Reducing File Size

James complained about an oddity that he noted with his workbooks. He has a workbook to which he added some macros, and doing so increased the size of the file used to store the workbook. (This makes sense—the macros are stored with the workbook.) When James later deleted the macros, Excel did not shrink the size of the workbook file back to its original size.

This behavior is viewed by some as poor design in Excel—the macro data is removed, but the file size remains bloated. There are a couple of things you can try to again regain your svelte file size.

First, try using Save As instead of Save. Doing so causes Excel to create a brand new file for your workbook, and in the process, free up some space. If that doesn't work, you should try individually copying your worksheets to a brand new workbook, and then saving the new workbook. If doing that doesn't work, then you can try copying just the worksheet data (not the actual worksheets) to a different workbook. Obviously, this can become quite time-intensive.

Another option to try is saving the workbook in the .xlsb format. This could reduce the file size by about a third. This format is okay if the file isn't accessed by other programs You could also look for any unused rows and columns at the end of the worksheet. In each worksheet press CTRL+END to go to what Excel thinks is the last cell in the worksheet. If the last cell is in an unused area of the worksheet, then the unnecessary rows colums can be deleted. One reader suggested saving the workbook in .htm or .html format and then resaving it back to .xlsx. This removes any left-over VBA that could cause the file to bloat.

Another thing to try, provided you still have some macros in the workbook, is a free utility called CodeCleaner, written by Excel MVP Rob Bovey. You can find the program on this page:

The tried-and-true method I've used for decades to reduce Excel file size is to select cell A1 on every worksheet, then save the file (SaveAs not needed).
