How to Convert Markdown to JSON
- 1The tool opens in MD → JSON mode by default — paste your Markdown or drag a .md file
- 2Choose a Mode: Document for articles, Table to extract table data, Developer for the raw AST
- 3JSON appears live in the right panel — switch to Preview tab to see rendered HTML
- 4Copy to clipboard or download as a .json file
Need Reverse Conversion Too?
This page is optimized for Markdown → JSON, but the tool also supports reverse conversion when you need a round-trip workflow. Switch to JSON → MD in the left sidebar and the converter will map common JSON structures back into readable Markdown.
- Array of objects → Markdown table for quick README or docs updates
- Doc structure → Markdown document for turning stored content back into an editable draft
- Remark AST → Markdown when you need a true round-trip from parser output
When To Use a Separate JSON to Markdown Page
If your main job is turning JSON into Markdown tables, lists, or full documents, a dedicated landing page is the better fit for search and for clearer instructions.
Use JSON to Markdown if that reverse direction is your primary task.
This page keeps the reverse direction available because it is genuinely useful for round-trip editing, but its main SEO target stays focused on Markdown to JSON.
That split avoids the classic problem where one URL tries to rank for two opposite intents and ends up shadowboxing itself.
Real-World Use Cases
Practical Markdown to JSON workflows, plus one reverse-conversion fallback
MD → JSON
Feed a CMS or Headless API
Your content team writes in Markdown. Your API expects JSON. Use Simple Structure mode to get {title, sections[]} — drop it straight into Contentful, Sanity, or any headless CMS field without a custom parser.
JSON → MD
Round-Trip Structured Content
If you already converted Markdown into JSON and need to turn it back into editable Markdown, switch to JSON → MD. It is useful here as a workflow safety net, not the main reason this page exists.
MD → JSON
Extract Table Data for Analysis
README files often have pricing or comparison tables in Markdown. Use Table Extraction mode to pull out the data as an array of objects — then load it into your script, Google Sheets, or database without manual re-typing.
JSON → MD (Round-trip)
Edit Structured Content as Markdown
If your CMS stores content as JSON, export it, switch to JSON → MD (Doc Structure mode), edit the Markdown, then convert it back. Useful for round-trip editing without forcing this page to rank for the reverse intent first.
Convert a Markdown Table to JSON in One Click
This is the #1 reason developers come here: you have a Markdown table in a README or wiki, and you need the data as a JSON array for a script, database, or API. Switch to MD → JSON mode and select Table — the converter extracts every column and row automatically.
Input — Markdown Table
| Name | Role | Active | |-------|--------|--------| | Alice | Admin | true | | Bob | Editor | false |
Output — JSON Array
[
{
"Name": "Alice",
"Role": "Admin",
"Active": "true"
},
{
"Name": "Bob",
"Role": "Editor",
"Active": "false"
}
]Tip: If your Markdown file has multiple tables, the tool extracts all of them and returns an array of arrays — one per table. Other converters typically only handle the first table or return a flat object.
Frequently Asked Questions
Can I reverse the output back into Markdown later?
Yes. The converter supports JSON → MD for round-trip workflows, including remark AST and structured document formats. That support is here because it is useful after Markdown-to-JSON conversion, but this page is still optimized around the Markdown-to-JSON task.
What's the difference between the MD→JSON output formats?
Full AST gives you the complete remark Abstract Syntax Tree — every node, position, and child. Use this if you're building a parser or need to programmatically walk the document. Simple Structure gives you {title, sections[]} — clean, flat, ready to store in a database. Structured Content adds type metadata per block (heading, paragraph, list, code, quote). Table formats are only for Markdown tables and let you choose between array of objects, 2D array, column arrays, or keyed objects depending on how your downstream code expects the data.
Can I do a full round-trip: Markdown → JSON → Markdown?
Yes. Convert your Markdown to JSON using Full AST output, then switch to JSON → MD and paste the remark Root node back in. The tool uses remark-stringify to reconstruct the Markdown. Semantic content is preserved, though minor formatting details like blank lines or list indentation may normalize.
Does this work for large Markdown files?
Yes. Since all processing happens in the browser, the bottleneck is your device's JavaScript engine — not a server queue. Files up to a few hundred KB convert in under a second on any modern laptop. For very large files (1MB+), the AST output will be large JSON — use the Simple Structure format instead, which produces a much smaller payload by summarizing rather than preserving every AST node.
Is my content sent to any server?
No. Both conversion directions run entirely as JavaScript in your browser tab. Your Markdown and JSON never leave your device. This matters when you're working with API docs that contain auth tokens, internal endpoint URLs, or confidential schema information — all of which are common in the exact documents developers convert most often.
