General FAQ
Q Does JSON Utility Kit store my data on a server?
No. JSON Utility Kit processes all formatting, validation, editing, and conversion entirely client-side on your local machine using standard JavaScript. Your data never leaves your computer.
Q Are these tools free to use?
Yes! All features on JSON Utility Kit are 100% free, unlimited, and open-access. No subscriptions, logins, or paywalls are required.
Q Can I format very large files?
Yes, because the parsing runs directly in your browser without network overhead. However, pasting extremely large text documents (e.g. over 50MB) may hit standard browser engine memory performance thresholds.
