Using Text to Columns Fastest way to Delimit
First, I want to say all of the previous suggestions are terrific. But for the sake of covering all bases and methods, heres another. Its only if youre doing Text To Columns ONE TIME and dont plan on adding any additional data:
Utilizing the EDIT>>REPLACE function, simply put a space in the FIND field, then say a comma or semicolon in the REPLACE field. Then Select REPLACE ALL. Beware it will replace ALL blanks in EVERY column with the substituted character unless you choose one at a time (FIND NEXT). Another alternative is if the data in the column is unique such as "2009 123456 ..." then you can FIND "2009 " and REPLACE with "2009,"
This is of course the most rudimentary approach but its fast, easy, and you dont have to worry about formulas and syntax errors, especially on a ONE TIME conversion. Good Luck.
