xplo - Excel Analysis Tool

Your excel model, lightning fast

xplo makes your spreadsheet run ~1000x faster than in Excel — so you can run millions of simulations for free, on your browser or on the command line — then do anything with the data: explore, export, or share it.

Try Free — Upload Your Spreadsheet

Yep, xplo handles that

Whatever your spreadsheet can do, xplo can too.

A spreadsheet with 100K cells?

Yep. A 100k cell sheet can run up to 180x per second. Smaller models can run up to 30,000x per second.

But I need specialized hardware...

These benchmarks are from a MacBook Air, bigger machines do even better. Runs in any modern browser, and from the CLI on any architecture.

Spilled cells, named ranges, 3D References, volitile formulae?

Yep. And also: type coersion, financial formulae, the 1901 quirk, and even full Lambda support for the Jane Street crowd.

XIRR? BESSELJ? ACCRINTM?

Yep. All 459 deterministic Excel functions — every calling convention, every edge case.

VBA macros?

Yep. Robust support for user-defined functions, with more VBA coverage coming soon.

If your model exposes a bug in our code, we'll buy you a coffee. ☕

We validate by checking computed values against the cached results stored in your .xlsx file — so we know when something's off.

Give it your best shot

Kick the tires with a real-world model

Pick one of these production-grade spreadsheets (kudos to the creators - all external) — we'll download it and open the upload page so you can see xplo in action.

Robust Monte Carlo Simulations

Map any input cell to a probability distribution from any data source or standard model. xplo samples from your distributions, runs simulations, and gives you output data you can download and tools to explore.

Learn how it works

Speed, wherever you need it

After optimization, xplo can run on your browser, or on your machine. Run as many simulations as you want (for free), tinker with inputs, and iterate instantly — it's fast enough to feel like play.

Instant, Unlimited Iteration

Results update in real time as you adjust distributions. No network, no queue, no rate limits, no cost to run your model. It's your hardware!

Run Anywhere

Run in the browser to iterate and collaborate, or run via the xplo CLI or API to supercharge your scripts and workflows.
