Markdown ➜ JSON AST Conversion Guide

Learn how to use the live converter below to turn any Markdown document into a fully-fledged JSON Abstract Syntax Tree (AST). The tool supports three popular parsing engines – Pandoc, Remark and markdown-it – and lets you copy or download the result with a single click.

Why JSON AST instead of plain HTML?

Converting Markdown directly to HTML is great for rendering, but converting it to a JSON AST unlocks much more: you can analyse, transform, store, or re-render the content later in any format you need. Each element (headers, paragraphs, links, images, code blocks, …) is preserved as a node so your application can work with structured data instead of raw strings.

💡 Tip

Choose Pandoc when you need the richest AST, Remark when you are in the React / unified ecosystem, or markdown-it when you just need fast tokenisation.

Quick Start

4 Easy Steps

1
Select an Input Method

Switch between "Text Input" and "File Upload". You can paste Markdown directly or drag-and-drop a .md file.

2
Pick a Conversion Engine

Open the settings dropdown (⚙︎) and choose Pandoc, Remark or markdown-it. You can also toggle pretty-printed JSON.

3
Inspect the Live AST

The JSON AST refreshes automatically as you type or replace the file – no extra clicks required.

4
Copy / Download

Use the "Copy" button to put the JSON on your clipboard or "Download" to save a .json file locally.

What Does the Output Look Like?

The exact top-level keys depend on the engine you choose:

Pandoc

  • blocks – All block-level nodes
  • meta – Document metadata
  • pandoc-api-version – Removed automatically when pretty-print is enabled

Remark

  • type – Always "root"
  • children – Array of mdast nodes

markdown-it

  • [] – Flat array of tokens, each holding type, tag, nesting and more

Example Conversion (Pandoc AST)

From Markdown → Pandoc JSON

Markdown Input:
# Hello World

This is **Markdown**.
JSON Output (abridged):
{
  "blocks": [
    {
      "t": "Header",
      "c": [
        1,
        ["hello-world", [], []],
        [{"t": "Str", "c": "Hello"}, {"t": "Space"}, {"t": "Str", "c": "World"}]
      ]
    },
    {
      "t": "Para",
      "c": [
        {"t": "Str", "c": "This"},
        {"t": "Space"},
        {"t": "Strong", "c": [{"t": "Str", "c": "Markdown"}]},
        {"t": "Str", "c": "."}
      ]
    }
  ],
  "meta": {}
}

Best Practices

Keep a Consistent Heading Hierarchy

A logical heading structure (H1 → H2 → H3 …) makes the AST easier to analyse and transform later.

Enable Pretty Print for Debugging

In the settings dropdown you can toggle pretty-printed JSON. This removes the Pandoc API version and indents the output for easier reading.

Keep Code Block Languages

Specifying the language (e.g. ```js) lets parsers include the information in the AST which later helps with syntax highlighting or executability.
