Excel Champion Diarmuid Early Shares Essential Tips for Office Workers

Diarmuid Early has emerged as the champion of the 2025 Microsoft Excel World Championship, showcasing not only his skills but also offering valuable insights for office workers looking to enhance their productivity. Early, who has dedicated over 20 years to mastering Excel, emphasizes that there are always better methods to approach common tasks.

Having honed his skills at the Boston Consulting Group and Deutsche Bank, Early founded his own Excel advisory firm six years ago. In a recent discussion with Business Insider, he shared fundamental tips that can transform the way professionals interact with spreadsheets.

Rethink Your Approach to Repetitive Tasks

Early’s primary piece of advice is simple yet profound: always believe there is a more efficient way to accomplish tasks. He notes that many office workers often find themselves engaged in tedious copying and pasting, which can lead to frustration. “If you notice yourself doing something manually and repetitively, there is a high chance Excel has a better solution,” he stated.

He encourages workers to leverage online resources. “If you Google a concise description of your issue, there is a significant chance that someone has encountered the same problem and has shared a solution online,” Early explained. His experience suggests that approximately 80% of Excel struggles can be resolved by simple internet searches.

Learning functions like SUMIFS may initially take longer than manual methods, but Early insists that the time invested will pay off significantly in the long run. “It may take longer the first time, but as you master these functions, the speed at which you can execute them increases exponentially,” he added.

The Importance of Insight Over Speed

With newfound efficiency comes the opportunity to reflect on the results. Early highlights that speed should not come at the expense of understanding. “Once you quickly arrive at an answer, take a moment to assess whether it makes sense,” he advised. This critical thinking is often overlooked by junior employees, who may feel pressured to deliver results quickly.

By taking the time to analyze results, employees can build credibility and reduce the risk of errors. Early pointed out that this practice not only enhances personal skills but also makes it easier to identify and rectify mistakes before they are noticed by others.

Concerns about the role of artificial intelligence in Excel’s future are also on Early’s mind. He acknowledges that while AI can assist users in navigating Excel, it may not provide the same depth of guidance that experienced users can offer. “If AI can outperform human users, it raises questions about the future of our roles,” he remarked.

Ultimately, Early’s journey to victory in the Excel World Championship underscores the value of continuous learning and adaptation in the workplace. With a treasure trove of tips and tricks, he is determined to help office workers harness the full potential of Excel, transforming mundane tasks into streamlined processes.

As he reflects on his achievement, Early remains committed to sharing his knowledge, aiming to empower others in their Excel journeys. “Every time I teach someone a new trick, I can see the joy and relief on their faces,” he concluded. “That is what makes this journey worthwhile.”
