What is TOML to JSON Converter?
Need to convert your TOML (Tom's Obvious, Minimal Language) configuration files to JSON (JavaScript Object Notation)? This tool converts TOML to JSON instantly. Perfect for converting TOML config files to JSON format for APIs or web applications.
According to the TOML v1.0.0 specification, TOML is a configuration file format that's easy to read and write. JSON is the standard format for APIs and data exchange. Converting TOML to JSON makes your configuration data accessible in JSON-based systems or APIs.
Everything happens in your browser – your TOML never leaves your computer. Convert, download, and use your JSON file right away.
