00:04After connecting to sources, users can examine and filter data using Tableau Prep's visual interface.
00:12It's important to conduct these steps before making any major changes to your data in the flow.
00:18There are a few different ways to examine your data using Tableau Prep.
00:22First, you can profile your data by looking at field value distributions.
00:26Additionally, you can review data types, data size, and find specific fields or values of interest.
00:34Finally, you can sort and highlight your values in your fields to find gaps or deficiencies.
00:40Examining is a great way to find outliers and trends in your data prior to doing cleansing.
00:45In addition to examining your data, you should also filter your data up front.
00:50Filtering your data up front will reduce the data being pulled into your flow using various tools from Tableau Prep.
00:57You'll also be able to organize your flow's tools and settings for optimal performance and clear documentation throughout the process.
