Before converting

How to get a cleaner result

  • For developer tools, validate the result before using it in production code or API requests.
  • Try the built-in sample first to understand the expected input shape.
  • Check that the input is complete before copying or downloading the output.
  • If an error appears, reduce the input to a smaller section and test again.

Common issues

What to check if something fails

  • Syntax errors usually come from missing brackets, quotes or separators.
  • Formatted output should still be validated before use.
