Parse Excel to CDT vs Parse CSV Document

Please refer to the below for "Parse Excel to CDT":

Where as "Parse CSV Document" is a smart service ussed to parse CSV files based on the delimiter. Tou need to configure the following details for the CSV parser to work:
"C S V Document","Contains_Header_Row"(True/False),Delimiter and configure the input parameters as col1, col2 etc for each column that you want to retrieve from the CSV file. In the output you can collect the column data by accing the activity class variables(col1,col2).

As "Parse Excel to CDT" parses the data for which the CDT fields are matched with the column name in the excel, I feel that in your case "Parse Excel to CDT" is better option when compare to the "Parse CSV Document".
