Frequently Asked Questions

📌 What YAML features does the converter support?

It supports YAML 1.2 core syntax: key-value pairs, strings, numbers, booleans, null, arrays, nested mappings, multi-line strings, and anchors and aliases.

📌 Why convert between YAML and TOML?

YAML is widely used in Kubernetes, Docker Compose, GitHub Actions etc., but is prone to indentation errors. TOML has stricter syntax with clearer error messages.

📌 How accurate is the conversion?

The tool first parses YAML into a universal data model, then generates TOML from that model. This intermediate model ensures type and structure consistency.

📌 Does it support multi-document YAML (--- separated)?

Yes. Multi-document YAMLs are converted document by document. By default only the first document is converted, but you can choose to convert all documents.

📌 Is my data secure?

Absolutely. This tool runs 100% in your browser. Your data is processed locally in memory and is never uploaded to any server. The data is cleared immediately after processing.
