Final Fantasy Hacktics

So I am trying to edit my third character slot to make a female with the Holy Knight job and edit some stats, but I am unsure how to work your spreadsheet?  Nothing is loading up in the blank character slate whenever I change something.  Sorry but I am very bad at this stuff and it looked like it was an empty template to create a code from.  Any help would be appreciated. *I have discord and if anyone would be willing to explain to me via voice chat it would probably help immensely.
