Why Excel isn't enough for CSRD

Why Excel is not sufficient for CSRD reporting

Many companies use Excel as a first tool to approach CSRD reporting . Spreadsheets are familiar, flexible, and quick to deploy. For an initial overview, this can be useful.
In practice, however, it becomes clear: The requirements of the CSRD go far beyond what Excel can deliver in the long term.

This article provides an assessment of when Excel can be used effectively and where more structured solutions become necessary for companies.

Excel vs. Software: Which solution is right for CSRD?

With the CSRD, sustainability reporting becomes:

• more comprehensive
• more data-intensive
• audit-relevant
• annually recurring

Under the CSRD, companies must not only report results but also transparently demonstrate how these were achieved. This includes clearly defined processes, traceable evaluation logic, and documented decisions over time.

Especially at the beginning, it can be useful to work with Excel, for example, to structure initial topics, collect data, or develop a basic understanding of the requirements. However, as the depth and complexity of CSRD requirements increase, it quickly becomes clear that Excel is only suitable to a limited extent.

As soon as multiple departments are involved, data needs to be updated regularly, or auditable documentation is required, spreadsheet-based approaches reach their limits. CSRD thus evolves from a one-time task into a continuous management process, which in the long term requires structured processes and suitable systems, not just individual Excel files.

Limitations of Excel in CSRD Implementation

1. Limited Transparency with Growing Data Volumes

With an increasing number of:

• Topics
• KPIs
• involved departments

multiple spreadsheets and versions quickly emerge. This makes it difficult for companies to maintain a consistent overall picture and reliably track changes.

2. Traceability and Audit Requirements

CSRD reports are subject to external audit. Auditors expect:

• a clear derivation of results
• documented assessment standards
• traceable changes over time

Excel offers only limited capabilities for this. In particular, a comprehensive audit trail can only be achieved with significant manual effort.

3. Significant Coordination Effort

CSRD affects numerous departments. In Excel, data must be:

• manually consolidated
• coordinated
• monitored

This increases the coordination effort and ties up internal resources, especially when processes are repeated annually.

4. Structured Representation of Double Materiality

Double materiality requires a clear separation of impact and financial perspectives, defined criteria, and transparent assessment decisions.
While this is generally possible in Excel, it is often:

• difficult to understand
• poorly standardized
• difficult to reproduce

This can become a challenge, especially during subsequent audits or internal queries.

5. Scalability across multiple reporting years

CSRD is designed for the long term. Data, assessments, and processes must be:

• updated annually
• comparable
• further developed

Excel is only partially suitable for this, as it offers limited structured management of historical data, changes, and responsibilities.

When Software Becomes Useful for CSRD

Many companies reach a point during their CSRD preparation where the effort significantly increases. The volume of relevant data grows, requirements become more complex, and the question of Auditability is increasingly becoming a focus. It quickly becomes clear that manual, spreadsheet-based approaches are only manageable with significant effort.

Particularly for companies subject to CSRD software becomes almost indispensable. The directive not only requires comprehensive content, but also traceable documentation of processes, assessments, and decisions across multiple reporting years. Specialized software solutions help by centralizing data, standardizing processes, and clearly defining responsibilities. Changes to content or assessments are automatically documented, significantly simplifying subsequent audits.

However, even for companies not directly subject to CSRD using software can be beneficial. Many of these companies are indirectly impacted – for instance, by customers, investors, or banks increasingly requesting structured sustainability information. Adopting a systematic approach early on creates transparency, reduces future transition efforts, and better prepares companies for upcoming regulatory requirements.

Another advantage lies in cross-departmental collaboration. CSRD-relevant data doesn't originate in a single place but across various departments such as procurement, HR, finance, and sustainability. Software facilitates collaboration by defining clear roles, simplifying coordination, and making information available in a central location.

Overall, using software helps transform CSRD from a complex mandatory task into a manageable, repeatable process . This makes sustainability reporting not only manageable but also efficient and future-proof in the long term.

Implement CSRD systematically with cubemos

cubemos helps companies systematically address CSRD requirements – from double materiality to documenting results.

With cubemos, companies can:

• Systematically capture sustainability topics
• Transparently assess impact and financial materiality
• Document assessment methodologies transparently
• Involve various departments
• Prepare for audits

This creates a clear, repeatable process, which goes beyond individual Excel files.

Conclusion: Excel as a Starting Point – Software as a Long-Term Solution

Excel can be a useful starting point.
For a lasting, auditable, and scalable CSRD implementation spreadsheets, however, quickly reach their limits.

Companies that view CSRD as a continuous process benefit from focusing early on structured systems and suitable software to rely on.
