How it works
Three steps, no setup
1
Paste your TOML
Config files from Rust, Python, or general app settings all work.
2
Get YAML output
Tables become indented mappings, matching common YAML conventions.
3
Copy into your project
Drop it straight into a .yaml or .yml file.
Common questions
Frequently asked questions
Which tools commonly use TOML?
Rust's Cargo, Python's Poetry, and Hugo all use TOML as their primary config format — this helps when porting settings to a YAML-based system.
Are array-of-tables handled?
Yes, TOML's [[array.of.tables]] syntax is converted into the equivalent YAML list of mappings.
