Batch Processing Fixed Width Text Files to Excel

I have been able to read in a single fixed width text file and convert it into an excel spreadsheet and it works great. I have 40 of these text files that all have the same layout that I would like to batch process so I don't have to do every individual file.

I was thinking I could have two readers one for the file directory and the other for reading in a fixed width text file but that doesn't look like a solution with the reader objects.

Given this use case to read in a directory of fixed width text files what is the best practice to batch these files into the .xlsx now I am able to transform them?
