Thread: How do I populate input fields from text file?

When I browse a 'txt' file and click on upload, it appears in an iFrame below. How do I extract that values below and populate it in the blank spaces above?
eg. (Apple instead of Q1; 31 instead of Fill in Value)

I was told to use something like strings. Can someone please elaborate more?
