I'll first describe my business background before talking about my difficulty.
I need to automate an Excel credit simulator that determines the gross amount of credit using the Goal Seek function. I only need to automate the calculation of the gross amount, and in order to do so, I need the Goal Seek function of Excel in C# or JS. Because of this, I'm asking you for an algorithm, library, or piece of code that will help me automate this calculation.
Although there isn't much instruction on how to utilize this library, use TridentGoalSeek.
