"This workbook cannot be opened or repaired…".
Excel showed "This workbook cannot be opened or repaired by Microsoft Excel because it is corrupt," which means its own repair path has already given up. FileFix uses a different rebuild — scanning surviving members and writing a fresh workbook — and shows limited watermarked worksheet pages first. 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.

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
This message is Excel's final verdict: it recognized the file as a workbook, attempted its built-in Open and Repair, and could not produce a document it would open. It does not identify which member is damaged or prove that every sheet is unrecoverable.
The cause is usually a damaged ZIP index or a worksheet and shared-string XML that Excel's parser rejects. Because Excel's repair works within its own strict rules, a package it declines can still hold readable members that a more tolerant rebuild can extract.
FileFix reads the local ZIP records directly, recovers worksheet and shared-string XML where possible, writes a new .xlsx, and validates it with an independent workbook reader. The preview shows limited watermarked worksheet pages from the rebuilt workbook before paying.
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 watermarked preview You see watermarked pages of the recovered worksheets.
-
Pay & download If the preview shows what you need, unlock the repaired Excel file for a one-time $14 USD.
You see watermarked pages from your rebuilt workbook before you decide anything — so you never guess.

Questions
Yes, when the failure is in parts Excel refuses to read rather than truly absent data. FileFix uses a more tolerant rebuild and only offers checkout when it can produce and validate a repaired workbook.
Excel enforces strict package rules and stops when a member breaks them. A separate engine can salvage readable members and rebuild a valid container, though it cannot restore parts that were genuinely lost.
Only the sheets whose XML can be recovered are included; unrecoverable sheets are left out rather than faked. The free preview shows limited watermarked worksheet pages. Inspect the downloaded workbook to check which sheets are included.
