Would someone please do me a favour for this task.
I can already get the CSV file row by row.
I would like to compare a incoming CSV file against the SP list items, using the ID_2, and Sequence column are key, if ID_2, Sequence are equal but ID_4 not equal, update ID_4 from CSV file to list, otherwise skip.
The image is a snapshot, I actually have around 10K rows in the CSV, which have similar structure. Thanks.
