How to choose what excel column to write to in excel using iqbot to extract pdf invoices?

I have watched a video of using the iQbot for invoice extraction to excel. In the video it shows the person extracting different data from the invoice to the excel columns A to J by default at 25.15 timing in the video below.

How do I define what excel columns I would like the data to be extracted to in excel using the iqbot? like etc for invoice number to be extracted to column M or quantity to be extracted to column R in excel.
