Using another excel file

[SarviSarvi]

Hello,

Thank you so much for the tutorial!
When I use another Excel, I get an error (1. Input string was not in a correct format. (line: 0)). I do not know how to fix it.
I refer my x, y, and z values to rows 13, 14, 15.

Hey there,

Input string was not in a correct format is probably coming from the Convert.ToDouble. You need to check if what you are converting actually has a number. maybe there is an entry that has a comma instead of a dot etc..

you can do try catch statment to see what is happening.
