"Removed Records: Formula from /xl/calcChain.xml" — what it means.
Excel reports "Removed Records: Formula from /xl/calcChain.xml" when it discards damaged formula-calculation metadata while repairing a workbook. Upload the original .xlsx for a separate repair attempt and see a free summary of the sheets, rows, and masked cells in the rebuilt copy.

Good 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. You can try another file.
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.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, and document files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, ZIP, and PDF). We're adding support for more formats over time.

Why this happens
The /xl/calcChain.xml part records the order in which Excel recalculates formula cells. A formula reference that points to a missing cell or sheet, malformed XML in that part, or relationships that no longer agree with the workbook can cause Excel to remove calculation-chain records during recovery.
The calculation chain is metadata, but its removal does not verify that the formulas or their dependencies are intact. The worksheet XML may still contain formula expressions while cached values, references, or related worksheet parts have separate damage, so the recovered workbook must be inspected and recalculated in Excel.
FileFix scans the surviving package members, repairs worksheet and shared-string XML where possible, writes a fresh .xlsx, and validates it with an independent reader. The free summary verifies recovered sheets, populated rows, and sampled values; it does not promise formula or recalculation behavior.
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
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. Files auto-delete within 48 hours.
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.
