Break multipart close polysurfaces into individual polysurface

Hello there, I have received a strange close polysurfaces that contains multiple untouched, closed parts. I am just wondering is there a way that I can break them into individual parts but not by exploding first, then join ? (PS. I know that this strange Polysurface can be archieved by NonmanifoldMerge, is there an Unjoin NonmanifoldMerge?) Thank you

Hello- select the object, run Explode then Join.


Hi Pascal, is there an alternative method ? There are scenarios that I couldn’t explode the geometries then rejoin (overlap surfaces etc) The attached file is a simplified version of what I am doing . Thank you
