How to bulk change Field Names to unique names?

I have a form where the prepare form form builder just did not work. So instead I created a column of the fields I need and then copy pasted that column multiple times and resized the width of the column fields.  I /thought/ this was giving the pasted  column unique field names.

So now I'm in a situation where I have a hundred fields that all need unique names and I cant figure out how to do that without having to click each one and manually type in a name.   I don't ever really care too much what the name is, just that they are unique so that when I input something into the field it isn't duplicated across the row.
