I've got a (relatively) big Excel file, coming in at around 11.5 MB.
This is a file I inherited and improved upon, adding many tabs, conditional formatting and raw data.
When I got it, the file was around 400 KB. This was about a year and a half ago.
I've got versions of that file going back all the way (every time I made a significant change I saved an older version in a folder), and I figured out the file increased in about 6 MB during February of last year.
I'm looking at both files, and can't seem to see what is it that made the difference. No new tabs were added, not a significant amount of data, nothing.
Is there a way to figure out how much storage space each tab in both excel files takes up so I can locate the mysterious increase in size?
