VBScript to Combine Multiple XLS Files into a Single File

Here's a companion tip to the "VBScript to convert CSV to XLS" post.

This script will combine two Excels files into one workbook. The files will be treated as separate worksheets inside the workbook. The worksheet names will be the same as the file names.

You may find this useful when an Inforamtica process outputs multiple flat files and you have converted them into native Excel format but only wish to present one file to the end user (or for archiving or reporting purposes).
