Total Recalc: watch an AI agent edit an Excel model
A free, open-source desktop viewer that reloads an Excel workbook when an AI agent saves it, so you can follow the changes without opening the file for editing.
- For
- People reviewing AI-edited Excel models
- Worth noticing
- Its change panel separates direct edits from formula recalculations; the interactive replay uses sample data, and macOS is listed as untested.
Field notes
The desktop app reads an Excel workbook into memory and releases the file, so an agent can save over it; an incomplete save leaves the last good version on screen. It preserves the current sheet, scroll position, and selection across saves, while its change panel groups direct edits separately from recalculated results and matches rows by labels. The page offers Windows and Linux installers; the macOS build is explicitly marked untested. The project identifies itself as free, open source, and MIT-licensed.
