Your Excel Logic

Runs Everywhere.

It's simple: you set the value of input cells, and then see how cells change. This computation works anywhere - xplo creates you binaries, CLIs, and APIs so you can run the logic of your spreadsheet wherever you need.

01
For automation

Run it on your machine

Use the logic of your spreadsheets in scripts, scheduled jobs, or local pipelines and receive recalculated outputs.

Unlocking Novel Workflows

What could you do with unlimited excel execution?

Rather than running a few simulations for your report, you can now think in terms of probability distributions. Turn your static workbooks into living, responsive decision tools with xplo's free online workspace.

  • Configure distributions visually
  • Explore sensitivity and outcomes
  • Export the data from every underlying run
