Description ffs 2020-10-05 12:23:50 UTC
Description:
I'm working with relatively large spreadsheets (100 cols x 2000 rows).

Over time with lots of small changes LO gets slower and slower and slower such that this morning changing one cell froze LO for >1min and I killed it and started again.

Associated with this it sharing the file via xlsx format means that excel can no longer read the data (it appears corrupt) but LO works fine.

I find that saving as csv, quitting LO and loading the csv then saving as xlsx usually fixes both problems but this morning nothing let excel load the spreadsheet.

 

Steps to Reproduce:
I can't guarantee any method to reproduce it but I associate it with:

Large spreadsheets
Lots of incremental saves

Actual Results:
LO gets unusably slow
sometimes the xlsx file cannot be read by excel (but saving to other formats works for excel)

Expected Results:
It shouldn't get slow - the data isn't that big
Export to xlsx should always be readable by excel


Reproducible: Sometimes


User Profile Reset: No

One thing to test, it's verify if there are direct formats out of the working space, or a lot of conditional formats. LibreOffice don't like them, and even on the working space if you can avoid it and use styles, maybe can help.
Also use the navigator to search for unexpected objects.

Thank you for reporting the bug.
it seems you're using an old version of LibreOffice.
Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.
