Power Platform Community Forum Thread Details

Hello,

I have been working on building flow to automate data from excel to MS list. The flow seem to run successfully. When I open List to see the result, it show blank column. Basically, when I read the raw code in power automate, it run to 'update item' where it update blank value into the List, when I suppose to not update or just overwrite the existing row. Does anyone has experience with this issues? What is the problem causing it to error like this?

Building flows

The logic of your flow needs to be adjusted. Looping through each row of your Excel table and running the Get Items action as well as a condition check is inefficient.

It's hard to see the full logic of your flow with the screenshots you've shared. Toggle off the New Designer and click each action to expand it. Upload a screenshot of your flow in edit mode.

I can only assume that you are wanting to cross-check your Excel table to the data in your SP list. If this is the case, you may be interested these YT Tutorials:
