Final answer:
Two ways to perform a bulk update of data for 225 contacts involve using Excel Online to save changes directly to Microsoft Dynamics 365, or exporting the data as a static worksheet, making updates, and re-importing the data back into Dynamics 365.
Step-by-step explanation:
To perform a bulk update of data for 225 contacts using Microsoft Excel and Excel Online, with the goal of saving changes to Microsoft Dynamics 365, there are a couple of methods you could use.
Option A: Excel Online
The first method is to use Excel Online. You would open the data in Excel Online, make the necessary updates, and then, assuming there is an integration, save the changes directly into Microsoft Dynamics 365. This method is convenient as it relies on cloud-based functionalities and does not require data to be re-imported back into Dynamics 365.
Option D: Static Worksheet
The second method involves exporting the data as a static worksheet, making updates in Microsoft Excel on your desktop, and then importing the data back into Microsoft Dynamics 365. Download the table in Excel by selecting the XLS option and then choosing where to save the file. After making your updates, you would import the updated file back into Dynamics 365 to complete the bulk update process.
