Deleting Duplicate Entries based on specific column

[med219]

Hi all,

I am relatively new used to Sharepoint and Power Automate. At the moment I'm trying to create an HTML table or an array (whichever would be easier) and populate it using the data from just one column of a sharepoint list. From there, I'd like to find and delete duplicate entries based on that column, which in my case will be email addresses. From that point I plan to take the final/new list of email addresses and sent out an email to everyone on it. That portion I think I'll be able to figure out once I've done the first part. I have been working at it unsuccessfully for a while, so any help and/or guidance will be greatly appreciated.

Hello,

Check out my POC i just created for you.

Here is my SP list for Fruit and QTYInitialize empty Array, use the get items SP actionAdd a loop to loop through the SP list. Use a compose action to add the column item to a Array. using the append to array variable actionUse union() to remove all duplicates on an array by selecting the array twice in the parameters.. You can then use split() to split each unique item

Union expression:

union(variables('MyArray'),variables('MyArray'))

Split Expression:

split(body('Join'),',')

Hope this helps..

Here is my successful run

Thanks so much for the help. What you've provided me works pretty well, I can see that it creates the array without the duplicates so I'm getting somewhere. I run into some issues after that point. The split is not working for me, but the current array is broken down as I'd like so I'm not sure if I need that step to then create an HTML table or put it in some other format that will allow me to email the list. Right now it emails as "xxxxxxxxx@website.com, xxxxxxxxxxx@website.com, ..." which isn't horrible but doesn't look very good/ isn't easy to read through. I believe your answer may be my solution, I just need to work with it a little more.
