How to remove duplicated in the same cell

ll1100000

How can I remove the repeated information in a same cell?

You can see the information were separated by ","  but some of them are repeated

Foe example,  in the last line, the size description column has "ASST" and "XS" repeated twice.

How can I remove one of them and keep the unique information. 

Thank you.

How many fields are there in your file?  5, 10, 50?  If it's just a few, you could just repeat and then join back.  Or if it's many, a macro could be built out of the workflow.  Here's all of the data you provided, cleaned up.
