In Gridview Is it possible to create a calculated column with concatenated upc numbers for each of my SKU numbers?

I would like them to be separated in a cell with ", " if possible.

Right now I have 17000 sku's that output to 34000 rows and then have to run a script with the exported .csv in google sheets to concatenate and bring it back down to 17000 rows.

eg.
SKU----------Description------Barcodes
123456------Item123-----------65547899, 65541233, 54432166, 15895475
321654------Item321-----------78945556, 45667789, 14785248, 98778845, 45777456

Thank you in Advance
