Open Excel files without Excel
Open a spreadsheet someone sent you, read it as a clean grid, sort it, filter it and edit it. Then save it as Excel or CSV.
Drop a spreadsheet here
or choose one from your computer (.xlsx, .xls, .ods or .csv). Markdown works too.
Your file stays on your computer. Nothing is uploaded.
Opens what you’re sent
Excel (.xlsx, .xls), OpenDocument (.ods) and CSV, every sheet as a tab.
Sort and filter
Sort by any column and filter rows as you type, with the heading row kept in place.
Edit like Excel
Type in a cell or the formula bar, and formulas update as you go. Add or delete rows, add and rename sheets.
Private by design
It all runs in your browser. Your spreadsheet never leaves your computer.

- Is my spreadsheet uploaded anywhere?
- No. Your browser opens and saves the file on your own computer. Nothing is sent to us or anyone else.
