Array variables - unique values

I am trying to get only the unique values from array variable (of strings) into a list so I can create html and email. Is this possible to get this through an expression?

@prasadvenkat use the 'union' expression to combine the array with itself to get a result of unique values. For example: 

 

union(outputs('myArray'),outputs('myArray'))

 

Hope this helps

What action would you place this formula under?

You can place it wherever you want to display or use the output. The simplest option is to use the 'compose' action. You could also use a variable of type 'array'.

@Achavan It looks like you're trying to wrap your array variable in another array.

 

Remove the array function and just use:

union(variables('Customer Array'),variables('Customer Array'))
