## Overview

The JSON Pointer tool allows you to precisely navigate, query, and extract specific data points from complex JSON structures using the RFC 6901 standard.

## Inputs

- **JSON Data** (textarea): {"user": {"name": "John", "age": 30}, "items": \[1, 2, 3\]}
- **JSON Pointer Path** (text): e.g., /user/name or /items/0
- **Operation** (select)

## When to use

- When you need to retrieve a specific value nested deep within a large JSON object.
- When you want to verify the existence of a specific key or path in a data structure.
- When you need to isolate a specific subtree from a larger JSON file for further processing.

## How it works

- Paste your JSON data into the input field.
- Enter the JSON Pointer path (e.g., /user/profile/email) to target the desired location.
- Select your operation: Get Value, Check if Path Exists, or Extract Subtree.
- Execute the tool to view the extracted result or validation status.

## Use cases

- Debugging API responses by quickly pulling specific fields from nested JSON payloads.
- Validating configuration files to ensure required keys exist at specific paths.
- Parsing large data exports by extracting only the relevant sub-sections for analysis.

## Frequently asked questions

### What is a JSON Pointer?

A JSON Pointer is a string syntax defined in RFC 6901 used to identify a specific value within a JSON document.

### How do I reference an array index?

Use the numeric index in the path, such as /items/0 to access the first element of an array named 'items'.

### What happens if the path does not exist?

The tool will return an error or a null result depending on the selected operation, indicating the path could not be resolved.

### Can I extract an entire object using this tool?

Yes, by selecting the 'Extract Subtree' operation, you can pull a nested object or array as a standalone JSON fragment.

### Is this tool compliant with RFC 6901?

Yes, the tool strictly follows the RFC 6901 specification for path navigation and character escaping.
