Reading and analyzing csv data

Hello. I'm super new to NodeRed and I would really appreciate some guidance and help regarding the following:

I have a csv file with 8 columns (the first being the number of the row and the other seven are fields 1 to 7). I would like to read only fields 1, 2 and 5.

Thank you a lot for any suggestion.

As per the info panel you can define a list of column names to set the property names of the incoming data - so you could set something like index,col2,,,col5 and it would only define those in the object it creates.
