A Bridge Between Worlds

API Data to Spreadsheets

Convert JSON data from an API into a CSV file that you can easily open and analyze in Excel, Google Sheets, or other spreadsheet software.

Spreadsheets to Web Apps

Convert your CSV data into a JSON array of objects, the standard format for use in web applications and JavaScript.

Formatting Tips

  • For JSON to CSV: Your input should be a valid JSON array of objects. All objects should have the same keys for a clean conversion. Example: `[{"id":1,"name":"A"},{"id":2,"name":"B"}]`
  • For CSV to JSON: Your CSV data should have a header row as the first line. The values in the header row will become the keys in the resulting JSON objects.
