How to use CSV Formula Exposure Auditor
Inspect an existing document before choosing a destination application. Findings show the original cell and an illustrative apostrophe-prefixed copy; the source remains untouched.
- Enter input.
- Choose the settings for csv formula exposure auditor, then run the tool.
- Review the result and any limitations before copying or downloading it.
Good to know
- Up to100,000 input characters,5000 records and100 columns per table. Downloads quote cells, protect formula-like values and disambiguate colliding exported headers.
- Detection only, including header cells. Negative numbers can be flagged intentionally. Illustrative prefixes are not a universal spreadsheet-safety guarantee.
- Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
Common questions
Does no finding prove a CSV is safe?
No. Spreadsheet import behavior varies. This checker evaluates only the named prefix pattern and never executes cells.
Is this input sent to a server?
No. The application processes this input inside your browser tab and does not save it to persistent storage.
