Convert JSON to MD for your agents

A developer released json-to-md, an open-source tool that converts JSON documents into deterministic, human-readable GitHub Flavored Markdown. The tool runs in the browser, Node, Go, and on the command line, with TypeScript and Go implementations producing byte-identical output. It aims to reduce token usage when feeding data to LLMs by replacing JSON punctuation with Markdown structure.

Convert one JSON document into deterministic, human-readable GitHub Flavored Markdown https://github.github.com/gfm/ . 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 { , } , " , : , and , is tokens spent on structure the model does not need to read the data. Converting the same document to Markdown headings and lists is measurably cheaper and easier for models to follow: Convert one JSON document into deterministic, human-readable GitHub Flavored Markdown https://github.github.com/gfm/ . 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/ https://github.com/rajnandan1/json-to-md/corpus/ and a cross-implementation fuzz gate in CI.
