TOML to INI Converter

Summary

This tool converts TOML (Tom's Obvious Minimal Language) configuration files into the classic INI format used by many applications and frameworks. Conversion happens entirely in your browser — no files are sent to any server. Nested TOML tables become bracketed INI sections, and arrays of primitives are serialized as comma-separated values.

How it works

1. Paste or type your TOML configuration into the left panel.
2. The converter parses the TOML and maps keys to INI key=value pairs.
3. Nested tables (e.g. [database]) become INI sections like [database].
4. Deeply nested tables use dot notation in the section name (e.g. [server.tls]).
5. Click "Copy Output" to copy the resulting INI text to your clipboard.

Use cases

• Migrate application config from TOML to INI format.
• Convert Cargo.toml or pyproject.toml sections for legacy tooling.
• Inspect TOML structure as flat key=value pairs for debugging.
• Generate INI files for PHP, Python ConfigParser, or Windows apps.
• Quickly prototype config formats before committing to one standard.
• Cross-reference TOML and INI representations side-by-side.
