I would be grateful for your expert help on the following issue.
Many clients continue to have their customer mailing list in excel format and do their (add / edit / delete) updating of this list offline. We have a simple mailing list application on each of their websites containing just 3 fields Name, Email & Date Joined in an access table.
When they wish to send out their mailing list through the website administration screen, they basically need to have their most up to date version uploaded.
My question is what is the best method to achieve this?
Is their some .asp code out there that can take their .xls spreadsheet, upload to the server and append or overwrite the fields to the access table or does this work need to be done offline and then uploaded?
