What is JSON to HTML Converter?

Embedding JSON data in a web page usually means rendering it as a table, a list, or a set of cards. Doing it by hand is straightforward but tedious. This tool renders any JSON value into one of three HTML layouts and gives you the source code to copy.

Table mode is the most useful: when the input is an array of objects, the tool detects every distinct key across the array and produces a column for each, with one row per item. Missing keys produce empty cells. For non-uniform structures, the table degrades into a two-column key/value layout. Nested list mode produces a fully recursive `<ul>` representation, and cards mode renders one styled card per array item.

How to Use JSON to HTML Converter

1

Paste JSON into the input panel.

2

Pick a display mode: Table, Nested list, or Cards.

3

Optionally set a CSS class for the outer table.

4

Toggle inline styles if you want the preview to look styled without a stylesheet.

5

Copy the generated HTML.

Common Use Cases

  • Embedding API response data into a static HTML page.
  • Generating HTML tables for a quick admin or debug page.
  • Producing card layouts from a list of objects.
  • Visualizing nested JSON as a readable bullet list in documentation.

Example Input and Output

An array of objects becomes an HTML table with one column per key.

JSON input
[
  { "id": 1, "name": "Alice" },
  { "id": 2, "name": "Bob" }
]
HTML output
<table><thead><tr><th>id</th><th>name</th></tr></thead><tbody><tr><td>1</td><td>Alice</td></tr><tr><td>2</td><td>Bob</td></tr></tbody></table>

Privacy

All conversion happens in your browser. No JSON is sent to a server.

Styling

The optional <style> block uses a neutral palette. For production use, remove the style block and target your custom class through your application stylesheet.

Frequently Asked Questions

What happens if my array of objects has different keys?

The tool collects all keys across all objects and creates one column per unique key. Missing keys produce empty cells.

Are HTML special characters escaped?

Yes. All values are HTML-escaped before being inserted, so JSON containing < or & cannot break the output or introduce XSS.

How are nested objects in a table rendered?

Nested objects become a small inner table inside their cell. Arrays inside arrays render the same way recursively.

Does this send my JSON anywhere?

No. All rendering happens locally in your browser.
