Frequently Asked Questions

What is a JSON Formatter?

A JSON Formatter is a tool that helps you beautify, structure, and validate your JSON data. It transforms messy or minified JSON code into a human-readable format with proper indentation and line breaks, making it easier to read, debug, and understand.

How do I validate my JSON?

Simply paste your JSON into the editor and our tool will automatically validate it in real-time. Any syntax errors will be highlighted with detailed error messages and line numbers to help you fix issues quickly.

Is this JSON validator safe to use?

Absolutely. All JSON processing happens locally in your browser. Your data is never sent to our servers, ensuring your information remains private and secure.

What happens to my data?

Your JSON data never leaves your browser. All processing, validation, and formatting happens locally on your device. We don't store, transmit, or have access to any of your data, ensuring complete privacy.

What file formats are supported?

Our tool supports standard JSON (.json), JSON5 (.json5), and JSONC (JSON with Comments). You can paste content directly or upload files. The tool automatically detects the format and applies appropriate parsing rules.

Are there keyboard shortcuts available?

Yes! Use Ctrl+S (Cmd+S on Mac) to format JSON, Ctrl+A to select all, and standard editing shortcuts. The editor supports most common code editor shortcuts for efficient JSON editing.

What are common JSON syntax errors?

Common errors include: missing commas between properties, trailing commas (not allowed in standard JSON), unescaped quotes in strings, missing closing brackets/braces, and invalid characters. Our validator highlights these with specific error messages.

What is JSON5?

JSON5 is a superset of JSON that aims to make it easier for humans to write and maintain by hand. It includes some features from ECMAScript 5, such as comments, trailing commas, and unquoted object keys. Our tool's support for JSON5 gives you more flexibility when working with different data sources.
