Another easy process that comes to mind for a really small DB like yours
I have created Excel Templates before for data entry. Excel has the ability to set some fields to Text, number, zip, and so on.
The Excel gets emailed, Access can then import the data.
The data can be either an update, or an addition (append).
Lots of options if you can give us some ideas.
Us old guys got to help each other out. LOL
Happy 2016 New Year - who would have thought back in 1969 we would be here today?
