Frequently Asked Questions
Are my files or text uploaded to a remote server?
No. All computation occurs 100% client-side in your browser JavaScript thread. No payload data is ever transmitted across the network.
Does CSV to JSON use advertising or behavioral trackers?
Never. OTHRYS tools have zero tracking pixels, zero analytics scripts, and set zero third-party cookies.
Can I use this tool offline?
Yes! Once loaded, CSV to JSON executes without any network dependency. You can safely disconnect your internet connection and keep using it.
