Highlight Partial Match using function

Hello All,

I am having a excel where I have data like below

ABC Corp
ABC Corp LLC
ABC Corp LLC Ltd
XYZ Solutions
XYZ Solution
XYZ Solutions Ltd
XYZ Solutions Corp Ltd

I need to remove all the partial duplicates and have only unique value like the below

ABC Corp LLC Ltd
XYZ Solutions Corp Ltd

I am just a beginner and help me to sort out this.

Attach a sample file file with expected result

It's not clear what you want... but does this look like what you wanted? i suspect not, but you never know!!

(I posted this BEFORE I saw your sheet at post 3)

A18=IFERROR(INDEX($A$1:$A$12,SMALL(INDEX((LEFT($A$5:$A$12,SEARCH(" ",SUBSTITUTE(SUBSTITUTE($A$5:$A$12,","," "),"-"," ")&" ")-1)=LEFT($A$6:$A$13,SEARCH(" ",SUBSTITUTE(SUBSTITUTE($A$5:$A$12,","," "),"-"," ")&" ")-1))*10^10+ROW($A$5:$A$12),0),ROW($A1))),"")
Try this and copy towards down
