Chapter 2/Exercise 1
This exercise shows how to read a .txt file using the CSV Reader node. The data1.txt file has a header with comments which we don't want to read. The workflow is showing two methods on how to apply advanced file reading features to exclude the comment header from the data:
CSV Reader with "Support short data rows" enabled and "Skip first 5 data rows" in "Limit Rows" tab
CSV Reader with only "Support short data rows" enabled and subsequent Row Filter to remove first 5 spurious rows
It then apply a Column Filter to clean the data and writes it to a .csv file.
