What is Tableau?
Tableau is a software created for data visualization. It lets you import or live connect to excel, csv, json, and many other various file types. With a few clicks it begins creating common visualizations that let you immediately begin analyzing and presenting your data.
How is Tableau different from excel?
This is tough to answer since excel can do so much. The common answer is that Tableau is a time saver. Building a comprehensive, dynamic, and visually pleasing dashboard in excel can take hours to put together, especially if it is the first time you are working with the data and figuring out what and how you want to visualize, and that is after you have already cleaned up your data sheet. With Tableau, you connect to your data sheet, select a few fields, and it will immediately show you the best visualizations for the fields you have selected. There are other differences, like excel being a spreadsheet tool and Tableau being a data visualization tool, but it is difficult to get behind that explanation since you can visualize so much in excel.
