.1 and 3.2. Once the desired heading styles are applied in the document, the same Fig. 3.2: Document after applying 10 Headings hierarchy will be reflected in the table of contents also. Creating a Table of Contents (ToC) Before you start creating the table of contents or ToC in a document, you must ensure that proper heading styles, such as Heading 1, Heading 2, Heading 3 and so on are inserted in the document. The correct ToC will be 48 Domestic Data entry operator – class X 2023-24 generated only if proper paragraph styling for headings is applied to the document. Once a styled document is created, follow the steps given below to insert the ToC in the given document: Step 1. Open the earlier created file “documentation.odt”. Step 2. Assign proper heading styles to the various headings in the document from the Styles dialog box. For example, assign the heading styles as shown in Fig. 3.3 in the “documentation. odt” file. Step 3. Place the cursor at Fig. 3.3: Planning for assigning headings styles the position where the table of contents is to be inserted. Usually, it is in the beginning of the document. Step 4. From main menu, select Insert > Table of Contents and Index > Table of Contents, Index or Bibliography. The Table of Contents, Index and Fig. 3.4: Table of Contents, Index or Bibliography dialog box Bibliography dialog box will be displayed as shown in Fig. 3.4. Step 5. By default, the Type tab will be selected with a preview of ToC on the right side of the dialog box. On the left of the dialog box, is the Types and Title section. In the Title text box, the default name of the ToC, i.e. Table of Contents is displayed. You can change this name, just by typing in the text box. Type the desired title of the ToC say “Contents” in the Title text box. The title will be changed in the Preview section as shown in Fig. 3.4. Digital Documentation (aDvanceD) using libreoffice Writer 49 2023-24  By default, the checkbox for Protected against Manual Changes option is selected. This protects the ToC from any accidental change. If this box is unchecked, then the contents of ToC can be changed directly on the document page, just like any other text on the document. In the Create Index or Table of Contents List box, the Entire Document Fig. 3.5: Table of Contents inserted in a document option is selected in the For list box. So the ToC will be automatically created from the headings and sub-headings of entire document. The Outline check box is selected, so the complete outline of the ToC is shown in the preview. Click and deselect it if you do not want to see it. Step 5. Click OK button. The Table of Contents will be inserted in the document as shown in Fig. 3.5. Note that all the headings will appear with page numbers in the ToC. The entries in the ToC are hyperlinked. Moving a mouse pointer over any of the entries will show a tool tip stating to press Ctrl+click to open hyperlink followed by the heading title. Pressing Ctrl+click the cursor will directly move on to the selected section heading. Practical Activity 3.1 Rimjhim has created a report on Environmental Pollution in LibreOffice Writer. She has applied proper heading styles to all section headings of the document. Now, to add table of contents to the document with the heading as Rimjhim’s Table of Contents, follow the steps given below. Step 1. Open the document in LibreOffice Writer. Step 2. Select Insert > Table of Contents and Index > Table of Contents, Index or Bibliography. The Table of Contents, Index and Bibliography dialog box will be displayed. 50 Domestic Data entry operator – class X 2023-24  Step 3. In the Type the Titles text box, type Rimjhim’s Table of Contents. Step 4. Click OK. The Table of Contents will be inserted in Rimjhim’s document. Customisation of ToC Once the ToC is inserted, we can customise it according to our requirements. To do so, right click anywhere on the ToC and select Edit Index option from the popup menu as shown in Fig. 3.6. The Table of Contents, Index or Bibliography dialog box will be displayed as shown in Fig. 3.7. As seen in the previous section, the dialog box has five tabs – Type, Entries, Styles, Columns and Background. The options in these tabs can be used to edit the table in various ways. The changes made will be reflected in the Preview section of the dialog box. Fig. 3.6: Selecting Edit Index option from the pop up menu Fig. 3.7: Selecting Entries Tab in Table of Contents, Index or Bibliography dialog window Digital Documentation (aDvanceD) using libreoffice Writer 51 2023-24  Type Tab: is active by default after opening the Table of Contents, Entries or Bibliography dialog box to insert the ToC.

