Build financial models in hours, not weeks.

Build better models, in less time, with zero coding error using Openbox.

Openbox is the financial modelling layer for Excel that you’re missing.

Openbox gives you financial modelling superpowers.

Financial models are used to support business-critical decisions. Building and updating financial models in Excel is time-consuming, frustrating and fraught with error. Openbox transforms the process.

  1. Speed up model build | You design the model, specify the components to include, and then fine-tune for your business. Openbox takes care of building the model in Excel. Focus on commercial logic, not model coding.
  2. Work in Openbox or Excel | Start in Openbox and build out to Excel when you’re ready. Make changes in Excel if you want, and Openbox will read them back in.
  3. Quickly export to Power BI | Openbox instantly creates a flat-file of everything in your model. Instantly import your model into PowerBI or other visualisation tools.

How Openbox works

Transform your financial modelling workflow.


Import frequently used components. Connect to external data sources. Preview in Excel at any time.


When you’re ready, Openbox builds out the full model in Excel. Share your model with anybody; they don’t need Openbox to read or use your model.


Openbox checks your model for common errors and helps you fix them. Build in best practice from the start.


Update your financial models between Openbox and Excel simultaneously. Openbox synchronizes changes made between the two.
