This is the technique I ve used with great success    TRIM RIGHT SUBSTITUTE A1       REPT      100    100     To get the first word in a string  just change from RIGHT to LEFT   TRIM LEFT SUBSTITUTE A1       REPT      100    100     Also  replace A1 by the cell holding the text

To add to Jerry and Joe s answers  if you re wanting to find the text BEFORE the last word you can use    TRIM LEFT SUBSTITUTE TRIM A1        REPT      LEN TRIM A1      LEN SUBSTITUTE TRIM A1        REPT      LEN TRIM A1     -LEN TRIM A1       With  My little cat  in A1 would result in  My little   where Joe and Jerry s would give  cat   In the same way that Jerry and Joe isolate the last word  this then just gets everything to the left of that  then trims it back

I also had a task like this and when I was done  using the above method  a new method occured to me  Why don t you do this    Reverse the string   string one  becomes  eno gnirts    Use the good old Find  which is hardcoded for left-to-right   Reverse it into readable string again    How does this sound
