About

xplo is a tool for running Excel spreadsheets quickly, helping people who build models in excel rapidly explore their models. Upload a spreadsheet, assign probability distributions to input cells, and xplo will run Monte Carlo simulations to show you the range of possible outcomes.

How It Works - Web

1. Upload your Excel file (.xlsx)
2. Select the input cells you want to vary
3. Assign probability distributions (normal, uniform, triangular, etc.) to those cells
4. Run the simulation (in your browser, for free)
5. Explore the output distributions and understand your risks and opportunities

How It Works - API

Through the xplo API you can get access to the same high-quality, high-speed execution, on any computer (laptop, desktop, or server). Read more about this on the API page.

Why xplo?

Spreadsheets are widely used for modeling - across finance, risk analysis, investment, climate and other spheres, Excel is the lingua franca for creating and collaborating on complex numerical models. However Excel is slow, and often requires large workarounds, macros, and beefy machines to run simulations over these models quickly.

xplo allows people the best of both worlds - build and collaborate in excel, then execute, test, and evaluate in xplo.
