CSV Statistics Generator

Generate per-column CSV statistics, including missing values, unique counts, and numeric ranges.

What this tool checks

The report summarizes each column with non-empty and missing counts, unique values, and numeric minimum, maximum, and average where values can be read as numbers. The first row is treated as headings.

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.
