How can I import an Excel Spreadsheet with Listmaker to create a new list on the dialer?
Excel Spreadsheet files or .xls files can only be opened with Microsoft Excel. So you must convert the file to either a .csv (Comma Separated Values) or text file. You can do this with Excel but remember that unless you have installed Microsoft Excel on the dialer, you will not be able to even open .xls files there. You will have to open the file on a machine which has Excel and then save the file again but change the Files of Type option that is right below where you name the file, to either CSV or text. This will create a new file that is in a format that is generic and can be imported with Listmaker on the dialer.
