Unlock the power of your legacy data. This guide explains how to connect outdated systems like Microsoft Access, FoxPro, and CSVs to Power BI. Learn to bridge the gap by automating data cleaning and transformation, enabling powerful, real-time dashboards without a costly migration. Your legacy data deserves modern insights.

If your job involves getting insights out of aging databases like Microsoft Access, FoxPro, or even exported CSVs from a VB6 app, you’ve probably been told: “Just put it in Power BI.”

Sounds great — until you try it.

Power BI is one of the most powerful business intelligence tools on the market, but it doesn’t always play nicely with the systems many companies still rely on. If you’ve struggled to get legacy data into a usable dashboard, you’re not alone.

• Predictable schemas (column headers, data types)
• Up-to-date or refreshed datasets
• Structured data pipelines (e.g., Azure Blob, Dataflows, SQL Server)
