Frequently Asked Questions
Why use this JSON formatter?
This tool instantly formats minified JSON into readable, indented text. It also validates syntax and shows clear error messages if your JSON is invalid. Perfect for developers who need to quickly debug API responses or prepare JSON for documentation.
Is my data safe?
Yes! All processing happens on the server without storing any data. Your JSON is formatted and returned immediately — nothing is logged or saved. You can safely use this for non-sensitive development data.
Does formatting change my JSON data?
No. Formatting only adds or removes whitespace (spaces, newlines, indentation). The actual data — keys, values, arrays, objects — remains exactly the same. Minifying and formatting are reversible operations that don't alter content.
