Frequently asked questions
Why does my JSON fail to format?
Usually a small syntax error - a trailing comma, missing quote, or mismatched bracket. The formatter will point out where parsing failed so you can fix the specific spot rather than searching the whole document.
Is my JSON data sent to a server?
No - formatting and validation happen entirely in your browser; your data is never uploaded anywhere.
What is the difference between formatting and minifying JSON?
Formatting adds indentation and line breaks for human readability; minifying strips all unnecessary whitespace to make the file as small as possible for production use.
