Every finance team has that workbook.

The one that takes a little too long to open. The one that asks whether you want to update links nobody quite recognizes. The one everyone relies on, but nobody wants to touch a week before close.

It still works. For now.

And there’s that one person on the team that knows exactly what to do when it needs fixing.

That’s where spreadsheet risk can hide, in the everyday workarounds that have become so familiar, people stop questioning them.

How did we get here?

Spreadsheets earn their place in finance. They help teams answer questions, handle exceptions, and get work done when a system doesn’t quite deliver what’s needed.

But a workbook built to solve one problem can take on a much bigger job.

Next month, someone copies it forward. Another department needs a version. A new reporting requirement adds a few tabs. Someone adds a formula, a connection, or a macro.

A few years later, that workbook is helping produce numbers for leadership. It has become part of the reporting infrastructure, even though it’s still managed much as it was on day one.

The numbers can be right—and the process can still be fragile

We’ve seen  reporting workbooks with more than 900 external workbook links, with references stretching back decades. The files opened slowly, prompted users about obscure links, and had become difficult for anyone to explain fully.

In another, an apparently automatic data refresh depended on a macro in one employee’s workbook. Everything worked because that particular file opened at the right time. When the person who built it left, the team had to figure out what was keeping the process running.

A common problem we've seen is that people are actually afraid to make changes to their spreadsheets because they don't know what might break. Even something as simple as adding or deleting rows or columns can introduce problems.

These are the kinds of situations worth examining before the next close puts them under pressure.

Three places to look

The guide breaks spreadsheet risk into three areas:

Structure: Can you explain how the workbook produces its results? Or have years of formulas, links, and additions made it difficult to follow?

Process: Can another person run it reliably? Or does success depend on someone remembering which file to open, what to paste, and when to refresh?

Control: Does everyone know which version to use, who can change it, and what changed since the last reporting cycle?

A useful question is: If the person who knows this workbook best were unavailable tomorrow, how confident would you feel?

We’ve had customers tell us that job mobility within the organization can be limited because one person is needed to maintain and run certain reports. It limits when people can take vacations and impacts necessary leaves, causing alarm and extra work for those who need to step in.

Keep the flexibility. Give it the support it needs.

Finance teams need spreadsheets. They also need confidence that the work behind their reports is repeatable, explainable, and controlled.

That means giving important workbooks clear ownership, managed templates, appropriate access, and reliable data refresh. Those are the capabilities Dodeca brings to spreadsheet-driven reporting. Governance without removing Excel.
