Open an Excel workbook

View your sheets, edit cells, and save your workbook from one workspace.

Choose or drop an .xlsx file up to 128 MiB. Workbook contents stay on this device.

Explore your workbook
Use Files and sheet tabs to move between worksheets. The ribbon and formula bar keep cell commands close to your data.
Edit and save
Make supported cell edits, then use Save to update your workbook or Save as to create a separate copy.
Formula results
Imported formula results are retained until you edit a cell. Supported formulas then recalculate locally; calculation coverage is partial.
