Answers

Frequently Asked Questions

Q Is my YAML data sent to any servers?

No. The conversion is processed entirely in your browser using local Javascript modules, guaranteeing privacy.

Q Does this support YAML lists and sequences?

Yes. All YAML sequences (using dash prefixes) are accurately mapped to standard JSON arrays.

Q Can I use tab characters in YAML?

No, YAML standards prohibit tabs. Use double spaces for indentation. The editor highlights any invalid tab spaces automatically.

Q Can I convert back from JSON to YAML?

Yes, you can toggle the target preview format to YAML to check bidirectional conversion instantly.

Q What size limit applies?

Since processing is client-side, it easily handles massive config payloads without timeouts.
