About this tool

Need to translate data configurations between JSON, XML, YAML, or CSV formats? This offline converter handles conversions in a single click.

A key advantage is the TypeScript Type Generator: paste any JSON or YAML payload and get a clean, nested interface declaration immediately. For CSV data, the tool uses an auto-detect algorithm to discover separators.

All conversions run client-side, keeping your configuration keys, data rows, and schemas completely private within your local browser sandbox.

Example. The JSON text {"name":"Ada"} becomes the YAML line name: "Ada".

Limit. The YAML parser only understands indented key lines and dashes, so anchors, multiline block scalars, and tags are rejected.

More in Useful utilities

  • JSON Diff Checker

    Compare two JSON payloads by structure, not by text: see every added, removed and changed key on its own path, entirely in your browser.

  • JSON Formatter

    Beautifully format, validate, compress and sort JSON data locally.

  • JWT Token Debugger

    Decode a JWT header and payload, and compare the signature with HMAC-SHA256 of the secret you type.

  • Keyboard Tester

    Press any key and watch it light up on an on-screen keyboard: check every switch, count simultaneous keys and spot dead or chattering keys.
