If you need to analyse data then this is the course for you.

Many people use Excel to analyse data, and this works well for simple data sets that can be represented by a single table with less than a million rows. Even then Excel doesn't make it easy to produce good looking and easily shareable reports and dashboards.

If the data source is a database or simply involves pulling data from several different files or systems, then Power BI will make your life easier. Building reports and dashboards from this data and subsequently sharing the results is exactly what it's designed to do.
