JSON Formatter & Validator

How to Master Your Data with the Professional JSON Tool

JSON (JavaScript Object Notation) is the language of the web, used by everything from servers to mobile apps to structure data. However, raw JSON strings are often messy, unreadable, or full of syntax errors. Our Professional JSON Formatter is designed to solve these problems instantly, giving you a clean workspace to view, edit, and validate your code.

Standard Operations

• Formatting (Beautifying): Paste your raw, clumped-together code into the "Input JSON" box and click Format. The tool will instantly organize your data into a readable tree structure with proper indentation and color-coded syntax highlighting.
• Minifying: If you are a developer preparing data for production, file size matters. Click Minify to strip away all unnecessary whitespace and newlines, compressing your JSON into the smallest possible string.
• Validation: You don't need to click a separate button to check for errors. The tool validates your input automatically. If there is a misplaced comma or a missing bracket, you will see a clear error message in the status bar explaining exactly what went wrong.

AI-Powered Features ✨

We have integrated advanced Artificial Intelligence to help you do things standard formatters cannot:

• Fix Broken JSON: It is frustrating when a single missing quote breaks a 500-line file. Instead of hunting for the error manually, click ✨ Fix JSON. Our AI will analyze the structure, intelligently repair the syntax, and output valid code.
• Explain Data: Encountering a complex configuration file or API response you don't understand? Click ✨ Explain. The AI will read the data and provide a summary of what the file represents and what the key fields mean.
• Generate Data: Need mock data for testing? Click ✨ Generate and simply type a description (e.g., "A list of 5 users with names, emails, and active status"). The tool will create the JSON structure for you from scratch.

Why Use This Tool?

Unlike many server-side tools, our standard formatting runs entirely in your browser, ensuring your data remains private. With the addition of AI assistance, you save time on debugging and data generation, allowing you to focus on building great applications.
