JSON to Markdown Table

Markdown Table Syntax

Markdown tables use pipes (|) to separate columns and a row of hyphens (-) to mark the header separator. Writing these by hand for anything beyond a handful of rows is tedious and error-prone — miscount a pipe and the whole table renders broken. This converter takes a JSON array of objects, uses the keys of the first object as column headers, and generates a properly aligned table automatically, including column-width padding so the raw Markdown source is readable even before it's rendered.

| Name  | Role      | Years |
|-------|-----------|-------|
| Alice | Developer | 5     |
| Bob   | Designer  | 3     |

Alignment markers in the separator row control how a renderer justifies each column: :--- for left, :---: for center, and ---: for right. This tool exposes all three as an option instead of defaulting to plain left-alignment.

How to Convert JSON to Markdown

1. Paste your JSON array of objects — every object should share roughly the same keys, since the first object's keys become the table's column headers.
2. Select formatting options: column alignment (left/center/right), bold vs regular headers, and whether nested values should be pretty-printed.
3. Click "Convert to Markdown" to generate the table.
4. Use the live preview to confirm it renders as expected, then copy the Markdown source or download it as a .md file.

Common Use Cases

• API Documentation: Turn a JSON array of endpoint parameters or response fields into a readable reference table for your docs.
• README Files: Generate feature comparison tables, changelogs, or dependency lists directly from structured project data.
• Comparison Tables: Compare pricing tiers, feature flags, or version differences pulled straight from a JSON config or API response.
• Data Reports: Turn query results or analytics exports into shareable tables for a wiki page or pull request description.
• Technical Specs: Document configuration options, environment variables, or CLI flags stored as JSON in your codebase.
