## Overview

The JSON Patch tool allows you to precisely modify, update, or transform JSON documents by applying a sequence of operations defined by the RFC 6902 standard.

## Inputs

- **Original JSON** (textarea): {"name": "John", "age": 30, "hobbies": \["reading"\]}
- **Patch Operations** (textarea): \[{"op": "replace", "path": "/age", "value": 31}\]

## When to use

- When you need to apply specific, programmatic changes to a large JSON object without rewriting the entire file.
- When you are working with API responses and need to test how specific updates affect the data structure.
- When you want to maintain a clean, version-controlled history of changes to your configuration files.

## How it works

- Paste your original JSON document into the 'Original JSON' input field.
- Define your modifications using the standard JSON Patch format (RFC 6902) in the 'Patch Operations' field.
- Click the process button to apply the operations and generate the updated JSON output.

## Use cases

- Updating specific configuration values in a large JSON settings file.
- Removing deprecated fields from a legacy API response structure.
- Adding new items to an existing array within a JSON data object.

## Frequently asked questions

### Which operations are supported?

The tool supports all standard RFC 6902 operations, including add, remove, replace, move, copy, and test.

### Can I apply multiple operations at once?

Yes, you can provide an array of operations in the 'Patch Operations' field to perform multiple edits in a single pass.
