// About this tool

Generate TOML configuration from JSON for Rust, Python, or other projects. Paste JSON and copy the converted TOML. Nested objects become TOML tables and arrays.

// How to use it

  1. Paste valid JSON into the input.
  2. Review the generated TOML.
  3. Copy the output or swap the direction.

// Frequently asked questions

Are all JSON values supported?

TOML supports strings, numbers, booleans, arrays, and tables; some JSON-specific structures may not map cleanly.

Is my JSON uploaded?

No. Conversion happens locally in your browser.
