downloaded a spreadsheet and it says it is corrupted and I can’t open it. Libre calc tries to fix it but doesn’t work either. What can I do?
Never had this problem before.
Data includes lots of personal addresses so can’t share here.
Thanks!
XLSL File: How to open XLSL file (and what it is)
Open xlsl file
From last link:
Files with xlsl extension are almost always Microsoft Excel spreadsheets that have been locked (encrypted) by the Document Manager software from WonderFox.
OK, how do I encrypt it? or is this possible?
Or if I download microsoft excel would that fix this?
You’d wish to decrypt, if it is already encrypted.
