Automatic timestamp when a cell is filled out

Question

I have an excel formula that is very simple and it works because I can restrict the recursive iterations. I am not very script savvy, but this is what it is and it works.

Answer 1

Actually, in this case you don't have to script anything. Google (or someone) has done it already. In your Google spreadsheet, go to "Insert -> Script" and search on "time". There are two ready-made scripts which will do what you want. I found "Cell Last Modified Date" works perfectly. Select it and click the "Install" button. You can reformat the column to show date, date+time, and so on. You can also hand code a date in the column, or move them from another column if you were tracking it before, and they will stay as you set them. But updating any cell in the row will update the timestamp.
