Why use Excel-based tooling?

Despite the availability of specialised finance software, spreadsheets continue to play a central role in finance and accounting workflows. Recent research shows that 86 % of financial professionals still rely on Microsoft Excel in their day-to-day work, highlighting the continued relevance of spreadsheet-based solutions in finance functions.  This sustained reliance is not driven by resistance to technology, but by the practical advantages that Excel-based tooling offers in complex financial environments. 

Operate directly on accounting and ERP extracts without complex system integration

Provide full transparency of calculations, assumptions, and data flows 

Allow finance teams to review, validate, and reconcile results independently 

Adapt easily to changes in scope, structure, or accounting treatment 

Fit naturally into existing month-end, quarter-end, and year-end processes

For many finance teams, Excel functions as the environment where accounting data is transformed into actionable financial outputs.

Excel-based tools vs. manual spreadsheets 

There is an important distinction between manual spreadsheet models and structured Excel-based tools. Excel-based tooling allows finance teams to retain the transparency and flexibility of spreadsheets while applying more robust and controlled calculation frameworks.

  • Use standardised data inputs 
  • Embed consistent calculation logic 
  • Produce repeatable, auditable outputs 
  • Reduce reliance on ad-hoc formulas and manual intervention
