Use this interactive demo to learn how to change data types and format columns in Power BI.

Quick summary

This tutorial shows how to format data in Power BI by navigating to the Table view and using Column tools to change data types for any column. Following these steps ensures your Power BI reports display accurate, consistently typed data across all visuals.


Steps

  1. Open your report and select your visual to begin formatting.
  2. Go to the Table view of your data.

📌 Why this matters

Correctly formatting data in Power BI is essential for accurate reporting, reliable calculations, and consistent visual outputs. Assigning the right data type to each column — such as text, number, or date — prevents errors in aggregations and filters across dashboards. This process is especially critical for data analysts and business intelligence teams who need their reports to reflect trustworthy, well-structured data. Mastering Power BI data formatting reduces manual cleanup time and improves the overall quality of insights delivered to stakeholders.
