For loop with excel

Hi, I am working on exporting a list of values into an Excel spreadsheet one at a time and then retrieving the output back into a list. This is a very simplified spreadsheet which adds 6 to the input value and returns the sum. (I hope to use this on a more complex task). I was able to get this to work for a single value but when I tried this for a list of values in a for loop I get error. Any thought how to fix this?

I suggest , you should try LunchBox or might be some others packages associate with Excel .

Solved it another way.
