When to use this conversion

  • Remove unnecessary whitespace from a JSON file.
  • Prepare a compact JSON fixture for transfer.
  • Keep a smaller text copy for a data pipeline.

Best practices

  • The file must contain valid JSON; comments and trailing commas are not accepted.
  • Formatting changes whitespace only; it does not repair invalid data.
  • Keep a copy of the original file before replacing it in a project.
