I want to map data from master file and write it in another file as below.
(map row ID from row Type in master file and insert column Type in output file (in column C)
I’m afraid that it doesn’t matter to much on how many rows are in master.
It depends a lot by how many rows are within the input files (here you have the For Each Row loop).
I’ve tested a similar workflow read range(1 row input + a master file of 12000+ rows) & lookup data table and it took 3 seconds to return the searched value.
I’m afraid that the issue either with the HW or SW resources or somewhere else within your workflow
