OSHA ITA CSV Validator

Validate OSHA Form 300A and 300/301 CSV files before uploading to the Injury Tracking Application. Files stay in your browser.

Why this happens

ITA batch files must follow OSHA’s published headers, order, formats, and consistency rules. A small spreadsheet conversion can reject an otherwise complete filing.

What RuleTally checks
Administrative checks based on the current published ITA file guidance.
  • Official header names and order
  • Required fields and accepted codes
  • Dates, time, EIN, ZIP, and NAICS formats
  • 300A case and illness total consistency
  • Possible PII patterns in 300/301 narratives
