SolverStudio is an add-in for Excel 2007 and later on Windows that allows you to build and solve optimisation models in Excel using any of the following optimisation modelling languages:
- PuLP, an open-source Python-based COIN-OR modelling language developed by Stu Mitchell. PuLP is included with SolverStudio.
- COOPR/Pyomo, an open source COIN-OR modelling language for Python which extends Pulp with abstract models, support for stochastic programming, and a larger range of solvers.
- AMPL, a commercial modelling language. SolverStudio either requires AMPL to be installed by the user, or can install a free trial version of AMPL that allows up to 300 variables and 300 constraints. We have a tutorial on using AMPL with SolverStudio.
We also support running AMPL models in the cloud using the excellent NEOS server; see AMPL on NEOS.
- GMPL (GNU MathProg Language), an open source AMPL look-alike developed as part of GLPK (GNU Linear Programming Kit). GMPL is included with SolverStudio.
- GAMS, a commercial modelling language. SolverStudio requires GAMS to be installed by the user. GAMS provide a free trial version. Support for solving GAMS models using the NEOS server is working in our new beta version.
- Gurobi, a commercial solver which can be accessed from SolverStudio using the Gurobi Python modelling interface. This requires the Gurobi solver be installed. SolverStudio provides a license manager to help manage Gurobi licenses.
- CMPL, an open source COIN-OR modelling language that also includes a remote server for solving on external computers. Also available from Python.
- SimPy, an open source Python simulation language, which is now included with the SolverStudio download.
- Any other Python software that runs under either IronPython or standard Python (i.e ‘CPython‘). IronPython comes built in, while the user needs to install their own choice of CPython.
- We hope to add Zimpl in the near future, and allow GMPL to be used with CBC.
SolverStudio allows you to create and edit your optimisation model without leaving Excel, and to save your model inside your workbook. You can also easily link data on your spreadsheet to sets, parameters, constants and variables used in the model. SolverStudio can run the model to solve the problem and then put the answer back onto the spreadsheet.

SolverStudio is written in VBA, and C# using Visual Studio 2010 Professional. It uses the Microsoft VSTO (Visual Studio Tools for Office) system running on .Net 4 to manage the integration with Excel. It includes IronPython as its embedded Python engine.
