How Do I Add Commas To Columns And Remove Spaces In Excel??

I need to create lists with the use of 3 columns, i.e., first name, last
name, date
so that it ends up like below when I select all three columns and then copy
and
paste to a text editor like Word Pad ...

first-name,last-name,date
first-name,last-name,date
first-name,last-name,date
first-name,last-name,date


Thank You!
