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. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “corrupted excel file recovery”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. 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. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.
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. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.
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 “corrupted excel file recovery”: 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.
