We help you make better spreadsheets

Spreadsheet testing

Example of a common formula error

We test spreadsheets, identifying errors and poor practices that create risk.

Our methodology is based on extensive research and practical experience, using sophisticated tools applied by experts.

95% of all spreadsheets contain errors. If your spreadsheets haven't been independently tested, then you cannot trust them to produce reliable, accurate, and robust results.

To find out more about getting an independent test of your important spreadsheets, please contact us.

Training in spreadsheet good practice

Spreadsheet Development Life Cycle

Good spreadsheets are an essential tool for informing decision making. But most spreadsheets are not good.

Spreadsheet training typically shows you how to use the software features, e.g. make a PivotTable.

We have a different focus. We teach you how to make good spreadsheets, maximising usability and minimising risk.

The audience for our spreadsheet training is analysts and managers. Both analysts and managers need to:

  • Understand why spreadsheet good practice matters.
  • Know how to make better spreadsheets.

To find out more about our training options, please contact us.
