The best data sources are ones that don't require any cleaning. All of the data matches up, there are no stray values, and you can join the fields easily. Reality is rarely so kind. In this movie, the data cleaning tool is introduced, the tool that helps you import your data and manage any issues that come due to inconsistencies in the source file.
- [Narrator] Most of the time,…the data that you bring into Tableau will be pretty clean.…You will have Excel workbooks…that contain single tables with no stray values…that can throw off the data interpretation.…However, there might be times when you find…that your data isn't formatted as cleanly as it should be,…and Tableau has a hard time reading it.…In this movie, I will show you how to use…the Data Interpreter to clean up data…that you're reading in.…I have started Tableau, and I have a blank workbook…with the start screen displayed.…
From here I want to bring in an Excel workbook,…so I will go to the Connect tab, and click Excel.…And then, in the Chapter02 folder…of the Exercise Files folder,…I will double-click YearlyData.…Doing so takes me to the connection screen,…but you can see already that there might be a problem.…In the left-hand panel here,…you can see Tableau has displayed a message saying…that Data Interpreter might be able…to clean my Excel workbook.…
I don't know what the problem is,…so what I will do is double-click the Products sheet,…
