RomitCSV
Free CSV validation tool

CSV Schema Validator

Validate CSV column names and order against an expected schema that you provide.

What this tool checks

Enter the expected column names one per line. The validator checks for missing, unexpected, or out-of-order headings. Header names are compared exactly after trimming surrounding whitespace.

How to use it

  1. Choose a CSV or TSV file up to 50 MB.
  2. Set any requested options and run the check.
  3. Review the report or download it as a CSV file.

The file is read and analyzed in your browser. It is not sent to the RomitCSV server. Use the CSV Validator for a general structure check or browse all CSV tools.