To remove the Fig. 3.9: ToC with changed background color background colour from the ToC, click None button present on the top of the dialog box. LibreOffice Writer also allows to add a graphic as a background of the ToC. For this, select the Bitmap button in the Background tab of the dialog box. Select the desired graphic option and click OK button Fig. 3.10: Adding graphic as a background of the ToC (Fig. 3.10). Maintaining a Table of Contents As we know now that a table of contents is a snapshot of the entire document at any given point in time. If any changes are made to the document section headings or page numbering, it should be reflected in the Table of Contents as well. Maintaining a Table of Contents consists of updating and deleting the ToC. Digital Documentation (aDvanceD) using libreoffice Writer 53 2023-24  notes Updating the ToC Writer does not update the ToC automatically. The following activity shows how to update a ToC manually. Practical Activity 3.2 Some more sections are added in the document, accordingly the ToC needs to be changed. To update a ToC manually, follow the steps given below. Step 1. Right-click anywhere in the ToC. Step 2. From the pop-up menu as shown in Fig. 3.11, select Update Index option. Writer updates the ToC so as to reflect any changes made in the document. The reflected changes in ToC is shown in Fig. 3.12. Fig. 3.11: Selecting options for updating and editing a ToC Fig. 3.12: Updated ToC 54 Domestic Data entry operator – class X 2023-24 Deleting ToC notes To delete the ToC, right click on the table and select Delete Index option from the pop-up menu.

Click the Color button on the top of the dialog box. Step 5. Select the desired color from the Colors palette. The selected color will appear in the New color window. Step 6. Click OK to apply the desired color to the ToC. Using Templates A template is a preset layout that helps to create professional and/or formal documents easily. In the previous chapters, we have learned styling of different document objects using templates. In this section, we will learn to create document templates. Sometimes there is a need to copy specific content including graphics, such as logo of a company, image of a product or text, such as tag lines of a product or a company, legal notices or even headers and footers in multiple documents. Instead of adding and then formatting the objects in all documents, we can use templates. For example, templates can be used to create a resume, chapter or project report. A template can contain all the features or objects that a regular document can contain – text, graphics, styles and can even use any language. In a template we can create and save defined headings, text formats, styles, page numbers, headers and footers. Digital Documentation (aDvanceD) using libreoffice Writer 55 2023-24  When new documents are created from these templates, they have the same content segregation, formatting features and appearance as that of the applied templates. At the same time, Writer also allows us to edit the styles and contents of the document to which the template is applied. All documents in Writer are based upon templates. If no specific template is specified, then Writer uses the default template as blank document template for the file being created. Checking the template of the document To see what template is associated with a document, select Properties option from the File menu. The Properties dialog box will be displayed as shown in Fig. 3.13. Since the document was created from the default template, no template is listed in Fig. 3.13. Fig. 3.13: Document properties with no template 56 Domestic Data entry operator – class X 2023-24  When the document is created with template, this window will display the name of the template. For example, if you want to create a document with template. Follow the steps given below. Step 1. Create a new document from File > New > Templates … Step 2. A template selection window will be displayed as shown in Fig. 3.14. Select a template, for example, select the first template ‘Modern business letter’. Fig. 3.14: Selecting a template Step 3. Click on Open button, a document with the selected template will open as shown in Fig. 3.15. Step 4. Now check the template of the created document from File > Properties.

Track Changes Feature Track Changes is a powerful tool that makes the process of commenting, editing and reviewing of a document easy between multiple users. A document created by one user need to be reviewed and edited by self or other users. If any modifications are made in the document directly, the original document might get lost. Instead, the Track Changes feature of Writer offers an alternative method to keep a record of all the changes made in the original document. All the changes that are recorded can be either accepted or rejected by the original author.

