TOML to JSON

Overview

• Converts TOML-formatted data into JSON format.
• TOML is a notation designed for configuration files, used by many development tools such as Rust's Cargo.toml and Python's pyproject.toml.
• TOML's date type (e.g. 1979-05-27T07:32:00Z) is converted to an ISO 8601 string in the resulting JSON.

Usage

1. Enter the TOML you want to convert into the text area.
2. Click the "Convert" button.
3. The result, converted to JSON format, is displayed below. Use the "Copy" button to copy it to the clipboard.

Example

[package]
name = "my-app"
version = "0.1.0"

{
  "package": {
    "name": "my-app",
    "version": "0.1.0"
  }
}

Use Cases

• Reviewing the contents of a Rust (Cargo.toml) or Python (pyproject.toml) configuration and passing it as JSON to a script
• Converting a TOML configuration file to read it more like JSON
• Converting TOML-formatted data to pass it to a JSON-based tool or API

FAQ

Notes

• Parsing follows the TOML 1.0 specification. TOML that violates the spec, such as redefining the same key, is shown as an error.
• Converting very large TOML data (several MB or more) may make browser processing slow.
