The Data Revolution Is Accelerating — And It Starts with Excel
Every so often, someone declares Excel dead. Every time, they’re wrong. In 2026, Microsoft Excel remains the backbone of business analysis — but the professionals thriving in the data economy aren’t using it in isolation. They’re combining Excel with Power BI, Python, and AI-powered analytics to turn raw data into boardroom-ready insights.
The numbers are staggering. The global data analytics market is expected to cross $650 billion by 2029, and over 80% of analyst job postings still list Excel and Power BI as core requirements. But the roles commanding the highest salaries belong to professionals who treat these tools as a unified ecosystem.
What 2026 Employers Are Actually Looking For
According to the latest industry surveys, the modern data professional needs to be comfortable with:
- Excel — advanced functions, pivot tables, Power Query, and dynamic array formulas
- Power BI — interactive dashboards, DAX measures, and data modelling
- Python — automation, data wrangling, and analysis via Pandas and NumPy
- SQL — querying databases and understanding data engineering basics
- AI literacy — using Copilot in Excel and AI-assisted analytics tools
The teams getting the most out of financial modelling in 2026 are those treating Excel, Python, and Power BI as one integrated system — not three separate applications.
Power BI: From Nice-to-Have to Non-Negotiable
Power BI has firmly established itself as the dominant business intelligence tool in Irish organisations. With Copilot now integrated directly into Power BI, professionals can generate DAX formulas, create visuals, and build reports simply by describing what they want in plain English. But understanding the underlying principles — data models, relationships, measures — still determines who gets the best results.
