Repair a corrupted Excel file (.xlsx) online.
A broken .xlsx may still contain worksheet XML even when Excel cannot open its ZIP package. FileFix scans those parts, repairs recoverable worksheet XML, writes a fresh workbook, and shows limited watermarked worksheet pages in a free preview. A one-time $14 USD — and only if the repair works.
Free preview — pay only if you download ($14 USD)

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
What stopped you continuing? One tap tells us why.
Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
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, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why this happens
An .xlsx can fail at two layers. Its outer ZIP records may be incomplete, or an inner XML member may be malformed. Standard unzip tools address only the container, while Excel requires the workbook relationships and worksheet data to parse as a coherent spreadsheet.
The repair scans local ZIP headers, preserves readable package members, applies fault-tolerant XML recovery to worksheets and shared strings, and writes a new .xlsx. It then loads that output in read-only, values-only mode to enumerate sheets and populated rows.
That validation is deliberately narrower than a promise of perfect workbook fidelity. The preview shows a limited, view-only sample of watermarked worksheet pages from the repaired output; it does not certify every formula or presentation feature.
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)

Questions
The free preview shows complete watermarked worksheet pages as a limited, view-only sample before checkout.
Yes. When repair succeeds, the engine writes and validates a new .xlsx workbook. It does not convert the file to CSV or PDF.
A worksheet whose XML cannot be recovered is excluded rather than inserted as a fake sheet. The preview shows limited watermarked worksheet pages. Inspect the downloaded workbook to check which sheets are included.