Every profession, household, institution and even our smart devices have to deal with numbers. In computers we can do the calculations on number of records spread over the long sheet using the spreadsheet software that helps to work with numbers efficiently. It resembles an accountant’s ledger book wherein everything is recorded under suitable headings. We have already learned in Class 9, that how the spreadsheet software performs calculations and present data in tabular format. It becomes easy to visualise a huge grid of numbers when represented using charts in electronic spreadsheet. Moving further, in this unit you will learn advanced features of electronic spreadsheet using LibreOffice Calc to perform analysis, automate repeated tasks, link, share and review data. It includes – analysing data to extract useful information for making effective decisions. Macros, is the another powerful feature of spreadsheet covered in this unit. Macros are a set of stored functions used to automate processes repeatedly. They are tools which can be used 2023-24 to perform most of the redundant tasks with relative notes ease. In the second chapter of this unit, you will learn to create multiple sheets and link the data in multiple sheets. It can be done in two ways, one is creating reference to other sheets by using keyboard and mouse, and other is by linking external data. LibreOffice Calc also provides the sharing feature that allows to share the spreadsheet for editing purpose. This saves to keep track of multiple copies of the same spreadsheet corrected by different users. Sharing allows the users to work on the same spreadsheet in collaboration. ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 85 2023-24  Analyse Data using 4 CHAPTER Scenarios and Goal Seek IntroductIon Analysing data is the process to extract useful information for making effective decisions. The spreadsheet is one of the best software used for data analysis. It is used to retrieve, correlate, explore and visualise data to identify patterns, trends and relationships. The spreadsheet component in LibreOffice known as Calc includes several tools used to manipulate the data in the spreadsheet. You can analyse the data and interpret the results from it. In this chapter, you will learn to analyse data using LibreOffice Calc. Consolidating Data Consolidate is a function used to combine information from multiple sheets of the spreadsheet into one place to summarize the information. It is used to view and compare variety of data in a single spreadsheet for identifying trends and relationships. You need to check the following before consolidating data. Open each sheet in the spreadsheet and check that the data types must match which you want to consolidate. Match the labels from all the sheets which are used for consolidating. Enter the first column as the primary column on the basis of which the data is to be consolidated. Steps to consolidate the data are as follows: Step 1. Open the spreadsheet which has the data to be consolidated. Step 2. Create a new sheet where the data has to be consolidated. Step 3. Choose Data > Consolidate option that will open Consolidate dialog as shown in Fig. 4.1. 2023-24 Step 4. Observe that the default function “Sum” is seen in the Function drop- down. You will be able to see the list of functions as shown in the Fig. 4.2 by clicking on the Function drop-down. Step 5. Choose the required function from the drop-down list. Step 6. The sources data range list contains existing named ranges to quickly select from that. But if the source range is undefined, then click and select the range from the sheet Fig. 4.1: Consolidate dialog box which is to be consolidated. Step 7. Click on Add to add this range under the ‘Consolidation ranges’ of the Consolidation dialog. Step 8. Repeat steps 6 and 7 to add more sheets to be consolidated. Step 9. Remember to check the target range specified under Use ‘Copy results to’. If it is not mentioned, then click on the cell of sheet where the final data has to be produced. Step 10.Click on Options that will list two checkbox under Consolidate by Fig. 4.2: Functions under consolidate “Row labels” and “Column labels” and “Link to source data” under Options, as shown in Fig. 4.3. From this you can select the additional feature as per requirement. The option consolidate by rows and columns are checked to consolidate data as per row labels and column label. Link to source data is checked to make the modification automatically in the consolidated (target) sheet while making any changes in the source data. Step 11.Finally click on OK button. Let us illustrate this through following Fig. 4.3: Consolidate options activity. ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 87 2023-24  notes Practical Activity 4.1 Let us take an example that we have two branches of our shop namely ABC and XYZ. We have the Sales records for the month of January and February of both the branches in two different sheets named ABC_Branch and XYZ_Branch. Now we have to consolidate these two sheets to get the sum of both the sheets monthly to get the insight about the sale as per product and branch. Now let us create the following sheets in a spreadsheet sales. Fig. 4.4: Data for ABC_Branch Fig. 4.5: Data for XYZ_Branch Now let us use the two sheets ‘ABC_Branch’ and ‘XYZ_Branch’ of a spreadsheet sales.ods which will be consolidated using the following steps: Step 1. Add a new sheet and rename it as Consolidate Step 2. Click on Data > Consolidate or use the keyboard shortcut key ALT+D, the Consolidate dialog window will open as shown in Fig. 4.6. Fig. 4.6: Consolidate dialog window Step 3. In the Function box, choose Sum function from the drop down as we want to add the data from all the sheets. Step 4. Click in the Source data ranges box and then click on the worksheet ABC_Branch and select the area to be consolidated and then click on the Add button will add the copy reference in the consolidation ranges (Fig. 4.7). 88 Domestic Data entry operator – class X 2023-24  notes Fig. 4.7: Selecting the source data range from the sheet Step 5. Click on the sheet XYZ_Branch and select the area to be consolidated and then click on ADD will add the next consolidation range (Fig. 4.8). Step 6. Click on the ‘+’ sign next to Options in the Consolidate dialog window to change the settings. ‘Consolidate by’ has two options Row labels and Column labels. Check row label or column label or both if you want to consolidate it by matching the label. If Link to source data is checked, then it will keep on updating the data of the Consolidate sheet automatically if there is any change made in the selected ranges. Fig. 4.8: Options for setting more properties Step 7. Click on ‘Copy results to’ and then click on any of the cell in the Consolidate sheet where you want to copy the final result after consolidation. Step 8. Click on OK button.

ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 89 2023-24  notes The consolidated sheet will have all the consolidated data along with the original data. You can view the original data of both the sheets and by clicking on the ‘+’ sign in front of the consolidated row. Fig. 4.10 shows the original data and consolidated data. Fig. 4.10: Consolidated sheet details by clicking on the + sign in front of rows Practical Activity 4.2 Create two sheets Marks_Term1 and Marks_Term2 to store the marks in Term1 and Term2 for a set of students taking the following columns: 1. Name 2. Marks in English 3. Marks in Hindi 4. Marks in Maths 5. Marks in Science 6. Marks in Social Science 7. Total marks (using function Sum) 8. Percentage (using function Average) Now, use the consolidate function to merge these two sheets. Groups and Subtotals Group and Outline in Calc is used to create an outline of the selected data and can group rows and columns together so that one can collapse (-) to hide it or expand (+) it using a single click on it. Select the data to be grouped, click on Data>Group and Outline. Then choose Rows to group the data on the basis of rows or columns to group it on the basis of columns. 90 Domestic Data entry operator – class X 2023-24  The Subtotal tool in Calc creates the group automatically and applies common functions like sum, average on the grouped data. One can use any type of summary function for each column as per the requirement of data analysis. It can group subtotals by using category and sorts them in ascending or descending order so that one need not to use filters. Follow the following steps to apply Subtotal tool. Step 1. The sheet where this is to be applied must have labels to the Fig. 4.11: Choosing subtotal option from column Data menu Step 2. Click on Data menu and choose Subtotals (Data>Subtotals) as shown in Fig. 4.11. Step 3. Choose the column in the Group by list in the subtotal dialog which is to be used for grouping the data in the sheet as shown in Fig. 4.12. Step 4. Select the column by clicking the checkbox under Calculate subtotals for to create subtotals for. Fig.4.12: Choose the column in the Step 5. Select the desired function by Group by list clicking the function under Use function. Step 6. You can use the 2nd Group and 3rd Group tabs to group the data in further levels. Step 7. Click on OK button. Practical Activity 4.3 Let us take an example to store marks in various subjects by students of Class X as shown in the table given in Fig. 4.13. To take out the average of the subjects scored in each class, use the subtotal tool which automatically group the data on a particular column and perform the selected function on any of the column. ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 91 2023-24  notes To solve this, perform the following steps: Step 1. Create a sheet as shown in the Fig. 4.13 to take the marks for students in a term for a class. Fig. 4.13: Spreadsheet with student marks in two class Step 2. Now, to calculate the average marks scored by the students of each class in each subject, i.e. class-wise and subject analysis. Step 3. To do so, click on Data > Subtotal, the subtotal dialog as shown in Fig. 4.14 will open. Fig. 4.14: Subtotal dialog window Step 4. Choose the column i.e. Class under Group by in the 1st Group on which we need to group the whole data. Also, select the subjects i.e. English, Hindi, Maths, Science and Social Science under Calculate subtotals for. For each subject click on the Average under Use function individually otherwise Sum function will be used by default. Step 5. Click OK and the sheet will look like as shown in the Fig. 4.15. Fig. 4.15: Marks list after Subtotal 92 Domestic Data entry operator – class X 2023-24 Observe that outline to the left of the row numbers notes which is inserted after performing the subtotal tool. This outline shows the hierarchical structure which can be used to show or hide different levels by clicking on the group indicators ‘+’ sign to expand and ‘–’ sign to collapse the data. You can hide the low-level details and just look at the final totals and grand totals. If you want to remove the outline feature from the sheet at any point of time then it is possible by just clicking on Data > Group and Outline > Remove Outline. Practical Activity 4.4 Create a sheet as shown in Fig. 4.16 and then calculate the average of marks subject wise on the basis of class and stream. Also, try out another function Count to calculate the number of students in each subject. Fig. 4.16: Marksheet What-if Scenarios What-if scenario is a set of values that can be used within the calculations in the spreadsheet. A name is given to the scenario and several scenarios can be created on the same sheet. It is used to explore and compare various alternatives depending on changing conditions. It can be used in the beginning of any project to optimise the output. This tool is used to predict the output while changing the inputs which reflects the output and thus one can choose the best plan of action based on it. ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 93 2023-24  For example, a person who is taking car loan has to decide on certain factors as given below: The number of years for which the car loan is taken. The total amount of car loan The above two factors, i.e. Principal amount and Number of years can display the EMI to be paid monthly. Follow the following steps to create scenario.

Place the cursor on the Variable cell box and Fig. 4.27: Goal seek click on the cell that contains the value to be dialog window changed. Step 6. Enter the desired result in the Target value box. Step 7. Click on OK button. Practical Activity 4.9 Let us take a very simple example to perform the backward calculation to find out an input depending upon the specific output. A student has received marks in 4 subjects and has to appear for the 5th subject and plans an aggregate as 70. So, he can use goal seek tool to check how many marks he has to score in the 5th subject to get the required percentage. Follow the following steps to perform this task. Step 1. Create the marksheet as shown below in the Fig. 4.28. Enter the average function in cell B7 as = Average(B2:B6) Fig. 4.28: Marksheet ElEctronic SprEadShEEt (advancEd) uSing librEofficE calc 99 2023-24  notes Step 2. Click on Tools > Goal Seek will display the Goal seek dialog window as shown in Fig. 4.29. Fig. 4.29: Goal seek dialog window Step 4. Write the cell address of the formula, i.e. B7 in the Formula cell box. Step 5. Write the cell address of the cell which is to be generated by the system in the Variable cell box. In this example, it is cell B6 which we want to be filled as per the average marks needed. Step 6. Enter the result in the Target value box. As per our question, we have to get minimum 70 aggregate so we will write 70 in the target value. Step 7. Clicking on OK will display an error as LibreOffice Calc will not accept the Variable cell to be empty. So, this error dialog window will prompt to add 0 value in the variable cell as shown in Fig. 4.30. Fig. 4.30: Goal Seek failed alert Step 8. Click on Yes and then repeat the step 2 will display the dialog window and prompts whether to change the cell with the calculated value as shown in Fig. 4.31. Fig. 4.31: Goal Seek succeeded Step 9. Click on Yes will change the value with the calculated one in the sheet as shown in the Fig. 4.32.
