Excel records what changed.
ExcelRewind records why.
Record every cell change with optional voice narration, share a tiny
.rewind file, and replay it anywhere — even inside Excel itself.
Illustrative — the viewer replays real cells, not pixels.
Why not just record a video?
A screen recording shows pixels. A .rewind keeps the actual spreadsheet.

How it works
Three steps, no workbook ever touched.
Record
The add-in captures cell changes, formulas, notes and voice while you work.
Save
Everything packs into a small .rewind file; your workbook is never modified or uploaded.
Replay
Anyone replays it free in the browser viewer, or natively inside Excel with time-synced charts and formatting.
Your spreadsheet never leaves your machine
Sessions record changes, not the file. ExcelRewind is local-first: the
.rewind companion is built and saved on your device, and your workbook is
never uploaded. Read the full privacy policy.
Pricing
Start free. Upgrade when you need more.
Frequently asked
The three things everyone asks first.
Is my spreadsheet data uploaded anywhere?
No. ExcelRewind is local-first — the .rewind file is built and saved on your own device. Your workbook is never sent to a server.
Does it change or modify my workbook?
Never. The .rewind file is a separate companion. Your original .xlsx is left exactly as it is.
What do the people I share with need to install?
Nothing. Recipients open the free web viewer in any browser — no add-in, no account, no download required.
