That would be a great feature to add to dbFront. I suspect it should not be that hard considering that dbFront already has access to a powerful PDF library but I am not sure.
It would be logical to include that as one of the data import options. Currently, I already support CSV and Excel.
The biggest issue is that PDF forms are not always created with proper internal field names and the field labels are usually inaccessible.
