It is quite easy, but only if you already know the process. Using the automated "Fill Series" feature in Excel is basically the same as using an AI program since you're simply inputting a command in either one.
For future reference, if you want to know how to do it in Excel (maybe the internet is down!):
1. Insert the starting number (1) in the first cell (A1)
2. Click on the column header (letter A) to highlight the entire column
3. On the home tab, click "Fill" the select "Series"

Click "Ok" and you're done.
Save as a CSV if you want to connect with a VDP program, or CSV if you want a single line of numbers separated by commas.
