Another hidden gem in Tableau is the 'Data Interpreter' feature. It automatically detects and fixes common data quality issues like headers, misaligned data, inconsistent formatting, and even blank rows, making the data preparation process much easier.

Did you know that Tableau has built-in mapping capabilities? By simply dragging and dropping geographic data onto a visualization, you can create interactive maps that provide insights based on location. This feature is often overlooked, but it can be extremely valuable for spatial analysis.
