I would like to ask for some help to update the SharePoint list from the Excel table stored in SharePoint Document Library.
What is the idea:
Manual trigger button - > Check the excel table if Title matches the SharePoint item title. If yes then Update, if no the create new item.
Flow should also check for blank rows in excel Table and ignore them when updating SharePoint list.
Progress so far:


Condition: length(body('Get_items')?['value'])
And for some reason I can't update the columns I want. I'm trying to update the Price column from excel table but can't select any other than SharePoint values here...

So the main achievement would be to be able to update price, and to only try update ( apply to each ) those rows from excel that match SP list item. Otherwise if I have 1000 empty rows, it will try to loop through them anyway.
Any help would be appreciated. I did search within the forum but I couldn't get answers on these issues.
