INI to TOML Converter

Summary

This tool converts INI-format configuration files into valid TOML documents entirely in your browser. It handles sections (which become TOML table headers [section]), key=value pairs (with automatic type detection for strings, integers, floats, and booleans), and skips comment lines beginning with ; or #. No data is transmitted to any server.

How it works

1. Paste or type your INI content into the left panel.
2. The converter parses each line: blank lines and comments are skipped, [Section] headers become TOML table headers, and key=value lines are converted with type detection.
3. String values are quoted; integers, floats, and booleans are written unquoted per the TOML spec.
4. Click "Copy TOML" to copy the result to your clipboard.
5. Use "Clear" to reset both panels and start over.

Use cases

• Migrate legacy INI config files to TOML for modern tools like Rust, Hugo, or Cargo.
• Convert application settings from .ini format to TOML-based configuration.
• Inspect and reformat INI content as structured TOML for readability.
• Quickly prototype TOML config schemas from existing INI templates.
• Validate INI structure by reviewing the resulting TOML hierarchy.
