Excel Editor Online Free — No Microsoft Office Required
Edit Excel Files Without Office
Microsoft Office costs $69+/year. Google Sheets requires a Google account and uploads your file to Google's servers. FreeFileKit's Excel Editor opens .xlsx files in your browser — no account, no subscription, no upload. Edit cells, rename sheets, and download the modified file.
Formula Support
Common Excel formulas are evaluated in the browser: SUM, AVERAGE, COUNT, IF, VLOOKUP, INDEX/MATCH, CONCATENATE, and date/time functions. Complex array formulas and macros are not supported — for those, LibreOffice or the desktop Excel remain the right tool.
Multi-Sheet Navigation
Tabs at the bottom of the editor let you switch between sheets just like in desktop Excel. You can rename, duplicate, or delete sheets. Cross-sheet formula references (=Sheet2!A1) are supported for reading, though not for live recalculation across sheets.
