Repair a Corrupt XLSX or XLS File. Get Your Data Back.
A spreadsheet that won't open isn't always lost. Open the damaged file, let it scan, and rescue every value it can read — numbers, text, dates, whole sheets — then export a clean working file. You see exactly what came back before you pay a cent.

A corrupt spreadsheet tends to fail at the worst moment — the file you need for a deadline throws an error and refuses to open. The reassuring part is that a damaged workbook is rarely empty inside. Most of the time the data itself is intact; what's broken is the wrapping around it — a truncated download, an interrupted save, a damaged archive structure, or contents that no longer match the file's extension. Spreadsheet Repair from Rush Tools is built for exactly this. It opens a broken XLSX, XLSM, XLSB, XLS, or CSV file, scans deep into its structure, and pulls back every value it can read, giving a file you'd written off a real chance of becoming usable again.
The app behaves like a careful recovery tool, not a magic button. When you open a damaged file it scans the contents and rebuilds what it finds: cell values, numbers, formatted text, dates, and as many of the original sheets as survive. It then shows a plain recovery report — what was salvaged and what couldn't be read — so you're never guessing about the result. Every recovered cell can be previewed on screen before you decide anything. When the data looks right, you export a clean, working spreadsheet (or a CSV) that opens normally in your usual app. There's no formula re-engineering and no false promise to reconstruct what's genuinely gone — just the most faithful recovery the file allows.
Everything stays on your device. Your spreadsheet is never uploaded, copied to a server, or routed through the cloud — there's no account to create and nothing phoning home in the background, which matters when the workbook holds financial records, payroll, client lists, or research. Spreadsheet Repair runs on iPhone, iPad, and Mac. Opening, scanning, and previewing the full recovery is free; exporting the repaired file is unlocked with a weekly or annual plan, or a one-time Lifetime purchase. Two honest limits up front: password-protected workbooks are not supported, and a small number of severely damaged files can't be fully recovered — both are flagged clearly so you know where you stand before paying.
The error that won't let your file open.
These are the messages a corrupt or damaged spreadsheet usually shows. Whatever the wording, the fix is the same — open the file here and let it scan for everything still readable inside.
“The file is corrupted and cannot be opened”
The classic dead end — open the file here so the scan can read past the broken wrapper and rescue the values still inside.
“We found a problem with some content”
Part of the workbook is damaged. The scan reads around the bad sections and recovers the cells that survive.
“Excel found unreadable content”
A common sign that a section of the file is corrupt; the app extracts the readable cells the normal opener skipped over.
“The file format and extension don't match”
Usually a file saved or renamed with the wrong extension. The app detects the true format and reads it correctly.
“Errors were detected while saving”
An interrupted or failed save can leave a half-written, unreadable file. Open that file to recover the last good data in it.
“The file is not in a recognizable format”
Often a corrupted header or a truncated archive. The scanner looks deeper than the header to find recoverable content.
“Do you want to recover the contents of this workbook”
If the built-in prompt returns little or nothing, run the same file through a full recovery scan here instead.
“This file is corrupt and cannot be opened”
A damaged XLSX or XLS still typically holds its values — open it to see exactly how much can be rescued.
“Unable to read file”
A generic open failure across spreadsheet apps. The recovery scan tries to extract data the normal opener gave up on.
“The file you are trying to open is in a different format than specified by the file extension”
The contents and the .xlsx or .xls extension disagree. The app identifies the real format and recovers from it.
From broken file to clean export.
Open the broken file
Pick the corrupt or unreadable spreadsheet — XLSX, XLSM, XLSB, XLS, or CSV. It opens on your device; nothing is uploaded.
Scan & recover
The Rush Tools Engine reads deep into the file's structure and rescues every value it can — numbers, text, dates, cells, and surviving sheets.
Review the recovery report
See an honest summary of what was recovered and what couldn't be read, and inspect every rescued cell on screen — all before paying.
Export a clean file
When the data looks right, export a clean, working spreadsheet or CSV that opens normally in your usual app.
Every spreadsheet format, one app.
The modern spreadsheet workbook. Repairs corrupt, truncated, or unreadable XLSX files and exports a clean copy.
Macro-enabled workbook. Recovers the cell data, values, and sheets; the macro code itself is not restored.
Binary workbook format. Scans the binary structure and rescues the values and sheets it can read.
The legacy spreadsheet format. Repairs older, damaged XLS files and recovers the data inside them.
