* Your data is processed entirely in the browser and never sent anywhere.
광고
The JSON formatter takes messy or minified JSON text and either indents it for readability or strips whitespace to compress it. Useful for reviewing API responses or cleaning up config files.
Two directions: formatting and minifying
Indenting makes the structure easy to scan at a glance, which helps with debugging, while stripping whitespace to minify reduces file size, which helps with transfer or storage.
Frequently Asked Questions
Does it flag syntax errors?
Yes — entering invalid JSON shows an error indicating roughly where the problem is.
Can it handle large JSON files?
Since it's processed in browser memory, most API response or config file sizes are handled without issue.
