Transpose Collection"" action creates two columns(Fields) in Output Collection i.e Name(Text) and Value(text). In the Name column you will get Column names and in the Value column you will get respective values of Input collection.
e.g if you have collection name ""Input col"" having one field ""Id"" (with three values 1,2,3) ..and another empty collection called ""Output col"" ..after performing Transpose Collection action your ""Output col"" will get two Fields ""Name"" and ""Value""... and it will look like
Name Value
Id 1
Id 2
Id 3
Hope this helps 🙂
