1. Don’t wait for your source data from flat files to be perfect?
Data Interpreter can give you a head start when cleaning your data. It can detect things like titles, notes, footers, empty cells, and so on and bypass them to identify the actual fields and values in your data set.
It can even detect additional tables and sub-tables so that you can work with a subset of your data independently of the other data.Click on the Checkbox to prep your data

If your data needs more cleaning or data stewardship, then go for “Tableau Prep Builder” – Combine, shape, and clean your data for analysis
