How to remove private information before sharing a CSV

How to remove private information before sharing a CSV. Practical steps, common causes and a matching browser-local DataCleaner tool.

Step-by-step approach

  1. Identify which fields contain personal information and whether sharing is authorized.
  2. Run the CSV Personal Data Scanner to flag likely emails and phone numbers.
  3. Use the redactor for common patterns, then manually inspect names, addresses, identifiers and free text.
  4. Remove unnecessary columns entirely for stronger data minimization.
  5. Share a newly exported file only after reviewing it for remaining sensitive information.

What this does not solve

Browser tools can validate known structures and transform available data, but cannot restore deleted or corrupted bytes, infer unknown business facts, or guarantee that a target system will import every field as intended.
