What is JSON and why does it need formatting?

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write and easy for machines to parse and generate. Formatting JSON makes it more readable by adding proper indentation, line breaks, and spacing, which is especially important for complex or nested JSON structures.

How does the JSON validator work?

Our JSON validator checks if your JSON adheres to the proper syntax rules. It verifies that all opening brackets, braces, and quotes have matching closing ones, that commas are used correctly, and that the overall structure follows JSON specifications. If errors are found, the validator will highlight them and provide helpful error messages.

Can I use this tool for large JSON files?

Yes, our JSON formatter is optimized to handle large JSON files efficiently. The tool processes data directly in your browser without sending it to our servers, ensuring both performance and privacy. For very large files (several MB), you might experience a slight delay during processing.

Is my JSON data secure when using this tool?

Yes, your data remains completely private. All processing happens directly in your browser - your JSON is never sent to our servers. This ensures that sensitive data stays on your device and isn't transmitted over the internet.
