This time, every year, I really really want the ability to run a diff of two #LibreOffice spreadsheets.
(And, no, retroactively applying the track changes feature is not that, even though it seems like it is (at least not for spreadsheets. For my task-at-hand, it's actually faster to just put the spreadsheets up on two screens and go line-by-line than it is to take two versions & try the track changes)
@johns Oh, that's a thought. I think it might take me longer than the two-screen-compare-each-number solution because each file has 5-7 tabs, but I suppose I could write a script that exports each tab as CSV and generates the diffs. I should look into that.
