... one of the columns has multiple values separated with a comma like an array. ... unwind the array so each value of the array is on a separate line and all other fields are duplicated or carried with it ... [from the OP]

Admittedly not the clearest specification. I was focusing on the "... all other fields are duplicated or carried with it ..." part, which I took to mean that some other fields with commas might be printed.

... mongo documentation of $unwind does what I'd like ...

I don't understand what this means. Is "mongo" a thing?
