Comment utiliser : JSON to Markdown Table
- Paste a JSON array of objects — or an object that contains one (e.g.
{"data": [...]}). - Columns are collected from all objects; nested objects become dot-notation columns.
- Choose alignment and padding, then copy the Markdown.
Why convert JSON to a Markdown table?
API responses, database exports and LLM outputs usually arrive as JSON arrays. For documentation, README files, pull requests, issue comments or Notion pages, a Markdown table is far easier to read and review. Writing one by hand — pipes, separator rows, alignment colons — is tedious and error-prone, especially when objects don’t all have the same keys.
How the conversion works
- Columns are the union of keys across all objects, in first-seen order; missing values become empty cells.
- Nested objects are flattened (
address.city); arrays and deeper structures are shown as compact JSON. - Alignment: in Auto mode, numeric columns are right-aligned with
---:so figures line up. - Escaping: pipe characters are escaped as
\|and line breaks become<br>, so cells never break the table. - Padding makes the raw Markdown itself readable in code review.

Questions fréquentes
What JSON shapes are supported?
An array of objects works best. An object containing an array (like
{"items": [...]}) is unwrapped automatically, and an array of plain values becomes a single “value” column.How are nested objects handled?
With “Flatten nested objects” on, they become columns like
user.name. Turn it off to show nested objects as JSON in one cell.Is my data uploaded?
No, conversion happens entirely in your browser.
Can I paste JSON from ChatGPT or Claude?
Yes — copy the JSON code block. If it fails to parse because of curly quotes, clean it with the Smart Quotes tool first.
Puis-je installer JSON to Markdown Table en tant qu’application web et l’utiliser hors ligne ?
Oui. JSON to Markdown Table est une application web installable (PWA) : elle s’installe depuis votre navigateur, sans passer par une boutique d’applications.
