How it compares

Compared to Google Sheets, Freesheet is lighter weight and doesn't require a Google account. It's not designed for heavy analytics or multi-user collaboration — for those, Sheets or Excel are better. For everyday "I need to add up some numbers" work, Freesheet is faster.

Privacy

Spreadsheet data stays in your browser. Export to CSV or XLSX to save externally.
