Why work in your browser

The same jobs, without the upload, the sign-up or the wait.

Your data stays put

Files are read and written in this tab. Nothing is sent to a server, so there is no upload limit and nothing to delete afterwards.

No formulas or macros

Jobs that need a helper column, a VBA macro or a careful copy-paste-values step become a drop, a click and a download.

Works offline

Once a tool page has loaded, it keeps working with no connection at all — handy on a locked-down machine or a plane.

There is no server to send your spreadsheet to

Every tool reads your workbook straight from disk using the open-source ExcelJS and SheetJS libraries, does its work in this tab, and hands the result back as a download. No account, no upload limit, and no copy of your data anywhere but your own machine.