Plain comma-separated data. Reads malformed or broken CSV files and exports a clean, well-formed version.
A careful recovery tool, not a magic button.
Deep Structural Scan
Reads past the broken wrapper of a damaged workbook to reach the data still inside, recovering content a normal open can't reach.
Rescues Every Value It Can
Pulls back numbers, text, dates, individual cells, and as many original sheets as survive — the most complete salvage the file allows.
Honest Recovery Report
A clear, plain-language summary of what was recovered and what couldn't be read, so you're never left guessing about the outcome.
Preview Before You Pay
Inspect every recovered cell on screen for free. Export only unlocks once you can see the recovery is worth keeping.
Clean File Export
Writes a fresh, well-formed spreadsheet or CSV from the rescued data — a working file that opens normally, not a patched-over broken one.
Broad Format Support
Handles XLSX, XLSM, XLSB, and legacy XLS workbooks plus malformed CSV files, all in one app.
100% On-Device
Your file is scanned and rebuilt entirely on your iPhone, iPad, or Mac — no cloud upload, no account, no telemetry.
Straight About Limits
Password-protected workbooks aren't supported, and severely damaged files may not fully recover — both are shown up front, not buried.
See it on every device.
Every scan, preview, and export runs on your device. Your spreadsheet is never uploaded to a server or routed through the cloud — no account, no telemetry, no tracking.
You always see what was rescued and what couldn't be read. No inflated promises — just a clear account of what the file actually allowed.

Repairing corrupt spreadsheets.
Can this really repair a corrupt spreadsheet?
In most cases, yes. A damaged workbook is rarely empty — usually the data is intact and only the file's wrapper is broken. The app scans past that and recovers every value it can, then lets you preview the result before you pay. Some severely damaged files can't be fully recovered, and the report tells you that clearly.
How do I fix an XLSX file that won't open?
Open the file in the app and let it scan. It reads deep into the workbook's structure, rescues the readable cells, numbers, dates, and sheets, and writes a clean, working XLSX you can open normally. You review everything that was recovered before exporting.
Which file types can it repair?
XLSX, XLSM, XLSB, and legacy XLS workbooks, plus malformed or broken CSV files. You can export the recovered data as a clean spreadsheet or as a CSV.
What exactly does it recover?
Cell values — numbers, text, and dates — along with as many of the original sheets as survive. It rebuilds the readable contents of the file. It does not reconstruct live formulas, macros, or formatting that the damage destroyed.
Will it recover my formulas and macros?
It recovers the data and values in your cells and the surviving sheet structure. Live formula logic and XLSM macro code are not rebuilt — the focus is salvaging your actual data, not regenerating code or recalculating a workbook.
Is my file uploaded anywhere?
No. Everything happens on your device. The file is never uploaded to a server, copied to the cloud, or sent anywhere. There's no account to create and no telemetry — which matters when the workbook holds financial or personal data.
Can it open password-protected workbooks?
No. Password-protected and encrypted workbooks are not supported, and the app tells you up front when a file is protected. It does not crack, bypass, or remove passwords.
What does the recovery report show?
A plain-language summary of the outcome: which sheets and how much content were recovered, and what couldn't be read. It's there so you know exactly what you're getting before you decide to export.
Can I see what was recovered before paying?
Yes. Opening, scanning, and previewing the full recovery — every rescued cell — is free. You only pay to export the clean repaired file, so you can confirm the result is worth it first.
My file says the format and extension don't match. Can this help?
Often, yes. That error usually means a file was saved or renamed with the wrong extension, or its contents were partly damaged. The app detects the true format and recovers the readable data from it.
Do I need any other software or a computer?
No. It's a standalone app for iPhone, iPad, and Mac. You don't need a desktop spreadsheet program, a separate repair tool, or any online service.
Does it work offline?
Completely. The entire scan, preview, and export runs on-device, so it works with no internet connection at all and your data never leaves the device.
What does it cost?
Opening, scanning, and previewing recovery is free. Unlimited export of repaired files is unlocked with a weekly or annual plan, or a one-time Lifetime purchase.
What if my file is too damaged to recover?
Some files are damaged beyond full recovery, and the app is honest about it — the report shows what little could or couldn't be read. Because previewing is free, you'll know before paying whether a recovery is worth exporting.
Does it change my original file?
No. The original broken file is left untouched. The app reads from it and writes the recovered data into a separate, clean file, so you never lose the source.
