Markdown to JSON
Parse a Markdown document into a structured JSON array of typed block objects — each heading, paragraph, ordered or unordered list, table, blockquote, code fence, and horizontal rule becomes its own JSON element with a type field and relevant content properties. This makes it easy to programmatically process, render, or transform Markdown content without writing your own parser. Paste any Markdown text and the JSON output updates instantly in your browser with no server calls.

What is Markdown to JSON Converter?
Convert Markdown documents — including tables, front matter, headings, and lists — into structured JSON in your browser — no upload, no account required. This browser-based tool parses YAML or TOML front matter into a JSON metadata object, converts Markdown tables into arrays of objects, and represents heading hierarchies as nested JSON trees. It is used by static site developers extracting content for headless CMS APIs, technical writers building structured documentation pipelines, and developers testing Markdown parsers. All conversion happens locally, so your draft documents and private notes never leave your device.
How to Use
- 1
Paste Your Markdown
Paste your Markdown document into the input panel. Documents with YAML/TOML front matter, pipe tables, heading hierarchies, and nested lists are all supported.
- 2
Select Extraction Mode
Choose "Front Matter Only" to extract the YAML/TOML header block as JSON, "Tables" to convert Markdown pipe tables into arrays of objects, or "Full Document" for a complete structured JSON representation of headings, paragraphs, and blocks.
- 3
Parse to JSON
Click "Convert to JSON". Front matter is parsed with a YAML/TOML parser; tables are extracted row by row; headings become nested JSON sections. The output appears with syntax highlighting.
- 4
Copy or Download
Copy the JSON output for use in a static site pipeline, CMS import, or content processing script — or download it as a .json file.
Common Use Cases
Static Site Content API
Convert Markdown files with YAML front matter into JSON to serve as a lightweight content API for Gatsby, Next.js, or Astro static sites, enabling dynamic content rendering from Markdown sources.
Documentation Table Extraction
Extract Markdown tables from README files, wikis, or technical docs into JSON arrays for programmatic processing, bulk editing, or importing into spreadsheets and databases.
Blog Post Metadata Processing
Parse YAML/TOML front matter from Markdown blog posts into JSON to build tag clouds, category indexes, date-sorted archives, or search indexes without a full CMS.
Content Pipeline Automation
Convert Markdown content files to JSON as an intermediate format in content pipelines that transform, validate, or enrich content before publishing to headless CMS platforms or CDN-hosted APIs.
Conversion Examples
Markdown Front Matter → JSON Metadata
YAML front matter is parsed into a flat JSON metadata object.
Input JSON
--- title: "Getting Started with JSON" date: "2024-01-15" tags: ["json", "tutorial", "beginner"] author: "Alice" --- ## Introduction JSON is a lightweight data format...
Output CSV
{
"title": "Getting Started with JSON",
"date": "2024-01-15",
"tags": ["json", "tutorial", "beginner"],
"author": "Alice"
}Markdown Table → JSON Array
A Markdown pipe table becomes an array of objects with header keys.
Input JSON
| name | role | level | |-------|-----------|--------| | Alice | Engineer | Senior | | Bob | Designer | Mid |
Output CSV
[
{"name": "Alice", "role": "Engineer", "level": "Senior"},
{"name": "Bob", "role": "Designer", "level": "Mid"}
]
