About TOML and JSON
Understanding the difference between TOML and JSON, and when to convert between them.
What is TOML?
TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy to read and e. It is widely used in Rust projects (Cargo.toml), Hugo static sites, and other developer tools. TOML uses a clear key-value syntax with support for tables, arrays, and rich data types.
What is JSON?
JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. Converting TOML to JSON makes configuration data universally accessible across all programming languages and tools.
