  • What are Excel Macros?: A macro is a small program or set of actions that can be run repeatedly. They automate repetitive tasks, saving time and effort.
  • Example Application of Macros: Businesses use macros to manage lists of potential customers and streamline worksheets by hiding unnecessary columns.

Recording and Editing Macros

  • Steps to Record an Excel Macro:
    • Click the "View" tab in the Excel ribbon.
    • Click the "Macros" button.
    • Enter a name for the macro (e.g., Hide_Columns).
    • Choose where to store the macro (e.g., This Workbook).
    • Click "Record Macro" to begin recording actions.
    • Perform the desired actions in Excel (e.g., hide columns).
    • Click "Stop Recording" when finished.
  • Recording Macro Information: The exact commands are recorded and saved in the VBA code.

How to Edit Excel Macros

  • Edit VBA Macros: Macros can be edited by clicking "Edit". The code will visually show the commands from recording.
  • Recorded Actions: The macro code automatically reflects the recorded keystrokes and mouse clicks to perform the intended task.

Automating tasks with Macros

  • Using Developer Tab: Record macros from the Developer tab to automate tasks. The Developer Tab needs to be activated.
  • Using Macros for Automation: Macros can automate excel tasks to save time and effort.

Working with Macro-Enabled Workbooks

  • Macro-Enabled Workbooks: Excel macro-enabled workbooks have the file extension .xlsm.
  • VBA Code: VBA code is used to create macros, which automate functions in excel.
  • Functionality in Macro-Enabled Workbooks: Macro-enabled workbooks are useful to automate tasks such as creating charts and pivot tables with Excel, saving time and effort when working with large datasets or formulas.

Using Excel Functions in VBA Code

  • VBA Functions: VBA has built-in functions, but worksheet functions are better for certain uses within VBA.
  • Worksheet Functions: Excel worksheet functions like VLOOKUP are available in VBA for quick use.

Error Handling in VBA

  • Err.Number: The Err.Number property in VBA can detect if an error has occurred, providing error handling within macros.
  • On Error Resume Next: This statement is used for handling errors within VBA code without terminating the macro.
  • Reset Err.Number: Using On Error GoTo -1 resets the error flag.

Advanced VBA Programming Techniques
