Separating a text string to cells, columns in Excel

I received a string of numbers in an email and needed to manipulate them, so I copied them to a text document and imported the text into Excel 2010 (under the "data" tab, click on Get External Data: From Text). I chose the "Delimited" option instead of the default "Fixed width", clicked "Next", chose "Delimiters: Space" instead of the default "Tab" (note that you can chose multiple delimiter options), clicked "Next", set the column formats, and clicked "Finish".
