TSV Validator
Processed Locally
Validate TSV file structure, check for errors, and ensure consistent column counts.
Frequently Asked Questions
The validator checks for: TSV parse errors, inconsistent column counts across rows, empty cells, and overall file structure. It provides a detailed report with row numbers for any issues found.
The validator uses actual tab characters (\t) as delimiters. Make sure your file uses real tabs, not multiple spaces. If you're having issues, check that your editor is not converting tabs to spaces.
Inconsistent column counts are reported as warnings, not errors. While a well-formed TSV should have the same number of columns in each row, the file may still be processable. The validator shows which rows have mismatched column counts.
Empty cells (consecutive tabs with no content) are identified and reported with their row and column numbers. The first 5 empty cells are listed individually. Empty cells are warnings, not errors.
