In this topic, we'll cover data management in the Common Data Service. We have touched on importing and exporting data in other topics, but we'll spend more time now on working with data in Excel.
In this example, we'll import data from Excel into the Product review entity that we created in the last topic. You can also import data from CSV files, which is a common format to move data around. Here's a reminder of what the entity looks like; the highlighted area is what we'll focus on in this topic.
In an entity, click Import data, then navigate to the file you want to import from. Click Show mapping and make sure the columns in the Excel file are associated with the right fields in the entity. When you're happy with the mappings, click Save changes. Back on the main import screen, click Import.
Export data if you need access to it outside the Common Data Service. In an entity, click Export Data, and then wait for the zip file to be generated. Open the zip file and you see the exported data.
In addition to downloading data, you can download a template. A template is an Excel file with a structure that matches the fields of an entity, but without the data. After you download the template, you populate it manually or programmatically, and import it back into the service. In an entity, click Export Template, then specify the fields you want (in this case I selected a single field). Click Export to Excel, and then wait for the Excel file to be generated. Open the Excel file and you see the exported template with the fields you selected.
The last thing we'll look at is the Open in Excel option. If you have the PowerApps add-in installed, you can use this option to explore and edit your data in Excel. In an entity, click Open in Excel, then open the file. Enable editing, then the add-in establishes a live connection to the entity in the service and populates the workbook. You edit directly in the workbook, and can add and delete rows. Click Publish to save changes. You can also refresh data to make sure you have an up-to-date copy; and filter data, which is especially handy if an entity has a lot of data in it.
That wraps up the topic on managing data in the Common Data Service—importing, exporting, and working with data in Excel. In the next topic, we'll talk about managing data security.
