add column to .csv file in excel for better overview

Hello everyone,

I want to edit the .csv template downloaded from wix dashboard. For better overview about each → ,
(=comma which samples the code in the row. Sometime , when you don’t need this opportunity)
and its effect for the generated product I want to insert new columns. So every column should have its own opportunity / effect on the generated product.


Example of edited csv file


error message I get when uploaded


Do I have to edit the 1. row. (On wix description there is described this should not be done)

Many thanks in advance!
