Project #3: Inserting the Headers

 Before diving into data cleaning and formatting, let's start by ensuring our Excel worksheet has headers. Headers provide descriptive labels for each column, which makes the data easier to understand and work with. We'll create a macro to insert headers in the first row of the active worksheet.

Here's how to create the macro:

Start the Macro Recorder: Go to the Developer tab, click on "Record Macro," and give your macro a name (e.g., "InsertHeaders"). Optionally, assign it to a shortcut key. Make sure to store it in the current workbook.

Insert Headers: With the Macro Recorder running, insert headers in the first row of the active worksheet. You can manually type in the header names or copy them from another source.

Stop Recording: Once you've inserted the headers, go back to the Developer tab and click on "Stop Recording."

Review Recorded Macro: Open the Visual Basic Editor (Alt + F11) and navigate to the module where the macro was saved. You'll see the VBA code generated by the Macro Recorder.

Modify the Code (Optional): Review the recorded code and make any necessary modifications. For example, you may want to add comments or error handling.

Here's an example of what the VBA code might look like:

Sub InsertHeaders() 
' Insert headers in the first row of the active worksheet
    ActiveSheet.Range("A1").Value = "Header 1" 
ActiveSheet.Range("B1").Value = "Header 2" 
ActiveSheet.Range("C1").Value = "Header 3" 
' Add more lines for additional headers as needed 
End Sub

In this example, we're inserting three headers ("Header 1", "Header 2", "Header 3") in columns A, B, and C of the active worksheet. You can modify the code to insert the headers you need and adjust the column references accordingly.

Once you've created and tested the macro, you can run it whenever you need to insert headers in a worksheet. Having descriptive headers will make it easier to work with the data and perform subsequent data cleaning and formatting tasks.
