Which option is used in Power Query Editor to check empty or error values for all columns?

The option used in Power Query Editor to check for empty or error values across all columns is referred to as "Column Quality." This feature provides insights into the health and integrity of the data within each column. It allows users to quickly assess the quality of the data, highlighting any issues such as blank values or errors.

When analyzing data, understanding the quality of each column is vital for ensuring that subsequent transformations or analyses are based on accurate and reliable information. "Column Quality" gives a visual representation of the data's condition, enabling users to take corrective actions if necessary before proceeding with further data manipulation or reporting.

While other options like "Data quality analysis" and "Column profile" do relate to data assessment in Power Query, they do not specifically focus on the ability to view empty or error values in the way that "Column Quality" does. "Dataset overview" provides a more generalized view of the dataset but does not offer the specific depth of analysis that the "Column Quality" feature presents.
