FAQ
Common questions and answers about this topic.
What is the difference between YAML and TOML?
YAML uses indentation-based nesting and is flexible with data types, while TOML uses a flat key-value syntax with explicit sections (tables) and strict typing. YAML is common in Kubernetes and CI/CD, TOML in Rust/Python configs.
Can I sort the keys alphabetically?
Yes, with the sort keys dropdown you can alphabetically reorder all TOML table keys (A to Z) or preserve the sequence from your YAML mappings. Sorting is applied recursively to every nested table and sub-table in the TOML output.
When would I need to convert YAML to TOML?
Common scenarios include migrating Kubernetes or Docker Compose configs to Rust Cargo.toml, setting up Python pyproject.toml from existing YAML configs, or switching between CI/CD pipeline formats.
Is my data sent to any server?
No, the YAML-to-TOML conversion is handled entirely by JavaScript in your browser. Your YAML data remains on your device and is never shared with any server.
