}What is TOML to JSON?
TOML is the standard configuration format for Rust (Cargo.toml), Python (pyproject.toml), and many Go projects. Converting to JSON enables consumption by systems, APIs, and tooling that expect JSON. The converter handles the 95% case: key-value pairs, table sections, arrays, standard strings, numbers, and booleans. Complex features like inline tables and dotted keys are partially supported.
How to convert TOML to JSON
- 1Paste your TOML configuration.
- 2The JSON output updates live.
- 3Copy the JSON output or download as a .json file.
Frequently Asked Questions
What is TOML?
TOML (Tom's Obvious, Minimal Language) is a configuration file format designed for readability. It's the standard config format for Rust (Cargo.toml), Python (pyproject.toml), and Go projects.
Does the converter support all TOML features?
It supports key-value pairs, table sections, arrays, strings, numbers, and booleans. Inline tables and dotted keys are partially supported. For complex TOML, use a dedicated parser library.
Why convert TOML to JSON?
JSON is more widely supported in web APIs and tooling. If your config needs to be consumed by a JavaScript frontend or a JSON-only system, convert to JSON first.
