Duplicate Rows - add row in Excel table when new email arrives

Connected Apps:

Hello Everyone,


I am running into some troubles with a Power Automate Flow that I have created and I couldn't find an existing solution to my particular problem. I would greatly appreciate any help or suggestions with this. 



Adds duplicate entries in excel table when new email arrives.



My division books hotels for employees daily and I do the expenses reports for these bookings. The hotel confirmation emails get sent to a distribution group that then removes the price from these emails before sending them to the employee directly. 


Currently, my flow takes specific data from the hotel confirmation emails (extracted from the HTML code within the email's body) and adds it to a table in an Excel spreadsheet on my OneDrive. Ever since I built this flow, it has always created duplicate entries in the table, which hasn't been a big deal to me because my VLOOKUP formulas still work fine.


However, I now want to make my flow automatically send the confirmation emails to the employees with the price removed (which I have made work), but the duplicate entries cause two emails to be sent out, which I don't want. 


Ideally, I would just like one entry to be added into the Excel table when a new email arrives. I don't know how to get around this and I would appreciate any help in regards to this. Also, If I send a test email to myself with the same information, it only creates one entry. It only creates duplicates when the hotel booking website sends them. I will post some screenshots below.


(The second email in the 'From' section is mine so I can test the flow. The other one is the email of the hotel booking provider.)

Hi, You can use the union function to find duplicate rows. And return only one of them, then you should able to send only a single email. 

please, use union(body('Select'),body('Select')) in compose action
