Using Excel as a data source for Power BI is risky business. Excel’s volatility—from typos and inconsistent entries to frequent formatting changes—makes it a poor choice for producing reliable data insights. Even minor alterations, like a column header change or sheet rename, can cause errors that take analysts hours to trace and fix. Power BI works best with structured, stable data. When Excel disrupts that stability, the risk of poor data quality and frequent report errors skyrockets. This not only impacts the accuracy of insights but also chips away at your team’s trust in Power BI. Lose trust in one report, and you may lose it in all, making it harder to create a data-driven culture. For consistent, reliable reporting, consider using a dedicated database or data warehouse, and let Power BI do what it does best—deliver clear, actionable insights. All the Best, Tucker |
