Hi everyone, I have a quick 'is it possible' question

At my current job we have order info in a database and each week we run a report which extracts something similar to the following into an excel spreadsheet. It shows what each customer has bought

CustomerID Customer Name Order Cost
ABCD1 Acme £200
DEFG Widget £150
ABCD1 Acme £120

Basically, we then generate letters per line using mail merge but this is wasteful if the same customer has made multiple orders. Is there a simple way to get word to recognise multiple orders and create a line in the document for each item ordered? For example, using the data above, the end result would be 1 letter for Acme with two order items inserted instead of 2 seperate letters with one item each. Can anyone suggest a few basic steps for this or even advise how it might be done better (get it in access and use SQL to join then do something else?).

I really dont want to take up too much of anyones time, just wondering if anyone has done this before using VBA code or if it is going to be a nightmare. I have coded Outlook VBA code before so I should be capable of coding something quite nice but advice on a more elegant solution if available would be great.

Cheers
Iain
