From Epsilon Technologies:
Xpertdoc Studio is a reporting tool that allows you to create Microsoft Word customized documents. Our template designer is fully integrated with Microsoft Word, and is complemented by an ActiveX production engine designed for speed and simple integration with your applications. Although it is the ideal solution for mail-merge problems, Xpertdoc Studio is much more than just merging because it also allows you to completely customize the content of the produced documents using VBScript expressions. Due to its open architecture, an Xpertdoc Studio template can be based on several different data sources such as databases (SQL), ASCII files, XML files or any other custom data source.
