Open and edit XLSX files for free without Excel

Last updated 2026-11-10

How to edit values and formulas in an XLSX file and save it back as XLSX on a computer without Microsoft Excel, with nothing to install.

If you only need to change a few numbers in an Excel file you received but don’t have Excel, or your license has expired, you can make simple edits with just a browser.

How to do it with DocDori

  1. Open the XLSX file in the Workspace. The file is not uploaded to a server.
  2. Select a cell and edit its value or formula. Supported functions are calculated immediately.
  3. You can change bold, font color, fill color, alignment, borders and number format (comma, currency, percentage, date) cell by cell.
  4. Press ‘Download edited copy’ to download a new XLSX file while the original stays untouched. If you only edited cells, the original file structure is kept as is.

Frequently asked questions

The cell formatting looks different from the original. Column widths, row heights, cell formatting, merges and conditional formatting are displayed as in the original. Charts are not displayed, so the area where a chart was will look empty.

Does saving change the original file? No. The edited copy is always downloaded as a new XLSX file.

Do I edit CSV files the same way? You can open and edit CSV files too, and leading zeros and EUC-KR files (the older Korean encoding) are preserved. See Garbled Korean text in CSV.
