Quick answers

Frequently asked questions

Will JSON minification change the data?

The tool parses and serializes the JSON to remove formatting whitespace. Duplicate keys, comments, and number spelling may not survive that round trip.

Can I minify JSON that contains comments?

No. Comments are not part of standard JSON, so remove them or use a format designed for commented configuration before minifying.
