Paste YAML and get clean JSON instantly, entirely in your browser.
Last updated: August 8, 2026
Convert YAML to JSON instantly in your browser using a real YAML parser (js-yaml) — supports nested objects, lists, anchors, and standard YAML syntax.
A: This uses js-yaml, a full YAML 1.2 parser, so nested mappings, sequences, anchors/aliases, multi-line strings, and standard scalar types are all supported — not just a basic subset.
A: YAML is whitespace-sensitive — mixed tabs/spaces or inconsistent indentation are the most common causes. The error message includes the line number to help you locate it.
A: No. Parsing happens entirely in your browser — pasted or uploaded content is never sent to a server.
