While adding the text only one problem is there are some pr-efilled cells which I don't want to disturb. I want to add exception that only empty target cells must occupy with text. Moreover it is only adding text having numbering in first column. I want to add text irrespective of text in first column. I Just want to add text to cell totally empty.

I tried but did not get answer to this question. Can I ask again with proper instruction and files?
