Do you need someone to help you combine two csv files by some common ID?
Both files must share column with common value (key or ID).
You would like to cobine list of customers (buyers) that contains e-mail addresses and order numbers with database with e-mail addresses and mail addresses (street, city, state). Common key in this case is e-mail address. After combining, you will have new database of your customers with postal addresses and you will be able to send them offer by ordinary mail.
We will join two smaler files for you for just $ 20. For bigger files please send inquiry.
All we need is that you send us two files in csv format. We will do combining for you.
You will pay before we send you back combined files. We will send you sample of merged files before you pay. We will issue Invoice for our services.
