Tableau Prep
Tableau Prep is a data preparation tool designed to clean, shape, and combine data from various sources for analysis in Tableau. It provides a visual, drag-and-drop interface that allows users to transform raw data into analysis-ready datasets without writing code. The tool is part of the Tableau platform and integrates seamlessly with Tableau Desktop and Tableau Server for creating dashboards and reports.
Developers should learn Tableau Prep when working in data analytics or business intelligence roles that require efficient data wrangling before visualization. It is particularly useful for handling messy data, automating repetitive cleaning tasks, and ensuring data consistency across multiple sources. Use cases include preparing sales data for quarterly reports, merging customer datasets from different systems, and standardizing formats for time-series analysis.
