Online JSON Formatter & Beautifier

What is JSON (JavaScript Object Notation)?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It has become the de facto standard for transmitting data in web applications (e.g., sending data from an API server to the client).

Why use an Online JSON Formatter?

Common Use Cases for JSON Formatters

• Debugging API Responses: When debugging REST APIs or GraphQL endpoints, engineers use JSON formatters to inspect complex, deeply nested response payloads.
• Configuration Files: Many modern tools (like VS Code, ESLint, Prettier) use `.json` configuration files. Our tool helps find missing commas that break the build.
• Web Scraping & Data Extraction: Extracted data often returns as a giant, single-line JSON blob. Formatting it is the first step in data engineering.

How to Format JSON Online (Tutorial)

1. Paste your minified or messy JSON data into the left editor ("JSON Input"). You can also click the paste icon to automatically load data from your clipboard.
2. Select your preferred indentation level (2, 4, 6, or 8 spaces) from the dropdown menu between the editors.
3. Click the Format button to process your code.
4. View the beautified result in the right editor ("Formatted Result"). From here, you can copy the valid JSON back to your clipboard or download it as a .json file.
