The corrupt .ods generated by loading an xslx file.
I tried to import an xslx file into LibreOffice, and it ended up broken: The first column of data overlap the column of row #s, and their drawing is messed up (whichever one updates last gets drawn).
I saved it out as ods hoping that would fix it, but no luck.
I tried importing the original xslx file back into LibreOffice today, and it actually imported correctly. I couldn't swear I was running 3.5.0 when the import failed the first time, but I was somewhat sure that I grabbed 3.5 on the day it was released, and that I had imported the file using the new version when I received it on the 17th.
In fact I recall being disappointed that the brand new version was failing on the second file I tried. So I can't explain why it works now and didn't work then, unless the first xslx file I imported left Calc in a bad state.
I'm attaching the corrupted .ods file with the data removed. It still loads in a broken manner as described above, even in 3.5.0.
So for me, I don't need any help at the moment, since the file loaded. But I thought you might want to see a corrupt .ods file that stays corrupt even after you load it and resave it.
Please attach that original xlsx file if not private, then mark this bug UNCONFIRMED.
Have you tried latest stable release & resetting user profile?
It's a dup.
Sorry, this was over a year ago. I've since paid the Microsoft tax and purchased a real version of Office, so I am no longer using LibreOffice.
What I did attach was the broken file; it might be useful to have Calc verify the data as it reads it to ensure that Calc itself doesn't get into a bad state.
Unfortunately without the original document there's very little we can do.
Closing as INVALID - Urmas if you happen to know what it's a dupe of feel free to mark it as such.
