I need to isolate all the characters in a cell prior to the last
space.
Can anyone tell me how to find the the posistion of the last space in
the cell?

This is an example of my data:

CompanyA
Company B
CompC

The output I want from my formula is:

CompanyA
Company B
CompC

I'm trying use a LEFT formula knowing the position of the last space;
but other suggestions are welcome.
