Can I make csv file in columns?

Hi Transportr,
We're upgrading our theme and the collections and product urls will be changing - I want to prep the .csv file to upload all the redirects - silly questions - can I have path and target in two separate columns and upload this rather than have to separate path and target by a comma? - It's going to be quicker for me to compile the csv if I can copy paste the target url into a new column rather than add it to each row after the path individually - I'm probably missing something here - please enlighten me.
Thanks
Heather
