Frequently Asked Questions
Can the tool validate JSON syntax?
Yes! The JSON formatter automatically validates your JSON and highlights syntax errors with line numbers and descriptive error messages. It helps you quickly identify and fix issues like missing commas, brackets, or quotes.
What's the difference between beautify and minify?
Beautify adds indentation and line breaks to make JSON human-readable and easy to debug. Minify removes all unnecessary whitespace to create the smallest possible file size - ideal for production or API responses.
Can I sort JSON keys alphabetically?
Yes! The tool can automatically sort object keys in alphabetical order, making it easier to compare JSON files, find specific properties, or maintain consistent formatting across your data.
Are there any file size limits?
No limits! Since processing happens entirely in your browser, you can format, validate, and minify JSON files of any size. The only constraint is your device's available memory.
