TOML Converter

TOML Converter transforms data between TOML (Tom's Obvious Minimal Language) and JSON formats bidirectionally, preserving all data types including integers, floats, booleans, datetime values, arrays, and inline tables. TOML is widely adopted as the configuration format for Rust projects (Cargo.toml), Python packaging (pyproject.toml), Hugo static sites, and many DevOps tools because of its clean syntax and explicit data typing. This converter enables seamless interoperability between TOML-based tools and JSON-native platforms, and provides a quick way to visually compare the two formats side by side.

How to Use

Paste your TOML content into the input area and click Convert to JSON to receive a structured JSON representation. To convert in the opposite direction, paste JSON and click Convert to TOML. The tool validates syntax on input and displays line-specific error messages for malformed TOML or invalid JSON. TOML-specific types such as datetime values and multi-line basic strings are correctly mapped to their JSON equivalents. Copy the output to replace configuration files or for use in tooling that requires the other format.

Common Use Cases

• •Converting Rust Cargo.toml dependency and workspace settings to JSON for tooling or documentation that requires JSON input
• •Transforming Python pyproject.toml build and dependency metadata to JSON for comparison with package.json or analysis tools
• •Editing complex TOML configuration files as JSON in editors that provide superior JSON schema validation and IntelliSense
• •Comparing TOML and JSON representations of the same configuration structure during a format migration or documentation review
• •Converting Hugo site configuration files or Netlify TOML deployment settings to JSON for automated processing in CI pipelines
