With pages that display a list of records in rows and columns, like a list of customers, sale orders, or invoices, you can export the list to Microsoft Excel, and view it there. Depending on the page, you have two options for viewing in Excel. Both options are available from the Share icon 
at the top of a page. You can either select the Open in Excel action or the Edit in Excel action on the page. This article explains the differences between the two actions.
Open in Excel
With the Open in Excel action, you can make changes to the records in Excel, but you can't publish the changes back to Business Central. You can only save the changes to Excel file, without affecting data in Business Central.
-
With this action, Excel respects any filters on the page that limit the records shown. The Excel workbook will contain the same rows and columns that appear on the page in Business Central.
-
This action works on both on Windows and macOS.
-
Starting with update 18.3, you can also view lists that are shown in page parts, like the lines in a sales order.
Note
For Business Central on-premises, the Open in Excel action is available by default. However, if you set up Business Central on-premises for editing data in Excel, then the Open in Excel action is replaced by the Edit in Excel action.
Tip
What about reports? Well, you can export the report results to an Excel file for viewing the full dataset, including all columns. The Excel file can help you validate that the report returns the expected data. To export a report, run the report and select the Send to > Microsoft Excel Document (data only) on the request page. For more information, see Working with Reports - Send to Excel.
Edit in Excel
The Edit in Excel action is available on most lists, but not all. With the Edit in Excel action, you make changes to records in Excel and then publish the changes back to Business Central. When Excel opens, you'll see the Excel Add-in pane on the right.
-
With this action, Excel respects most filters on the page that limit the records shown, so the Excel workbook will contain almost the same records and columns.
-
To get the latest data from Business Central, choose Refresh in the the Excel Add-in pane.
-
You can switch the company that you're working with. To switch company, select the Options icon
in the Excel Add-in pane, then select the company from the Company field.Important
When changing the company, make sure that the Environment field is not empty. If it is, then set it to one of the available options; otherwise, the add-in will not work correctly.
If you make changes to the add-in, you must reload it to update the connection. To reload, use the 
menu in the top-right corner of the add-in. If you can't load the add-in, talk to your administrator. If you're the administrator, see Get the Business Central Add-in for Excel.
