Paste a JSON document and a path, and this tool returns exactly the value at that location — a string, number, object or array. It understands both dot notation (a.b.c) and bracket notation (a["b"][0]), including negative array indexes. Everything runs in your browser.

How to use

  1. Paste your JSON into the first box.
  2. Type a path such as users[0].name in the path box.
  3. Read or copy the extracted value below.

How it works

The JSON is parsed once into an in-memory value. Your path is broken into a list of steps — object keys and array indexes — accepting dot notation, bracketed keys in quotes, and numeric indexes (including negatives that count from the end). The tool then walks the value step by step. If a step is missing it reports that nothing was found, instead of guessing.

A path made of keys and indexes walks down into a JSON tree to reach one value.users[0].nameusers[0]"Ann"

Features

Dot & bracket paths

Mix a.b.c with ["key"] and [0] freely, just like in code.

Negative indexes

Use [-1] to grab the last element of an array.

Shows the type

See whether the result is a string, number, object or array.

Fully private

Your JSON is parsed in your browser and never uploaded.

When to use it

API responses

Pull one field out of a large API payload quickly.

Config files

Check the value at a specific key deep in a config.

Debugging

Confirm what a nested path actually contains.

Learning

Practice how JSON paths map to nested data.

Notes

  • A leading $ or dot in the path is optional and ignored.
  • Keys with special characters work in bracket form: ["a-b"].
  • An empty path returns the whole document.
  • All parsing runs on your device; nothing is uploaded.

FAQ

What path syntax is supported?
Dot notation (a.b.c), bracketed keys (a["b"]) and array indexes (a[0]), which can be combined.
Can I read the last array item?
Yes. Use a negative index like items[-1] to count from the end.
What if the path doesn't exist?
The tool clearly reports that no value was found rather than returning something misleading.
Does it return objects too?
Yes. If the path points to an object or array, it is shown as formatted JSON.
Is my JSON uploaded?
No. Parsing happens entirely in your browser and nothing leaves your device.
