What Is Tableau Software?

1. Data Cleaning with Tableau Prep
Data is rarely perfect when an analyst first receives it. When asking what is tableau used for, you must include data preparation. What is Tableau Prep specifically? It is a tool that allows an analyst to pivot, join, and clean “messy” data visually. This saves hours of manual work that would otherwise be done in Excel.

Analysts build dashboards that update automatically. A business leader can click on a specific region on a map, and the entire dashboard will filter to show only the data for that area. This interactivity makes the analyst’s work much more engaging for the end-user.
3. Identifying Trends and Patterns
An analyst uses the tool to perform “trend analysis.” By looking at data over time, they can predict what might happen in the future. This helps a company decide where to invest money or how to improve customer service.
4. Sharing Insights Securely
Once the analysis is complete, the analyst publishes the work to Tableau Server. This ensures that only the right people see the data, maintaining privacy while providing the necessary information to decision-makers.
