You can output your data like this:
Say for instance I am compiling names of people, their birthdates and their ages. I would save the output to a text file, birthdays.csv that looked like this.
John,6/24,28
James,8/19,26
George,5/9,28
...
.csv stands for comma separated values. Microsoft Excel can read these files and places each entry into its own cell. Entries are separated by commas and null characters.
I could explain better but I've got something to look for.
