TOML ⇄ JSON Converter
Convert between TOML and JSON formats instantly.
TOML is a configuration file format designed to be easy to read and write (used by tools like Cargo/Rust and many modern app configs), while JSON is the universal data-interchange format. This tool converts between TOML and JSON, useful when you need to feed a TOML config into a JSON-only system or vice versa.
Frequently asked questions
Configuration files - it's popular in the Rust ecosystem (Cargo.toml) and various modern application configs because of its clear, unambiguous syntax for nested data and dates.
TOML has native support for dates/times as a first-class type; when converting to JSON (which has no native date type), dates are typically represented as strings, and vice versa when converting back.
Invalid TOML syntax will fail to convert, effectively acting as a validation check - the tool will indicate that something in the input couldn't be parsed.
