How do I duplicate an Excel workbook?

You can duplicate an Excel workbook by copying the contents of the existing workbook into a new one. Here's how:

1. Open the workbook you wish to duplicate.

2. Select all cells within the worksheet. The quickest way to do this is by pressing Ctrl+A (Windows) or Command+A (Mac). Alternatively, you can click the small triangle at the top-left corner where the row and column headers meet.

3. Copy the selected cells. Press Ctrl+C (Windows) or Command+C (Mac) to copy the contents to your clipboard.

4. Create a new, blank workbook. Go to the "File" tab and select "New," then choose "Blank workbook."

5. Select cell A1 in the new workbook.

6. Paste the copied cells. Press Ctrl+V (Windows) or Command+V (Mac) to paste the contents from the clipboard into the new workbook. This will effectively duplicate the contents of your original worksheet.

This method effectively copies the data and basic formatting. However, note that more complex features like macros, data connections, and some advanced formatting might require additional steps or adjustments. For instance, if your original workbook has VBA code (macros), you'll need to copy the module containing the code into the new workbook's VBA project.
