How to convert Markdown (README, docs) to structured JSON online

  1. Step 1 – Paste or upload Markdown

    • Paste README, GitHub Markdown, or product/API docs as .md or .markdown.
    • Use the demo button to instantly load realistic content.
    • Works as an online Markdown to JSON converter with no uploads.

  2. Step 2 – Inspect the structured JSON

    • Headings become a hierarchical tree (H1 → H2 → H3) for clear sections.
    • Lists, nested lists, blockquotes, and code blocks are preserved; tables convert to object arrays or 2D arrays.
    • Useful for Markdown-to-JSON pipelines and search indexing.

  3. Step 3 – Copy or download JSON

    • Copy to clipboard or download as a .json file.
    • Use in API payloads, search indexes, AI prompts, static site builds, and docs ingestion.
    • Keep the output as a single source of truth across documentation and pipelines.

Quick tips

  • Keep headings hierarchical (H1 → H2 → H3) to get a clean JSON tree.
  • Code fences preserve the language tag for downstream syntax highlighting.
  • Quotes and lists stay grouped, making it easy to rebuild Markdown/HTML or feed search indexes.

Related tools

  • Round-trip docs across formats for multi-source pipelines.
  • Transform API payloads, documentation assets, and configs with consistent structure.

Frequently Asked Questions

Which Markdown elements are supported and how are they mapped to JSON?

Supported elements include headings (H1–H6) with hierarchical nesting, paragraphs, unordered/ordered lists and nested lists, blockquotes, fenced code blocks (language tag preserved), and tables (converted to object arrays when headers exist, otherwise 2D arrays). Key order and section order follow the original Markdown document.

Is this private and local? Do I need to upload my files?

Conversion runs entirely in your browser—no uploads. Copying or downloading the output does not send data to any server.

How are links and images handled? Will URLs be preserved?

Links like [Text](URL) become Text (URL), and images ![Alt](src "Title") become Alt (image: src, Title). This helps with search indexing and downstream parsing.

How do nested headings appear? Do you support hierarchical JSON?

Headings form a hierarchical tree, with child sections attached to their nearest parent heading. This is useful for sectioned product docs or specifications.

How are tables converted? Can I get an array of objects?

Tables with a header row become arrays of objects (keys from headers). Tables without headers degrade to 2D arrays.

How does it perform with large documents?

The parser is optimized for typical doc sizes. For very large content, consider converting chapter by chapter or in batches.

How do I export or download, and where can I use the JSON?

You can copy to clipboard or download a .json file. Popular uses include API payload generation, search index preprocessing, AI prompts, static site build pipelines, and docs ingestion.

Does it work with other formats?

Pair Markdown→JSON with XML→JSON, YAML→JSON, and JSON→YAML/XML to complete end-to-end pipelines for multi-source documentation and configuration transformations.
