Frequently Asked Questions
What does a JSON beautifier do?
A JSON beautifier takes minified, compact, or messy JSON and adds proper indentation, line breaks, and spacing to make it easy to read and understand. It turns a single-line blob into a well-structured, human-readable format.
How is beautifying different from formatting?
They're essentially the same thing. "Beautify" and "prettify" mean adding indentation and line breaks. "Format" is a broader term that can also include minifying. Our tool does both — beautify mode adds spacing, minify mode removes it.
Can I beautify invalid JSON?
No — the JSON must be syntactically valid for beautification to work. If your JSON has errors, the tool will show you exactly where the problem is so you can fix it first.
