YAML to JSON FREE
Convert YAML to JSON with a safe parser: no tags, no anchors that expand without bound, and no object construction.

CSV, TSV, JSON, YAML, XML, Markdown, HTML, plain text, Excel workbooks, and audio and video. The format is read from the file itself, not from its name.

Columns
Uncheck a column to leave it out, type over a name to rename it, and use the arrows to reorder. The preview below follows.
What was read
How this conversion works
The parser reads the common subset: mappings, sequences, scalars, comments, block strings and inline flow collections. It deliberately does not read tags, anchors or custom types.
That is a security decision, not a shortcut. A YAML parser that can construct arbitrary objects is a remote code execution surface - it is the class of bug behind some of the best known vulnerabilities in several languages - and this parser runs on files from strangers. A document that uses those features is reported rather than half-read.
The JSON that comes out is pretty-printed with two-space indentation and preserves the order the keys were written in.
