I came across a problem last week when a client wanted to use Microsoft Word to perform a mail merge to individual documents. By default Microsoft Word allows you to merge to a single Word document or merge directly to the printer. This works well if you’re working with Address labels or similar document structures. However, instead of saving 100 letters to 1 document what if you wanted to save 100 letters as 100 different documents?
