Copilot Tip: Make Sense of Messy Excel Data Without Writing Formulas

31 March 2026

Excel is where most business data lives and where a lot of time disappears. Cleaning data, building formulas, and answering “quick” questions can easily turn into a slow, frustrating process.

Copilot changes that, especially when you treat it as a data interpreter rather than just a calculator.

The tip

Ask Copilot questions about your data, not about formulas.

Instead of trying to remember the right formula or building pivot tables from scratch, start by asking what your data actually means.

Try prompts like:

• “Summarise the key trends in this data.”
• “Are there any anomalies or outliers I should be aware of?”
• “Group this data by month and show totals.”
• “What insights would be useful for management?”

Copilot will analyse your dataset and either explain the insights in plain English or generate the tables, columns, or formulas for you.

Where this works best

Data clean-up
Dealing with inconsistent entries, missing values, or formatting issues? Copilot can suggest how to standardise your data without digging through menus or searching for the right formula.

Understanding formulas you didn’t write
Inherited spreadsheets are often full of complex, undocumented formulas. Copilot can break these down into plain language, making them much easier to review and update safely.

Quick analysis without pivots
For ad hoc questions like totals, averages, trends, or comparisons, Copilot can give you answers instantly without setting up a full pivot table.

Turning data into insight
Questions like “What changed?”, “What stands out?” or “What should I focus on?” are where Copilot really shines. It helps you get to the point faster.

A practical example

Instead of building everything manually, try:

“Based on this spreadsheet, summarise the key trends and highlight anything unusual.”

Copilot might:

• Create a summary table
• Highlight spikes or gaps
• Suggest charts
• Flag inconsistent entries

From there, you refine rather than start from scratch.

Why this matters

Most people don’t struggle with Excel itself. They struggle with the time it takes to turn raw data into something useful.

Copilot helps by:

• Reducing manual analysis time
• Lowering the barrier to advanced features
• Making spreadsheets more accessible to non-experts

The result is faster insights, fewer errors, and less reliance on a single “Excel expert” in the team.

One thing to keep in mind

Copilot works best when your data is reasonably well-structured:

• Clear headers
• Consistent formats
• No completely blank rows or columns

It doesn’t need to be perfect, but cleaner data leads to better results. Next time you open a spreadsheet, don’t start with formulas. Start with a question, and let Copilot do the heavy lifting.
