The Operis Analysis Kit is a sophisticated software package that aids spreadsheet users in the development and review of complex financial models.

For over 17 years the Operis Analysis Kit, or OAK, has been a vital aid to spreadsheet users, used by almost all of the large accounting practices and major financial institutions around the world.

It is extensively used by the Operis modelling team and recognised as the industry standard in Excel modelling and auditing software. In June 2020, OAK won a Lifetime Achievement Award at The Financial Modelling Innovation Awards.

OAK provides more than 30 tools including these four key functions:

– Summarize – Generates reports on the model’s complexity as well as modelling risk factors.
– Map – Provides a visual representation of the model’s formula consistency.
– Search – Locates cells with specific attributes.
– Compare – Indicates what has changed from one version to another of a workbook/worksheet/range.

The fifth-generation version of the software, OAK5, is now available offering cutting-edge tools to help increase productivity and efficiency.

You can download and install OAK on a computer to trial for FREE for 15-days in its full unrestricted version.
