What is TOML and JSON conversion and why is it useful?
TOML (Tom's Obvious, Minimal Language) and JSON (JavaScript Object Notation) are both configuration file formats and data serialization standards. TOML uses INI-style sections with key-value pairs for human-readable configuration, while JSON uses nested objects for flexible data representation. Converting between these formats helps modernize configuration systems, improve cross-platform compatibility, and enables seamless data migration between different development environments.

How to use the TOML ↔ JSON Converter tool?
- Paste your TOML or JSON data into the input area
- Choose conversion direction: TOML → JSON or JSON → TOML
- Click 'Convert' to transform the configuration format
- Copy the converted result or use JSON prettification options
Common use cases for TOML ↔ JSON conversion
- Migrate Python project configurations from TOML (pyproject.toml) to JSON APIs
- Convert Rust/Cargo configurations to JSON for web-based tools
- Transform app settings from TOML config files to JSON database entries
- Integrate systems that use different configuration formats
- Modernize legacy configurations to work with contemporary tools and APIs
Frequently Asked Questions
TOML sections (like [section]) become nested objects in JSON. Keys within sections become properties of the corresponding JSON objects, maintaining the hierarchical structure while preserving all data relationships.
The converter supports TOML's strings, integers, floats, booleans, dates/times, arrays, and inline tables. Complex TOML features like table arrays and dotted keys are properly converted to their JSON equivalents.
Yes! All data processing happens 100% in your browser. Your TOML and JSON data never leave your device and are not stored on any server, ensuring complete privacy and security of your configuration data.
