Hi Lakshmi,
Try below formula in B2 and copy down:
=DATEVALUE(MID(SUBSTITUTE(TRIM(A2)," ","/"),FIND("/",SUBSTITUTE(TRIM(A2)," ","/"))+1,FIND("|",SUBSTITUTE(SUBSTITUTE(TRIM(A2)," ","/"),"/","|",2))-FIND("/",SUBSTITUTE(TRIM(A2)," ","/"))-1)&"-"&LEFT(SUBSTITUTE(TRIM(A2)," ","/"),3)&"-"&RIGHT(SUBSTITUTE(TRIM(A2)," ","/"),4))
Than custom format the date as per your choice.
Regards,
