Good uses

  • Find rows that break import.
  • Check quotes, delimiter shape, and empty rows before exporting to XLSX.

Bad inputs

  • Private production exports with secrets.
  • Files whose target system has custom business rules beyond CSV syntax.

Output checklist

  • Confirm row count.
  • Fix delimiter and quote issues.
  • Profile columns before final import or spreadsheet export.

Failure modes

  • Malformed quotes can stop parsing.
  • Wrong delimiter choices create misleading columns.
  • Valid CSV can still violate destination schema.

Runtime limits

  • Browser-local.
  • Syntax and structure validation only.
  • No upload to Convurter.
