I am quite new to ArcMap. I want to add a column of a .csv file to the end of the attribute table of a feature class. The column and the attribute table are of the same length. I tried to use the "append" tool. First I copied and pasted the target column of my .csv file into a blank Excel spreadsheet and saved it as a new .csv file. I then added this to ArcMap. When I try to append this to my target attribute table using the "append" tool I get the following error message:

"ERROR 000338: Inputs must be either all Feature Classes, Tables or Rasters; not mixed."

enter image description here

This is confusing because I only have one input dataset, so I'm not sure where the "mixed" warning comes from...

    Append adds to the length of a table, not the width. You want to Add Field, Join, and Calculate Field. – Vince Nov 8 at 13:17
  • Aha, thanks for the correction! Could you please elaborate a little on exactly how I carry out the Add Field, Join and Calculate Field steps? Many thanks – biogeo Nov 8 at 14:01
  • OK I have managed to get the required output I want but I am sure there must be a simpler solution so I am posting what I did here in the hope someone can shed light on this. – biogeo 16 hours ago
