File Size Excel

[Nine Zero]

To All,

I have a .xlsx file which is currently 199KB

I found there was a formula in one of the sheets that was incorrect, so i fixed it and now when i save it grows to 13.5MB.......

The formula is not super complex, it is a simple SUM()....

What could be the issue?

EDIT:
It only happens if i choose to Update External Links...... which there are none of!!! anywhere!!!!!!!!!

If you even have the option to update external links, there is definitely at least one somewhere. (Otherwise the dialog is disabled.) You just haven't been able to find them yet...
