JSON to Markdown Converter – Convert JSON to MD Online

Convert JSON to Markdown (MD) – Free Online Tool

Instantly convert JSON objects into Markdown tables or lists. A free tool for generating documentation, README files, and static site content.

How to Convert JSON to Markdown

Creating Markdown tables manually is tedious and error-prone. This tool automates the process instantly. Here is how:

  • Step 1: Copy your JSON data (preferably an array of objects for tables).
  • Step 2: Paste it into the input editor above.
  • Step 3: Click “Convert to Markdown”.
  • Step 4: Copy the generated code directly into your `README.md` or `.mdx` file.
💡 Smart Detection: If you provide an Array `[…]`, we generate a Markdown Table. If you provide a single Object `{…}`, we generate a Bullet List.

When to Use This Tool

Markdown is the language of the web’s documentation. You need this converter when:

  • Documentation: Converting API response examples into readable tables for your docs.
  • Open Source: Generating status tables or configuration options for GitHub/GitLab README files.
  • Static Sites: moving data from a headless CMS (JSON) into Hugo, Jekyll, or Gatsby markdown files.
  • Logging: Turning JSON logs into readable notes for bug reports.

Why Use Our JSON to Markdown Converter?

1. Privacy-First & Secure

Documentation often includes internal API endpoints or configuration keys. Unlike server-side tools, this converter runs 100% in your browser. Your data never leaves your device.

2. Auto-Formatting Tables

Aligning Markdown table columns manually requires counting spaces. Our engine handles:

  • Header Alignment: Automatically creates the separator row `|—|—|`.
  • Missing Data: Fills empty cells if some objects in the array are missing keys.
  • Escaping: Escapes pipe characters `|` inside your content so the table doesn’t break.

3. Offline Capability

Once loaded, this tool works without an internet connection, allowing you to work on documentation while offline or on an airplane.

JSON vs. Markdown: The Data vs. Presentation

Understanding the difference helps you choose the right format.

JSON (Data)

JSON is for machines. It is structured, hierarchical, and strict. It is perfect for APIs but hard for humans to scan quickly when raw.

Markdown (Presentation)

Markdown is for humans. It converts plain text into HTML. Markdown Tables are a popular feature (GitHub Flavored Markdown) to present structured data like JSON arrays in a readable grid.

Frequently Asked Questions

Does it support nested objects in tables?

Markdown tables are flat. If your JSON contains nested objects, this tool will stringify them (e.g., `{“id”: 1}`) to fit inside a single table cell.

What Markdown flavor is this?

We generate GitHub Flavored Markdown (GFM) tables, which are supported by GitHub, GitLab, Reddit, and most static site generators.

Can I convert Markdown back to JSON?

Not with this tool. Converting Markdown back to structured JSON is complex because Markdown lacks strict data types (everything is text).
