Frequently Asked Questions

What happens if my JSON is invalid?

The tool displays an error message showing the position and nature of the problem (e.g., missing comma, unexpected token). Fix the issue and try again.

How many spaces for indentation?

You can choose 2, 4, or 8 spaces. 2 spaces is the most common choice for readability and compactness.

Does it support JSON with comments?

No. Standard JSON does not support comments. If your input contains comments, it will be flagged as invalid. Remove comments before formatting.
