About Excel Tools

An Excel (.xlsx) viewer opens and inspects spreadsheets in your browser without needing Excel or Google Sheets. Useful for previewing a file before downloading the full app, sharing with collaborators who don't have Office, or reading legacy workbooks on a fresh machine.

Frequently asked questions

View, with cell selection and copy. Editing in-browser would require uploading; we keep the file local.

Most are — supported functions cover the common 200+ formulas. Workbooks using array formulas, dynamic-array functions, or VBA macros may show static values only.

Convert to .xlsx first; the legacy binary format is too fragile to handle reliably in-browser.
