How to scan an excel workbook for all formula errors
- Step 1Upload your Excel file — Drop an .xlsx or .xls workbook. SheetJS parses every cell in every sheet.
- Step 2Locate errors — The tool lists every error cell with its sheet, address, error code, and the formula that caused it.
- Step 3Download the error report — Save the report as a text file for sharing with your team or attaching to a bug ticket.
Frequently asked questions
Can it also fix the errors?+
Locating only in this version. The Logic Detective suite (Formula Explainer, Format Inspector) helps you understand the cause. Fixing is manual.
Does it find errors hidden by IFERROR()?+
No. Cells wrapped in IFERROR() show their fallback value and are not flagged. Only cells that display an error code are detected.
What about circular reference errors?+
Circular references are a different type of error not stored as a cell error code. The Circular Reference Finder (planned) will address these.
