The objective function is what we’re trying to minimize, which in our case is an Excel formula. Where X is the initial value of the inputs to the objective function. To do the equivalent of Excel’s Goal Seek in Python, we would do something like: from scipy.optimize import minimize minimize(objective_func, X) With Python running in Excel, we can now use scipy.optimize directly from within Excel. PyXLL allows you to write worksheet functions (UDFs), Excel Macros, menus functions, ribbon toolbars, RTD functions and more all using nothing but Python - no VBA required. There is no need to choose between the interactivity of Excel and the power and productivity of Python as you can integrate Python into Excel, and even use Python as a complete replacement for VBA. If you’re an Excel user and you want to use Python as a back-end to your workbooks, or if you’re a Python user and you want to use Excel as a front-end for your Python code, you can use PyXLL, the Python Excel Add-In.

If you are new to Python and want to learn you can download the free e-book “The Ultimate Python Guide for VBA Developers™” here: However, if your model is already in Excel, or you prefer to stay in Excel, it is still possible to leverage the scipy.optimize functions from within Excel. Using scipy.optimize is a great solution if your model can easily be re-written in Python. Python is many data scientists go-to tool, and for good reason! For optimization problems that go beyond the simple “Goal Seek” or “Solver” solutions found in Excel, the Python package scipy.optimize offers a more comprehensive array of algorithms.
What if this still isn’t enough though? For more complex problems like global optimization or large scale optimizations, the default algorithms in the “Solver” add-in may not be sufficient. This is like “Goal Seek” on steroids! It can handle multivariate functions, constraints, and has multiple optimization algorithms to choose from. There is the more sophisticated “Solver” add-in that also comes as part of Excel. It can only solve for a single input cell, and there are no controls over the algorithm used. The standard “Goal Seek” feature while useful in many situations is somewhat limited. Given a formula, it will calculate what the input needs to be in order for that formula to equal a specific result. Microsoft Excel has a great feature, “Goal Seek”, under the Data / What If… menu.
Solving has been artifically slowed down for visualization.
