SolverStudio is an add-in for Excel 2007 and 2010 on Windows that allows you to build and solve optimisation models using the Python-based PuLP modelling language. OpenSolver Studio allows you to create and edit your PuLP model without leaving Excel, and to save your model inside your workbook. You can also easily link data on your spreadsheet to Python variables in the model. OpenSolver Studio can run the Python statements in PuLP model which solves the problem and puts the answer back onto the spreadsheet.
