TOML to JSON
Convert TOML configuration files to JSON and vice versa.
About this tool
TOML (Tom's Obvious, Minimal Language) and JSON are two popular formats for storing configuration and data, each with distinct strengths. TOML is designed to be human-readable with a clean, intuitive syntax that avoids unnecessary punctuation, making it ideal for configuration files. JSON, on the other hand, is the de facto standard for web APIs and data interchange, supported by virtually every programming language and tool. This converter lets you seamlessly transform between TOML and JSON, allowing you to use the best format for your needs without manual rewriting.
Using this tool is straightforward: paste your TOML or JSON content into the input field, and the converter automatically detects the format and transforms it to the other. The output is formatted cleanly and is ready to copy and use immediately. Common use cases include converting config files for deployment, adapting data structures for different APIs, and normalizing configuration syntax across projects. Simply paste, convert, and copy—no installation or account needed.
This tool works entirely in your browser, so your data never leaves your device. It handles nested objects, arrays, tables, and inline tables correctly, preserving the structure and meaning of your data during conversion. Whether you're a DevOps engineer managing infrastructure-as-code, a developer integrating APIs, or a config file enthusiast, this converter saves time and eliminates transcription errors.
