Numbers-file getting slow / crashing with "quit unexpectedly" error
I have a file of + 50 000 rows & 8 columns, and one column uses LEFT-function to parce a string from another column for categorizing data, and I also calculate COUNTA and SUM for two columns.
I have "Categories" for 3 columns active at all times, I also use "Sort" for 3 columns quite often. Some basic formatting in the sheet too. I use manual "Save" after couple new added rows. I also manually copy the file to keep backups quite often.
File is stored in iCould. File size about 20MB.
I run this on mid 2015 MBP with Monterey and 16GB memory, current Number s v 12.2.1
I found out that when I copy all the content ( + 50k rows) CMD-C + CMD-V to a new Numbers file, the file works very quickly at first and does not crash at all. Also saving is done immediately for such a big sheet file.
However, the file gets slower and slower as I use it and "weeks go by". Saving starts to take "seconds" and this "quit unexpectedly" crash starts to happen more often.
Is there another way to "reboot" / "reset" the file than to copy-paste content to a fresh new file? Is there a cache that I can manually delete, as Numbers definitely seems to accumulate log-data for this sheet-file somewhere over time?
