Frequently asked questions
Does deleting hidden sheets satisfy GDPR data minimization requirements?+
Deleting hidden sheets removes the data from the shared file but does not erase it from the original. For full erasure requests, delete data from all source systems.
Can I use this tool in a regulated environment?+
Yes — because processing is entirely browser-local, the file never reaches external servers, satisfying most data residency requirements.
