Excel and Power BI for Finance Professionals — Skills Guide 2026

Excel and Power BI are two of the most important tools in a finance professional's kit — and knowing how they complement each other is increasingly valuable. Excel remains the workhorse for modelling and analysis; Power BI brings powerful, interactive dashboards and reporting at scale. This guide explains what each does, how they work together, when to use which, and why both matter for finance — in clear, plain language. Strong data skills like these underpin modern finance work and complement professional study like CIMA and ACCA.

What each tool is for

Excel is the familiar, hugely flexible spreadsheet that finance professionals use for modelling, analysis, calculations and ad-hoc work. Its strength is flexibility — you can build almost anything, quickly. Power BI is Microsoft's dedicated business-intelligence tool, built specifically for connecting to data, transforming it, and producing interactive dashboards and reports that can be shared and refreshed automatically. Where Excel is a general-purpose tool, Power BI is purpose-built for reporting and visualisation at scale.

How they work together

Importantly, Excel and Power BI aren't rivals — they share technology and work well together. Both use the same underlying engines for data preparation (Power Query) and modelling (the Power Pivot / data-model engine), so skills transfer directly between them. A common pattern is to use Excel for modelling and detailed analysis and Power BI for polished, interactive dashboards that present results to the wider business. Power BI can also connect to Excel files and other sources, pulling data together into a single reporting layer.

When to use which

Choosing between them comes down to the task:

• Use Excel for building financial models, detailed analysis, calculations, ad-hoc work, and smaller data sets you want to manipulate directly.
• Use Power BI for interactive dashboards, reporting at scale, large data volumes, automated scheduled refresh, sharing reports across an organisation, and creating a "single source of truth".

In practice, many finance teams use both — Excel for the hands-on analytical work, Power BI for the reporting and dashboards that go to management.

An example: monthly management reporting

Consider a finance team producing a monthly management pack. In a traditional Excel-only approach, someone spends days each month pulling data from various systems, cleaning it, rebuilding charts and reformatting the pack — repetitive work, repeated every period. A combined approach changes this. Power Query automates the data gathering and cleaning; a Power BI dashboard presents the results interactively, refreshing with a click (or on a schedule) as new data arrives, and lets managers drill into the numbers themselves. Excel still does the detailed modelling and any bespoke analysis behind the scenes. The result is a reporting process that takes a fraction of the time, looks more professional, and gives the business self-service access to its own numbers — a transformation many finance teams are now making.

Why both matter for finance

Together, Excel and Power BI cover the full span of finance data work. They let teams consolidate data from multiple sources, build automated, refreshable reporting rather than rebuilding reports each month, create interactive dashboards that let users explore the numbers, and move towards self-service analytics across the business. For finance functions under pressure to deliver faster, richer insight, these capabilities are increasingly essential — and professionals who know both tools are well placed to deliver them.

Building the skills

Because Excel and Power BI share the Power Query and data-model engines, learning one accelerates the other. A sensible path is to strengthen your Excel data skills first — particularly Power Query and PivotTables — then move into Power BI, where much of that knowledge carries straight over. Start by rebuilding a report you already produce in Excel as a Power BI dashboard, to see the difference first-hand. These are among the most in-demand skills in finance today, and they reward steady, practical learning on real tasks.

Frequently asked questions

What's the difference between Excel and Power BI?

Excel is a flexible general-purpose spreadsheet for modelling and analysis; Power BI is a dedicated business-intelligence tool for connecting to data and producing interactive, shareable, refreshable dashboards and reports.

Do Excel and Power BI work together?

Yes — they share the same data-preparation (Power Query) and modelling engines, skills transfer between them, and Power BI can connect to Excel data. They complement rather than replace each other.

When should I use Power BI instead of Excel?

For interactive dashboards, large data volumes, automated refresh, sharing reports across an organisation, and creating a single source of truth — while Excel suits modelling, analysis and ad-hoc work.

Which should I learn first?

Strengthen your Excel data skills first (especially Power Query and PivotTables), then move into Power BI, where much of that knowledge carries straight over because they share the same engines.
