An Excel Spreadsheet Is Not a Database: Why Quality Data Matters for DoC and PPWR Compliance

When a company manages hundreds of products and multiple packaging configurations, preparing and maintaining compliance documentation becomes a serious challenge. The issue is not just the volume of data, but how easily that data can be kept accurate, consistent, and up to date.

In many companies, information about products, packaging materials, and suppliers is scattered across Excel spreadsheets, individual documents, and separate internal records. This approach may work when the product portfolio is small and changes are infrequent.

But what happens when a company manages hundreds of SKUs, multiple packaging types, and different combinations of materials? What if a supplier changes, a material specification is updated, or the packaging composition is modified?

Even a seemingly minor change can require reviewing multiple records and documents. When data is not properly structured and connected, the risk of errors, outdated information, and duplicated work increases.

A DoC Is Not a One-Time Task

A Declaration of Conformity (DoC) is part of the documentation used to demonstrate that a product or packaging meets applicable requirements. In the context of the Packaging and Packaging Waste Regulation (PPWR), companies need to pay particular attention to the data and documentation supporting the assessment and demonstration of conformity.

Creating a document once is not enough if the underlying data continues to change.

A change in supplier, material, or packaging configuration may require an assessment of its impact on existing data and documentation. Without a clear record of which products and packaging components are linked to specific materials and suppliers, maintaining accurate documentation quickly becomes complicated.

From Spreadsheets to Structured Data Management

The solution is not necessarily more spreadsheets or additional manual checks. What companies need is a structured system in which information about products, packaging components, materials, and suppliers is connected, organized, and easy to maintain.

Such an approach enables:

  • Centralized data: Relevant information is available in one structured environment.

  • Better change traceability: It is easier to identify which products and documents are affected by a change in material or supplier.

  • Less manual work: Automation reduces repetitive data entry and duplication.

  • Simplified documentation management: Changes can be assessed and processed through a defined workflow.

  • A more reliable basis for compliance: Documentation can be generated using structured, complete, and verified data.

It is important to distinguish between automating document generation and automating the entire data management process. An automatically generated document is only as reliable as the quality, completeness, and accuracy of the data behind it.

The Goal Is Not Just to Create a DoC. It Is to Keep Your Data Under Control

When data is properly structured, documentation becomes part of a well-defined process rather than a separate project that must be repeated every time something changes.

This is particularly important for companies managing large product portfolios and complex packaging configurations. Instead of relying on manually maintained files, they can build a system that connects relevant information and simplifies the preparation and maintenance of documentation.

At Kaligraf, we help companies explore how to organize their data and connect it with their documentation processes. Because effective data management is not just about efficiency. It is the foundation for reliable, consistent, and sustainable documentation management.
