FAQ
Does Find External Workbook Links upload my workbook?
No. Processing happens in your browser. The page does not send workbook contents to a server.
Will Find External Workbook Links overwrite the original file?
No. It creates a separate download, so your selected source file remains unchanged.
How are blank cells handled?
Empty cells are distinguished from zero and from text containing spaces. Optional trimming only affects text values.
Are formulas recalculated like desktop Excel?
No. Formula text can be preserved or inspected, but this browser tool is not Microsoft Excel's calculation engine.
What size workbook should I use?
For dependable browser performance, use files under 40 MB and worksheets below 750,000 cells. Split larger files first.
