Frequently Asked Questions

Everything you need to know about Openbox.

What is Openbox?

It is a tool to help professional modellers build, review and explain models much more quickly and reliably than ever before. Eliminate the repetitive, low-value parts of modelling and deliver models to keep up with the deal.

How does the Openbox installation work?

Simply download the file from our website ( and double click it. A standard software installation wizard will guide you through the process. You don’t need to have anything else installed on your computer, except Microsoft Excel.

How does Openbox integrate with Excel?

Openbox links to Excel as an add-in, which means you can access it without ever leaving Excel.

How do I update Openbox?

Open Excel and click “Openbox” in the Ribbon. The button at the far right will check for updates and if one is available, install it.

Can you work on financial models in both Excel & Openbox?

Yes, you can work either in Openbox or in Excel (with some limitations). Openbox will synchronise the Openbox and Excel versions.

How long does the Openbox trial period last?

45 days. The software is fully functional during that time. If you find you need a few more days at the end, please contact us and we’ll be happy to extend the trial.
