Hey @DiegoPeres This is so great! Your concat expression worked like charm
concat(items('Apply_to_each')?['Title'], ': ',items('Apply_to_each')?['Product1'], ',',items('Apply_to_each')?['Product2'], ',',items('Apply_to_each')?['Remarks'])
I can see the output like this:

I was going to mark your reply as 'Accept as Solution' however then thought to check with you if you somehow also know and help me in outputting the result as shown below:

i.e. each field in a separate line and also if the multiline field can show as multiline instead of showing in 1 line.
Please let me know if this takes time and is not an easy solution. I can mark your reply as the solution and maybe open a new thread.
In any case, THANK YOU! again!
