Hi mkonanki,
I had the same issue, on the other thread I posted a solution that will work for this.https://portal.blueprism.com/forums/tech-chat/general-tech-discussion/notepad-excel-copying-data
Problem I had
If you try and import a text file into a collection you'll end up with a single column collection.
Fix I went with
If you open the .txt file as a .xlsx and copy paste that into anothe exce lfile, it will put them into different columns. Import that into a collection.
Alternate method
Another thing you can try is importing the text file int oa colelction, then for each row (single text field) you can separate the text into an array separated by spaces usign the object 'Utility - Strings' action 'Split Text'. Useful for separating A name into a first name and second name. Problem here is if some of the fields are empty then the collection will be out of sync.
