Does #REF! or #VALUE! Mean Your Excel File Is Corrupted?
No. A #REF! or #VALUE! error by itself does not mean your Excel file is corrupted. Microsoft defines #REF! as an invalid reference problem and #VALUE! as a broad formula/input problem. Treat the error as formula-level until you see independent evidence that the workbook structure itself is damaged.
Why #REF! Usually Means the Reference Is Invalid
A real #REF! from linked workbook structured references in Excel for the web from Reddit scenario worked in desktop Excel but showed #REF! in Excel for the web because structured references to linked workbooks were not supported there. That is a compatibility/reference limitation, not proof of corruption.
Microsoft also documents common #REF! causes such as deleted referenced cells, VLOOKUP ranges that do not contain the requested return column, closed-workbook limitations, and unsupported linked-workbook references.
Why #VALUE! Usually Means Formula or Input Trouble
#VALUE! commonly appears when Excel cannot use the supplied data the way the formula expects—for example text where a number is required, hidden spaces, unsupported data types, or other argument problems. Another Reddit report in this same sample described a #VALUE! result tied to a new Excel Lists/nested-array behavior, again showing that an error can come from Excel behavior rather than file damage.
Key Point:
An error code is evidence that a calculation failed. It is not, by itself, evidence that the XLS/XLSX container is corrupted.
When an Error Can Be Part of a Damaged Workbook
Escalate to file repair when formula errors are accompanied by independent corruption signs: Excel reports unreadable content, removes records, fails to open the file, or unrelated sheets/formulas/charts are structurally broken. Try Microsoft's Open and Repair first. For a workbook that is genuinely damaged, Wondershare Repairit Excel File Repair is an appropriate dedicated repair option.

Do not run Repairit just because you see #REF! or #VALUE!. Use it when the workbook also shows file-level corruption. Repair a copy and validate formulas, references, and sheets after repair.
