Pivoting attribute-value pairs so the attributes become headers and the values under them

I need to join one attri-value paired table and one master table that contains the actual attribute name/header. The result is shown in Results window below.. but what I really want is to transpose/pivot the results so the column Right_ATTR_VALUE becomes the headers and ATTR_VALUE becomes the values under their corresponding headers..

Please advise how I can achieve the results I want.

My apology I cannot attach the workflow because the system rejects the content of the attachment doesn't match its file type (yxzp).

Thanks.
