Tool usage guide
The TOML-JSON Converter is a reliable utility designed to seamlessly transform configuration data between TOML and JSON formats, ensuring your complex data structures remain intact during the conversion process.
Background

Problem
The application cannot parse the TOML file directly, causing startup errors.
How to use
Paste the TOML content into the input, select 'TOML to JSON', and set the indent size to 2.

Problem
Manually rewriting JSON to TOML syntax is error-prone and tedious.
How to use
Paste the JSON metadata into the input, select 'JSON to TOML', and generate the output.
