Finding and deleting Types of business entity from organization names

Hi there,

I have a list of organizations around the  globe.  Some of them are ended with types of their business entity, e.g. Star LLC, Moon LTD.

Is there a smart way to delete these business entities endings?

I used the conditional formatting columns, find & replace, the Substitute function. But there should be more sophisticated way to solve it.

My challenges are:

• There are more than 30 types of business entities, including variations with commas, dots, spaces. 
• Most probably, I don't know about all possible options.
• Sometimes an organization name contains INC e.g., but this is not the business entity, just a part of an organization. I don't  want to replace anything in this case.
• I want to delete commas, but some organizations contain them as a part of their name.
