Excel workbook recovery options and guides.
Upload an Excel file that won't open. We rebuild it from what's still inside and show you a free recovery summary — sheet names, row counts, and a sample of recovered cells. If the summary shows what you need, unlock the repaired Excel file for a one-time $14.

Repair your file
Choose a supported file to see what can be repaired before checkout.
Simulated checkout — no payment is processed.
Optional — we'll email your private download link.
You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.
Try another fileGood news — your file isn't damaged. No charge.
There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.
We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why Excel workbooks stop opening
Modern Excel files are ZIP archives holding XML parts for worksheets, shared text, styles, relationships, and workbook metadata. Excel needs both the outer ZIP index and the inner XML to be readable and consistent before it will open the workbook.
An interrupted save or transfer can remove the ZIP central directory at the end of the file. A different failure can leave a worksheet or shared-string XML part cut off or malformed. Either problem can make Excel reject the whole workbook even when other members remain readable.
FileFix scans local ZIP records instead of depending on the central directory, recovers readable members, repairs worksheet and shared-string XML where possible, and writes a fresh .xlsx container. It then opens the result with an independent workbook reader; only a validated workbook proceeds to a recovery summary.
The summary reports the sheet names, populated row counts, and a masked cell sample that the repaired file actually contains. It does not claim that missing bytes, unsupported .xls data, passwords, or package features that were not recovered can be restored.
You never install anything, and you don't create an account to try it. You upload, you read the recovery summary, you decide.
What we can and can't recover
We can usually fix
- Files that show "Excel found unreadable content"
- Files Excel calls an invalid format or extension
- Workbooks cut off mid-save or mid-transfer
- Files that show the right size but won't open
We can't fix
- Password-protected/encrypted workbooks
- Genuinely empty (0-byte) files
- Deleted or formatted files (that's data recovery, a different job)
- The old binary .xls format (this repair is for .xlsx)
How it works
-
Upload Drop the file in. It uploads over an encrypted connection. The repair runs automatically — no person looks at your file.
-
Free Recovery Summary You see exactly what we recovered — sheet names, row counts, and a small sample.
-
Pay & Download If the summary shows what you need, unlock the repaired Excel file for a one-time $14.
You see a recovery summary built from your actual file before you decide anything — so you never guess.

Questions
An .xlsx file is a ZIP container of XML parts. FileFix scans the parts that are still readable, repairs malformed worksheet and shared-string XML where it can, writes a fresh workbook container, and verifies that the result opens as an Excel workbook before offering it.
It lists the recovered sheet names and row counts, plus a small masked sample from the first sheet. The sample hides parts of cell values; it is evidence from the repaired workbook, not a generic example.
The engine preserves readable package parts, but the summary only verifies sheets, populated rows, and sampled cell values. It does not promise that every formula, style, chart, relationship, or embedded object survived. Review the downloaded workbook in Excel before relying on those features.
No. This repair is for the modern .xlsx format. The older .xls format is a different binary structure and is not handled by this engine.
No. Encryption prevents the repair engine from reading the workbook parts. FileFix does not remove or bypass workbook passwords.
The rebuilt workbook contains the worksheet parts the engine can recover and validate. The free summary names the sheets and counts the rows found in the repaired result, so you can decide from that evidence before checkout.
A one-time $14 — and only if the repair works. The recovery summary is free, and a file that does not produce a validated repaired workbook is not offered for checkout.
No. Upload, repair, validation, and summary generation are automated. Originals of successful repairs are deleted when your repair is delivered; unrepaired files are kept encrypted for up to 30 days, then deleted.
No. The repair runs on FileFix's servers. You will need a compatible spreadsheet app to review and use the downloaded .xlsx file.
File repair can reorganize bytes and XML that still exist; it cannot recreate cells that never reached the file. If the engine cannot build and validate a readable workbook, there is no checkout.
Yes, when a clean source or version history is available. A complete original is better than any repair because no repair can recreate bytes that are absent. Keep the damaged copy until you have verified the replacement.
No. The summary reads sheet names, populated rows, and sampled values from the rebuilt workbook. It does not test external links, queries, data connections, macros, or recalculation behavior.
No. FileFix reads the uploaded file and creates a separate repaired workbook. The source file on your device is not modified.
