Frequently Asked Questions
Q. Can the tool detect JSON errors?
Yes. If your JSON is invalid, the tool shows an error message pointing out where the issue is.
Q. What is the difference between format and minify?
Formatting adds indentation and line breaks for readability. Minifying removes all whitespace to reduce file size.
Q. Is there a size limit for JSON input?
No. All processing is done in your browser, so there is no server-side size limit.
