I have a spreadsheet with about 600 rows and 20 columns.
I want to add a unique identifier to each cell so that I can use the exported CSV output in another app.
So I thought that I could add a column after each existing column, and then use a formula to populate the cells.
So, first, are there better ways to do this? and if not, is there a short cut to adding 20 new columns?
Thanks

To add a new column right after the existing column:
Repeat for each existing column to create a new blank column on their right.
To create 20 new column at once:
This one will create 20 blank column right after the existing column. You need to rearrange them later.
