## Overview

This JSON viewer renders JSON files locally in your browser. JSON (JavaScript Object Notation) is the standard format for API responses, configuration files, and data interchange. Pick a sample or choose your own .json file to inspect objects, arrays, and nested data in a readable, structured view.

## When to use

- You received a JSON API response or config file and need to inspect it.
- You want a quick formatted preview of minified JSON.
- You are on a device without a code editor and need to browse a .json file.

## How it works

- Select a built-in sample or choose your own .json, .jsonc, or .json5 file.
- The viewer parses the JSON and renders it in a readable view in the browser with no upload.
- Inspect the structure, then switch samples or load another file any time.

## Use cases

- Inspecting API responses and webhook payloads.
- Reviewing package.json, tsconfig, and other config files.
- Browsing large or deeply nested JSON data files.
