Converted entirely in your browser — your data never leaves your device

How to use it

  1. 1 Paste your source data into the input panel or load a local text file when available.
  2. 2 Adjust any visible conversion settings, such as a table name or interface name.
  3. 3 Run the converter in your browser.
  4. 4 Review the output, then copy or download the result.

Use cases

  • Move small datasets between developer-friendly formats
  • Prepare examples for docs, tests, migrations, or config files
  • Inspect structured data without opening a spreadsheet or editor extension

Limitations

  • The schema marks observed object fields as required and infers primitive, object, and array types.
  • Very large files depend on browser memory and device performance.
  • Malformed or highly specialized data may need manual cleanup before or after conversion.
