Convert JSON to TOML configuration format
What is JSON to TOML?
JSON to TOML converts JSON data to TOML (Tom's Obvious Minimal Language) — a configuration format used by Rust (Cargo), Python (pyproject.toml), and other modern tools.
When to use this tool
- Converting JSON config to TOML for Cargo or pyproject.toml
- Generating TOML configuration from JSON data
- Migrating settings between config formats
- Creating human-readable config files from programmatic JSON
How it works
Parses the JSON and maps objects to TOML sections (tables), arrays to TOML array syntax, and scalars to TOML value types. Nested objects become nested table headings.
