Why Excel isn’t enough for DORA reporting: key lessons from the ESA dry run

Ariadnah Solutions DORA 23 Jul 2025 1 min read

Discover the implications of the Digital Operational Resilience Act (DORA) for financial entities in our comprehensive document. With mandatory reporting for ICT third-party service providers set for

The Digital Operational Resilience Act (DORA) requires financial entities to report detailed contractual information about ICT third-party service providers starting January 2025.

In a recent voluntary dry run exercise conducted by the European Supervisory Authorities (ESAs), many institutions learned a hard truth: Excel is no longer enough to meet these reporting demands.

01

Key findings from the ESA dry run

1. High error rates

Out of 1,039 participating financial entities:

  • Only 6.5% passed all data quality checks
  • A staggering 93.5% had at least one error

This clearly highlights the risks of manual processes and reliance on spreadsheets.

2. Missing mandatory fields

More than 86% of all data errors were due to missing mandatory fields, including:

  • Identification codes for ICT third-party providers
  • Details on ICT services and contractual arrangements

While the dry run allowed partial submissions, final reporting will require complete and validated data.

3. Complexity will increase

The dry run included optional fields. From 2025 onward, all fields will be mandatory, significantly increasing reporting complexity.

02

Why Excel falls short

Excel may seem familiar and flexible, but it introduces several compliance risks:

  • Human error: Managing complex data manually is prone to mistakes
  • Validation gaps: Excel doesn’t enforce advanced data validation like a real data point model (DPM)
  • Scalability issues: Excel struggles with large, structured datasets and slows down reporting workflows

03

The solution: robust tooling

To meet DORA’s demanding requirements, financial entities should implement automated, purpose-built tools that:

  • Ensure data accuracy and completeness
  • Streamline reporting workflows
  • Validate submissions against regulatory technical standards

Institutions adopting the right tools won’t just comply — they’ll improve their overall ICT risk management capabilities.

04

Final thoughts

The ESA dry run sends a clear message: Excel isn’t sustainable for DORA compliance.
