Read a nested value using an RFC 6901 pointer and inspect its children.

[Open this tool](https://whatson.pk/developer-json-pointer-calculator/)

Category: Developer & Data

A nested value needs an exact path when several parts of a JSON document use similar names.

Enter the document and a pointer, then inspect the located value and children.

## Inputs and controls

* JSON input
* JSON pointer. Empty pointer selects the root. Use ~1 for slash and ~0 for tilde.

## How to use

* Paste or enter JSON input.

* Enter JSON pointer.

* Select Process input. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.


## Why use this tool

Pointer tokens give a precise location rather than relying on a broad text search.


## Before relying on the result

Array indexes start at zero. Escape slashes and tildes using the pointer token conventions.

## Questions

### Do array positions start at one?

No. Array indexes start at zero. Escape slashes and tildes using the pointer token conventions.

### What should I check before using JSON Pointer Explorer?

Check JSON input and JSON pointer. Use the exact units shown beside the controls and replace any example values with your own inputs.
