Microsoft Flow using both SharePoint and Excel

Good afternoon,


I am trying to create a flow that takes data from Microsoft Excel, determines whether this data needs to be created as a new SharePoint item, or if it already exists in SharePoint, and just needs to be updated, before finally sending a confirmation email when finished.


It is not the most complicated flow in the world, but for some reason, each time I try to test the workflow, I receive a "input array is empty" message and the flow stops.  Any thoughts as to what I am forgetting to include or where I am going wrong?


I have included a screenshot of what I have thus far, plus another screenshot showing what happens whenever I try to run the flow and receive the "input array is empty" message.  To determine whether or not a new SharePoint item is needed, I took a common field from Excel and SharePoint and simply asked the system to look for a match.  This flow seemed so easy at first, but I am completely stumped.  Any help would be greatly appreciated!!Picture2.pngPicture1.png

Re: Microsoft Flow using both SharePoint and Excel

Hi @nelsonbj,


Could you provide the details of your SharePoint list, is it initially an empty list?

The reason I want to see this issue is that there is no item in the SharePoint list.

If you want to use the Value of Get items in Apply_to_each, please make sure there is at least one item in the SharePoint List.

You could manually add an item to the list in advance, and then delete it after adding a new item.

Please take a try and let me know if issue still exists.


Best Regards,

Re: Microsoft Flow using both SharePoint and Excel

It was originally an empty list... and as soon as I added a test item to the SharePoint List, Flow realizes that the condition is not empty and completes the rest of the actions.  However, now whenever I run this flow, I see a lot of duplicate items...  Does this have something to do with the "Apply to Each" condition?  And how could I get rid of the Apply to Each to ensure that this flow is only runs once?


Thanks for your help and quick reply!
