I want to append rows in a CSV file based on content and criteria in a table, eg.
Original CSV:
Name. Class.
John. 3B
Mary 4C
Mary. 3B
Table
Name. Class. Number
Mary. 4C. 2325
So that new CSV is:
Name. Class. Number
John. 3B
Mary 4C. 2325
Mary. 3B
How to add a new column in the CSV file base on criteria from a table?

hi @anguslou ,
I’d configure the following setup:
- csv reader and writer point to the selected file (Local File Browser Config)
- join: left outer join based on Name and Class
- csv writer: mode “overwrite”
I’m sure you won’t be able to append columns to existing rows without reading the file and overwriting it.
Hope that helps, regards, Tommy
