Convert one JSON document into deterministic, human-readable GitHub Flavored Markdown.
Runs in the browser, in Node, in Go, and on the command line.
Output is a readable projection rather than a reversible serialization format. Every document begins with a # Results
heading (replace or omit it via the heading
option), leaves values bare unless showTypes: true
opts into type annotations — 42 *(integer)*
— and uses canonical spacing: LF endings, one blank line between blocks, no trailing spaces, one final newline.
If you feed JSON into an LLM, you pay for its punctuation. Every {

cheaper and easier for models to follow:

The same conversion runs in the browser, in Node, in Go, and on the command line. The TypeScript and Go implementations produce byte-identical output, enforced by a shared corpus/ and a cross-implementation fuzz gate in CI. Output is a readable
