Excel was unable to read this file
"Excel was unable to read this file" means the application could not build a usable workbook from the package it opened. Upload the original .xlsx for an independent rebuild and see limited watermarked worksheet pages before checkout. A one-time $14 USD — and only if the repair works.

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
Excel can reject a workbook when ZIP records, worksheet XML, shared strings, or package relationships are missing or malformed. The broad message does not identify which member stopped parsing.
Readable worksheet records can remain even when the surrounding package is inconsistent. Recovering them requires scanning surviving members and writing a fresh workbook container.
FileFix repairs recoverable worksheet and shared-string XML, validates the rebuilt .xlsx with an independent reader, and shows limited watermarked worksheet pages from that result.
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
Excel could not build a usable workbook from the package it opened. Damaged ZIP records, worksheet XML, shared strings, or package relationships can cause this message; it does not identify the specific damaged part.
No. Readable worksheet records may remain inside an inconsistent package. A rebuild can only recover content still present in the uploaded file; it cannot recreate missing sheets or cells.
Keep the original unchanged. Try downloading a fresh copy from the source, checking version history, or running Excel's Open and Repair on a separate copy. Review any recovered workbook before relying on it.
FileFix scans surviving .xlsx package members and rebuilds recoverable worksheet and shared-string XML into a fresh workbook, then validates it with an independent reader. A different rebuild may help, but recovery is not guaranteed.
If a validated workbook is available, the free preview shows limited watermarked worksheet pages from it. Check the visible content before checkout, and compare the downloaded workbook with your expected sheets and cells; validation does not prove that absent content was recovered.
