Generating list of variations and their corresponding lengths

I upload sound effects to audiojungle and everytime I have more variations in my item I have to list all of them in the description with their corresponding length. That is quite time consuming when you have like 10 variations.
Is there a software that does it autmatically? (Select multiple files - generate “file name” : “file length in min:sec”)
I can ask some dev friends of mine but I believe something like that already exists.
