What is TOML ↔ JSON Converter?

TOML ↔ JSON Converter transforms data between TOML and JSON formats. TOML is the configuration format used by Rust (Cargo.toml), Python (pyproject.toml), and many modern tools. This converter makes it easy to switch between TOML's human-friendly syntax and JSON's universal format.

How to Use

  1. Paste your TOML or JSON data into the corresponding panel
  2. Select the conversion direction (TOML → JSON or JSON → TOML)
  3. Click Convert and copy the result

Use Cases

  • Converting Cargo.toml dependencies to JSON for programmatic analysis
  • Migrating pyproject.toml settings between formats
  • Working with Hugo, Deno, or other tools that use TOML configuration
  • Inspecting and modifying TOML configs in a more familiar JSON format

Privacy & Security

All processing happens entirely in your browser. Your configuration data is never sent to any server.
