Questions about Gridora
Can I open and edit Excel files?
Yes. Gridora opens .xlsx, .xls and .xlsb files and saves back to .xlsx with formulas, styles, merges, rules and comments.
Does it work with Google Sheets or LibreOffice?
Yes — export to OpenDocument (.ods) or CSV and open the file in either.
Do my formulas still work after export?
Formulas are kept in .xlsx, .ods and the XML formats. A few older or simpler formats (like Apple Numbers and CSV) save the results only.
Is Gridora free?
Yes. The Free plan includes every feature within the workbook and size limits above.
