  • Key features include:
    • Grouping data into categories
    • Breaking down data by years and months
    • Filtering data to include or exclude categories
    • Building charts
  • Pivot tables can be built quickly

Pivot Tables Step-by-Step

  • Select the data range, then click Insert > PivotTable
  • In the Create PivotTable dialog, choose where to place the pivot table

  • Each row contains information about a single entity
  • Each column contains the same piece of information for each entity

Understanding a Table’s Structure

  • Header Row:
    • Colored differently to identify columns
    • Contains filter buttons for sorting and filtering
  • Data Body:
    • Rows of data with alternating colors
    • New data automatically inherits formatting, formulas, and data validation
  • Total Row:
    • Not visible by default, but can be shown by checking the Total Row box in the Table Style Options group
    • Each cell in the total row has a drop-down for common functions
  • Resizing Handle:
    • Located at the bottom right of the last cell
    • Drag to change the table size to add or remove rows and columns

Creating a Table

  • From Existing Data:
    • Ensure no completely blank rows or columns
    • Select any cell within the range and choose Insert > Tables > Table (or press Ctrl+T)
  • From Empty Range:
    • Select the range and choose Insert > Tables > Table
    • Excel creates the table with generic column headers and applies table formatting

Adding Data to a Table

  • Without Total Row:
    • Start typing in the row just below the table

    • Insert rows into the table using Home > Cells > Insert
    • Shortcut keys are Ctrl+-(minus sign) and Ctrl+=(plus sign)

Sorting and Filtering Table Data

  • Sorting:
    • Click the filter button in the column header and choose a sort command
    • Sort by multiple columns by sorting the least significant column first and the most significant last
  • Filtering:
    • Click the filter button in the column header and select criteria
    • Entire worksheet rows are hidden, affecting data outside the table
    • Use Text Filters or Number Filters for more complex conditions
    • Right-click a cell and use the Filter command for additional options
    • To remove filtering, click the drop-down in the row header and select Clear Filter

Filtering with Slicers

  • Select any cell in the table
  • Choose Table Design > Tools > Insert Slicer, then check the fields you want to filter
  • Click a button to filter the table; use Ctrl to select multiple buttons, and Shift to select a continuous group of buttons
  • Click the Clear Filter icon to remove filtering

Lookup Functions

  • Used to lookup and retrieve data

VLOOKUP Function

  • Lookup and retrieve data from a specific column in a table
  • Syntax: =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
    • lookup_value: The value to look for in the first column of the table
    • table_array: The table from which to retrieve a value
    • col_index_num: The column in the table from which to retrieve a value
    • range_lookup: [optional] TRUE = approximate match (default), FALSE = exact match

HLOOKUP Function

  • Lookup and retrieve data from a specific row in a table
  • Syntax: =HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
    • lookup_value: The value to look for in the first row of the table
    • table_array: The table from which to retrieve a value
    • row_index_num: The row in the table from which to retrieve a value
    • range_lookup: [optional] TRUE = approximate match (default), FALSE = exact match

XLOOKUP Function

  • A modern and flexible replacement for VLOOKUP and HLOOKUP
  • Syntax: =XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])
    • lookup_value: The value to search for
    • lookup_array: The array to search within

Boolean Logic

  • Formal description for the idea of TRUE and FALSE
  • Rooted in binary logic, where TRUE is synonymous with 1 and FALSE equates to 0

Logical Operators in Excel

  • Equal to (=)
    • Formula: =A1=B1
