Reporting Marketing Mix: From Dirty Excel to Decision-Ready Insights

Most marketing data problems are not about missing data. They are about broken structure, and raw exports sent to people who need a decision.

Cleaning scattered Excel mini-tables into one reportable dataset made reporting faster and removed useless metrics. The next step is turning that clean table into a decision note: what changed, why, what to do, and how sure you are.

Torn spreadsheet pages and glass tiles scattered around one glowing four-part marketing chart with a check mark at its centre, beside the n-g.be ice cubes and blue flame.

In-Short

Structure Before Dashboards

The data was always there. It lived in mini-tables with inconsistent headers, broken formats and duplicates. Consolidating it into one consistent dataset is what made it reportable, and simple charts showed insights right away.

Leadership Needs a Decision Shape

A CEO does not need fourteen tabs. They need what changed, why it matters, what should happen next, and how sure you are. If the report keeps the shape of the export, people ask for another meeting instead of deciding.

One Metric, One Owner

"Revenue" can mean booked, paid or net depending on the export. Once definitions drift, the meeting becomes a debate about words. Every important metric needs one definition and one owner.

Think Like a Kitchen, Not a Workbook

The spreadsheet is the pantry. The cleanup layer is the prep. The CEO wants the plate. AI is the pass between the kitchen and the table: it helps turn preparation into something people understand fast, but it does not decide whether the dish is good.

Part 1: The case

Long Read

Messy Excel sheets rarely fail because of volume. They fail because of structure, and because raw exports get sent to people who need a decision. Clean the data into one reportable table, then turn that table into a decision note leadership can act on.
