Notes de l'éditeur
- Not, many you….See, Power Query is one of the most powerful tools you can use in Excel, unfortunately most people don’t take advantage of this tool, just because they don’t know that it exists or what it does. You can find Power Query in the Data Ribbon under the Get and Transform section. The layout on Excel 2019 and Office 365 changed a tiny bit compared to Excel 2016, however the location is still the same under the data ribbon
- Analytics: Report only needs to be created once. Data is always up to date but analysis (report) might not be in the nicest format Excel: everyone knows how to use it! Very robust easy but at the same time hard! If you need to transform data you need to repeat steps everytime you bring more data Power Query: The best of both worlds. Like an Analysis in analytics, you create your report once and after that you only need to refresh the data. At the same time you Power Query equally or even more robust than Excel. It is much easier to use, however is not as flexible. There is no best tool, there are only trade off. Do you prioritize
