If you have a PC with Microsoft Excel installed just double-click the Excel file (xls suffix) to view the data.
If you have a Macintosh with Microsoft Excel, open Excel first then choose File->Open and point to the text file (txt suffix) and open it.
If you do not have a PC with Microsoft Excel, you can import the data into any other spreadsheet software by running that program and importing the text file (txt).
Once the data has been imported into your spreadsheet software you will need to adjust the width of the columns to see all of the data lined up properly.
