## What is a JSON Formatter?

A JSON formatter is a tool that takes raw or compact JSON data and transforms it into a
human-readable structure with proper indentation, line breaks, and spacing. It can also
validate your JSON to catch syntax errors such as missing commas, unmatched brackets, or
trailing characters, and minify it by stripping all unnecessary whitespace to produce the
smallest possible output.

Developers frequently need a JSON formatter when working with webhook payloads, API
responses, configuration files, and log output. Raw JSON from an API endpoint or webhook
delivery is often a single compressed line that is nearly impossible to read. Formatting it
instantly reveals the structure of the data, making it far easier to debug issues, verify
field values, and understand nested relationships.

## How to Use

1. **Paste your JSON** — Drop raw JSON from a webhook payload,
    API response, config file, or any other source into the input panel.
2. **Choose a mode** — Select _Format_ to pretty-print with indentation, _Minify_ to compress into a
    single line, or _Validate_ to check for syntax errors.
3. **Get instant results** — The output appears
    immediately in the right panel. Click _Copy_ to grab the result to your clipboard.

## Features

### Real-time Formatting

JSON is formatted as you type. No need to press a button — results update instantly in
the output panel.

### Syntax Error Detection

Pinpoints exactly what went wrong with descriptive error messages including position
information so you can fix issues fast.

### Configurable Indentation

Choose between 2 spaces, 4 spaces, or tabs to match your project's coding style and
preferences.

### One-click Copy

Copy the formatted, minified, or validated output to your clipboard with a single click,
ready to paste anywhere.

## When to Use JSON Formatting

- **Debugging webhook payloads** — Quickly make sense of incoming
webhook data by expanding compressed JSON into a readable structure.
- **Reading API responses** — Format raw API output to inspect
field values, check nested objects, and verify data integrity.
- **Preparing test data** — Validate and format JSON fixtures
before using them in automated tests or manual API calls.
- **Validating configuration files** — Catch syntax errors
in JSON config files before deploying to avoid runtime failures.

## FAQ

### Is my JSON processed server-side?

No, everything runs entirely in your browser. Your JSON data never leaves your machine
and is not sent to any server.

### What's the difference between format and beautify?

They are the same thing. Both operations add proper indentation and line breaks to make
JSON human-readable. The terms are used interchangeably.

### Can I format large JSON files?

Yes, this tool works with any size JSON that fits in your browser's memory. For most use
cases — webhook payloads, API responses, config files — there are no practical limits.
