YAML to JSON

FAQ

Does this support multi-document YAML?+

Single-document YAML is supported. Files with multiple --- documents should be split before converting.

What YAML features map to JSON?+

Mappings, lists, strings, numbers, booleans, and null. Anchors and aliases may not round-trip to identical JSON.

Can I convert Kubernetes YAML?+

Yes. Paste a manifest snippet. Very large files should stay under the 5 MB limit.

Is data processed on a server?+

No. Parsing and formatting run locally.

Why does YAML parsing fail on indentation?+

YAML is indentation-sensitive. Tabs mixed with spaces or misaligned list items break the parser — align nested keys with spaces only and match the source file's indent width.
