JsonToTable: JSON to Table

If you've ever stared at a wall of JSON from some API and wished you could just see it as a table — that's what this does.

How the conversion works

Give it an array of objects and you get a proper table: each object is a row, and every unique key across the array becomes a column. Missing keys just show up as empty cells, so you don't have to worry about objects with slightly different shapes.

Give it a single object and you get a two-column key and value table.

When values are themselves objects or arrays, they don't get flattened or stringified. They render as nested tables inside the cell. So a deeply nested API response stays browseable and you can actually see the shape of the data instead of scrolling through curly braces and square brackets.

Arrays of primitives like strings, numbers, or booleans are shown inline, comma-separated, so you don't end up with pointless one-column tables.

If the JSON is broken, you get a clear message pointing to the line and column where parsing failed, not a cryptic Unexpected token dump.

Three ways to feed it JSON

Click the toolbar icon, paste your JSON in the popup, and you see the table right away.

Select JSON anywhere on a webpage, right-click, and pick Convert selection to JSON table. It opens in a new tab.

Or just visit an API URL that returns raw JSON in the browser. A small View as Table button shows up so you can flip between raw text and table view.

A few things worth knowing

Everything runs locally. No servers, no logging, no tracking, no accounts. Your JSON stays on your machine.

Works with any valid JSON, whether that's a small snippet, a deeply nested structure, a large API response, or mixed types.

Null and undefined values show up as a dim dash so you can spot gaps at a glance.
