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.

  1. Enter input.
  2. Choose the settings for csv formula exposure auditor, then run the tool.
  3. 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.
