Frequently Asked Questions
Does minifying change JSON data?
No. It only removes whitespace and line breaks, keeping keys and values intact.
What if JSON is invalid?
Fix the JSON syntax first. Use a JSON formatter/validator to locate errors.
Is minified JSON good for production?
Yes. It reduces payload size but is less readable for humans, which is fine for machines.
Is my data uploaded?
Most tools run locally in your browser. For tools that require network requests, the UI will indicate it.
