Pro Tips

  • For CSV to JSON conversion, ensure your first row contains headers-they'll become the JSON object keys.
  • Use the preview panel to verify nested structures are flattening correctly before downloading large files.
  • When converting arrays, each array element becomes a separate CSV row with matching column headers.
  • Try semicolon delimiters if you are working with European spreadsheet applications that use comma as decimal separator.
