JSON to Markdown Converter
Convert JSON to a Markdown table or bullet outline online. Arrays of objects become pipe tables with escaped cells and aligned numeric columns.
What is the JSON to Markdown Converter?
The ByteTools JSON to Markdown Converter turns JSON into ready-to-paste Markdown. An array of objects becomes a pipe table: the union of all keys forms the header row, numeric columns are right-aligned, and cell content is escaped so pipes and line breaks cannot break the layout.
- Arrays of objects become GitHub-flavored pipe tables
- Header row built from the union of all object keys
- Numeric columns right-aligned automatically
- Pipes and newlines escaped so cells never break the table
- Bullet outline mode for nested objects and mixed data
- 100% private — JSON never leaves your browser

About the JSON to Markdown Converter
The ByteTools JSON to Markdown Converter turns JSON into ready-to-paste Markdown. An array of objects becomes a pipe table: the union of all keys forms the header row, numeric columns are right-aligned, and cell content is escaped so pipes and line breaks cannot break the layout. Nested objects and any other JSON become a clean bullet outline with bolded keys.
It is handy for dropping API data into a README, GitHub issue, pull-request description, wiki page or static-site post without hand-building table syntax. Auto mode picks the right format for your data, or you can force table or outline mode explicitly.
Conversion happens 100% locally in your browser using JavaScript. The JSON you paste is never uploaded or stored, so internal data and reports remain private.
Frequently asked questions
How do I convert JSON to a Markdown table?
Paste a JSON array of objects and click Convert to Markdown. Each object becomes a row and every key that appears in any object becomes a column, with missing values left as empty cells.
What happens if my objects have different keys?
The header is the union of all keys in order of first appearance. Rows that lack a key simply get an empty cell, so ragged data still produces a valid, rectangular table.
How are special characters inside cells handled?
Pipe characters are escaped as \| and newlines are converted to <br>, because a raw pipe or line break would split the cell. Nested objects or arrays inside a cell are rendered as inline JSON.
Can I convert a nested object rather than an array?
Yes — use outline mode (or Auto, which picks it automatically). You get an indented bullet list with bold keys, which reads well in READMEs and issue comments where a table would not fit the shape of the data.
Does the table work on GitHub?
Yes. The output uses standard pipe-table syntax with an alignment row, which renders in GitHub, GitLab, Obsidian, Notion and most other Markdown engines that support tables.
