FAQ
Does find unique cell values upload my workbook?
No. Processing happens in your browser, and the selected file is not sent to Calloffice.
How does find unique cell values handle formulas and formatting?
The tool preserves only the elements described on this page; review the downloaded result before replacing a source file.
What is the browser size limit for find unique cell values?
Browser memory varies. This page applies a file or cell limit and stops with an error instead of attempting an unsafe oversized operation.
Does find unique cell values preserve leading zeros?
Text cells such as IDs and postal codes are kept as text where the source parser identifies them that way. Always check a preview before download.
Does find unique cell values overwrite the original file?
No. The tool creates a separate download and does not overwrite the original file.
