Frequently Asked Questions
What happens if my JSON has syntax errors?
+The tool will detect and display detailed error messages showing exactly where the problem is located, including line and character position. This helps you quickly identify and fix JSON syntax issues like missing commas, brackets, or quotes.
What's the difference between formatting and minifying JSON?
+Formatting (beautifying) adds proper indentation, line breaks, and spacing to make JSON human-readable. Minifying removes all unnecessary whitespace to create the smallest possible file size, which is ideal for production use or data transmission.
Can I choose different indentation styles?
+Yes! You can format with 2 spaces, 4 spaces, or tabs for indentation. Each style has its own use case - 2 spaces for compact readability, 4 spaces for better visual hierarchy, and tabs for editor flexibility.
Is there a size limit for JSON data?
+There's no strict limit, but very large JSON files (over 1MB) might take a moment to process. The tool can handle everything from simple objects to complex nested structures with arrays and multiple levels efficiently.
Does the tool support syntax highlighting?
+Yes! The formatted output includes color-coded syntax highlighting that makes it easy to distinguish between keys, strings, numbers, booleans, and null values. This visual formatting helps you quickly understand the JSON structure.
