What does the type column tell me?

The JSON type of the value, with a size for the containers: `array(3)` has three items, `object(5)` has five keys. That's often the thing you actually need — knowing a field arrived as the string "42" rather than the number 42 explains a whole class of bug.

It walks up to 100 levels deep and 5,000 nodes, and shows the first 500 rows. Those caps exist because the whole document is re-read as you type, and an unbounded walk on a large document would lock the tab. Copy and Download still give you everything that was walked.

Is my JSON sent anywhere?

No. It's parsed by the browser's own JSON parser inside this page. That's the point — the JSON people most need to inspect is usually a live API response containing real data.

JSON Viewer

Paste JSON and see every value in it as a flat list: the path, the type, and the value. This is deliberately not a collapsible tree — the question you usually have about an unfamiliar API response is “what is the path to this field and what type is it”, and a tree makes you click through six levels to answer it. Here every path is written exactly as you would use it in code, ready to copy.

Values only

Hides the object and array rows, leaving just the values you can actually read.

Why use this tool

Every value as a path, a type and a value — no clicking through levels
Paths written in code form, like $.user.roles[0], ready to copy
A values-only mode that hides the structural rows
Reports the exact line and column when the JSON doesn't parse

How it works

1Paste the JSON — an API response, a config file, a log line.
2Switch on “values only” to hide the object and array rows.
3Copy any path straight into your code.

JSON Viewer — frequently asked questions

Because the usual question is “where is this field and what type is it”, and a flat list answers it with one search. A tree hides exactly the thing you're looking for behind however many levels it happens to be nested under. It also means you can copy a working path in one action rather than reading it off the indentation.
