Frequently Asked Questions
What is TOML?
TOML (Tom's Obvious Minimal Language) is a configuration file format that is easy to read and write. It is commonly used for application configuration files such as Cargo.toml in Rust and pyproject.toml in Python.
How does this TOML formatter work?
The formatter parses your TOML input, validates its structure, and outputs a consistently formatted version with proper spacing around equals signs and organized sections.
What TOML features are supported?
This tool supports key-value pairs, tables (sections), nested tables, arrays, inline tables, strings, integers, floats, booleans, and datetime values as defined in the TOML specification.
Is my data safe?
Yes! All processing happens entirely in your browser. Your TOML data is never sent to any server. No data is collected, stored, or transmitted.
Where is TOML commonly used?
TOML is popular in the Rust ecosystem (Cargo.toml), Python packaging (pyproject.toml), Hugo static site generator, and many other tools that need human-friendly configuration files.
