Frequently Asked Questions (FAQ)
What does it mean to "beautify" or "format" JSON?
Formatting (or beautifying) JSON means adding line breaks and indentation to the data. This doesn't change the data itself, but it makes the nested structure of objects and arrays much easier for humans to read and understand.
Why would I want to "minify" JSON?
Minifying JSON removes all unnecessary whitespace (like spaces, tabs, and newlines). This makes the file size smaller, which is beneficial for reducing bandwidth and improving loading times when sending data over a network, such as in an API response.
