JSON to TOML

This lesson is part of Web Developer Tools · All levels

Summary

The JSON to TOML converter converts JSON data into a TOML configuration format that uses a row key = value and a nested table. A nested object is usually a table with a header [name], whereas an array of objects is an array of tables [name]. TOML supports strings, numbers, booleans, dates, and arrays, but has no value null. The conversion results need to be checked because the difference in the rules of the interformat type can change the representation of the data.

Key points

JSON objects are mapped to a TOML table with a header [name]
Array of objects to array of tables
TOML does not have a null type, so the null value needs special handling
The TOML string uses double quotes and escape backslash.
TOML is popular for configuration files such as Cargo.toml and pyproject.toml
