How to convert JSON to an HTML table
Three steps from JSON to markup you can paste into any page.
1. Paste JSON
Paste an array of objects, a 2D array, a keyed object or JSONLines, or drop a .json file.
2. Edit in the grid
Fix values, reorder columns, add rows. The output updates in real time as you edit the spreadsheet.
3. Copy the HTML
Copy the table element or download it as a file. Your data never left your browser.

Frequently asked questions
Is this JSON to HTML converter free?
Yes. No account, no sign-up, no watermark. Open the page and start converting.
Is my data private?
Yes. Everything runs in your browser. Your JSON is read and processed on your device. Nothing is uploaded, nothing is logged.
Which JSON input shapes are accepted?
An array of objects (most common), a 2D array, a keyed object, and JSONLines (one JSON object per line). The tool detects the shape automatically.
What HTML output options are available?
You can toggle thead/tbody wrappers, HTML entity escaping (recommended to prevent XSS), minification, and add a custom CSS class to the table element.
How are nested objects handled?
Nested objects and arrays are serialized to a JSON string inside the cell, so no data is lost. Flatten them in the grid if you prefer separate columns.
Can I embed this converter in my own app?
Yes. The engine that powers this page is the TabularJS JavaScript library. You can embed it in React, Vue, Angular or plain JavaScript.
