Have the person with Excel try the following.
1. Open Microsoft Excel.
2. Click on the "File" drop-down menu, and select "Open," or click on the "Open" button that looks like a file folder in the toolbars. In the dialogue box that comes up, select "All Documents." Selecting just "All Word Documents" may hide the Works documents.
3. Find and select the Works document that you want to convert to Excel. Click "OK." The document will then open in Excel.
4. Save the document as an .XLS file, that is, as an Excel workbook. In other words, open the "File" drop-down menu again and select "Save As..." Then select "Excel Workbook" for the format option. If a dialogue box asks if you really want to convert it, answer "Yes."
Please respond and let us know the status of the issue.
