A CSV quality report should not echo the data it rejects

Short summary

A short piece arguing CSV validation reports should omit rejected raw values for privacy, using only location and reason codes. The author built DataProof CSV, a CLI tool that generates HTML reports with SHA-256 hashes for auditability without echoing sensitive data. Includes explicit AI-assistance and product disclosure.

  • •Validation reports should omit raw rejected values — location and error codes suffice for repair
