I have a cell that has the following data:
For example: (a 3-digit number and then a name)

123 Robert
234 Bill
456 Jane
342 Sue

I want to be able to separate the numbers into one cell and the name into another. Using Excel 2010, how can this be done?

Your help is greatly appreciated.

Steps to take.

1. Save your work sheet as a text file

2. Open up the text file in Excel as a .txt file. You should get the Text Import Wizard.

3. Click "Next" for step 2 of 3. In the area in the upper left hand corner of the dialog box, check on the box that says "Space". That should put a line between the numbers and letters.

4. Click "Next" to format the columns or "Finish" to complete the opening of the file. Your words should be separated by columns

well, there is a method, very easy:
select your range to split, then on Data tab, Data instruments-text to column....
folow the menu, and select your separator.. in you case, it' s a space..
your range is now separated in next columns, each word or numbers in a column

Thank you! It worked great!
