Operis Analysis Kit (OAK)

The award-winning spreadsheet modelling Excel add-in.

OAK is the world's leading tool used to review and develop complex spreadsheets.

The Operis Analysis Kit, otherwise known as OAK, is an Excel add-in that saves time when developing and auditing complex spreadsheets by assessing the model structure and identifying errors.

As a company, we believe it is crucial to support spreadsheet users. That’s why we decided to share what once was our in-house application with our clients.

Developed and used daily by our renowned modelling team, OAK helps identifying the lack of compliance with industry-standard modelling best-practices. It also improves model quality throughout the building process.

OAK is the preferred Excel add-in used by financial modellers in the world’s largest banks, blue-chip firms and public sector bodies.

If you are currently using Operis’ other services please get in touch about adding an OAK license to your current package.
