In Excel: open Excel and check File ▸ Info ▸ Manage Workbook ▸ Recover Unsaved Workbooks, then save any recovered copy immediately under a normal file name.
Reopen Excel before creating many new temporary workbooks.
Go to File ▸ Info ▸ Manage Workbook ▸ Recover Unsaved Workbooks.
Open the newest relevant file and verify the contents.
Use Save As immediately, then enable AutoSave or shorten the AutoRecover interval.
What this does
Excel recovery depends on AutoRecover and whether Excel had time to save a temporary copy. Unsaved workbook recovery looks for files Excel captured before a crash or accidental close. It is not the same as opening a deleted file from the Recycle Bin or restoring a previous version from OneDrive, SharePoint or File History. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. For “unsaved excel file”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected cells change, and only then apply the same setup to the full sheet. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. That is what makes a data step that keeps your analysis trustworthy useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
Excel crashes while Book1 has not been saved. Reopen Excel, go to File ▸ Info ▸ Manage Workbook ▸ Recover Unsaved Workbooks and look for a timestamped copy. Open it, inspect the latest changes, then Save As Payroll-Q2.xlsx so it becomes a normal workbook. Recovery content matters because users arrive stressed and need the exact path first, then a realistic explanation of what AutoRecover can and cannot do. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.
In Google Sheets
Everything above works in Google Sheets too. Excel and Sheets share the formula syntax used here; only the surrounding menus are arranged differently. That portability is deliberate — learn it once and it follows you between the two tools and across Windows and Mac. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. The short version of “unsaved excel file”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.
Common mistakes
- Continuing to work for hours before checking recovery, which can overwrite temporary files.
- Assuming AutoRecover is a backup system; it is a crash-recovery helper.
- Recovering the wrong timestamped copy and losing later edits.
- Forgetting cloud version history when the file was stored in OneDrive or SharePoint.
