JSON Inspector

Check a JSON payload before it reaches an API boundary. Format or minify valid JSON, inspect its top-level shape, and get a parser error with a line and column when the runtime provides a position.

WHY THIS TOOL EXISTS

A focused job, not a black box.

A quick review surface for payloads that are hard to read in one line. The output reports the JSON value type and direct member count so you can catch an unexpectedly empty object or array.

How to use it

Paste a JSON value or load the sample.
Choose readable or compact output.
Review the shape summary and copy or download the result.

TRY A WORKING EXAMPLE

Start with known input.

Load this sample into the workspace, run the tool, and compare the result shown below.

Show sample input

{
  "source": "{\"service\":\"billing\",\"enabled\":true,\"regions\":[\"eu-west\",\"us-east\"]}",
  "mode": "Readable"
}

LIMITS AND INTERPRETATION

What the result cannot tell you.

This checks JSON syntax and the visible top-level shape. It does not validate an API schema, infer business meaning, or repair malformed input automatically.
