Converting TOML Configuration to JSON
TOML's table-based structure maps directly to JSON objects. Top-level key-value pairs become root-level JSON properties. TOML section headers like [database] become nested JSON objects. TOML array-of-tables ([[servers]]) become JSON arrays of objects โ each [[servers]] block appends a new object to the array.
This is particularly useful when a tool or API you're integrating with requires JSON input, but your configuration source is a TOML file (such as Cargo.toml, pyproject.toml, or a Hugo config). Rather than manually translating the structure, paste your TOML here and get JSON you can use directly.
TOML Scalar Types
TOML has richer scalar types than JSON. TOML dates and datetime values (1979-05-27, 1979-05-27T07:32:00Z) are converted to JSON strings since JSON has no native date type. TOML integers and floats map directly to JSON numbers. TOML hex integers (0xFF), octal (0o17), and binary (0b1010) are converted to their decimal JSON equivalents.
Comments Are Discarded
TOML supports comments (lines starting with #), but JSON does not. When converting TOML to JSON, all comments are discarded. If you need to preserve intent, consider adding the comment text as a separate string field before converting.
