Dynamically select columns based on configuration File



I have two Excel Files (Let's call them X and Y). X has 40 columns with 5 rows. (Name of columns are well defined). Y is a 10* 1 table which contains the target column names. I want to output only those columns in X whose names are present in Y. Thank you for your help!

Hello Anand1994,


You can use a union field to unite both files and select in union tool to only 'output common subset of fields' as image attached.

Hope it helps.

You could Transpose the fields from your input, then Join to the lookup table and finally Crosstab the joined records.
