Paste YAML and get formatted JSON back. The parser covers nested maps, block sequences, inline lists, and common scalars (strings, numbers, booleans, null). Everything runs in your browser — nothing is uploaded.
Nested maps, block sequences, inline lists such as [a, b, c], and common scalars including strings, numbers, booleans and null. Anchors and aliases, multi-line block scalars, and flow mappings are not supported and will not convert correctly.
Everything from a # to the end of a line is treated as a comment and stripped, including inside quoted strings. If a value must keep a literal #, avoid in-place hashes or re-add them after conversion.
No. Parsing runs entirely in your browser and the text never leaves your device, so it is safe to paste internal configuration files here.
