How do I separate a comma-separated list into two columns in Excel?

I have a long, comma-separated list which looks like this in Excel:

401.50,0.027  
402.00,0.028  
402.50,0.029  
403.00,0.031  
403.50,0.032  
404.00,0.034  
404.50,0.037  

Is there a simple way to convert this into two separate columns? There are over 800 values, and I am really not looking forward to separating them all individually.

Have you tried using Text to Columns?

1. Highlight the column that contains your list.
2. Go to Data > Text to Columns.
3. Choose Delimited. Click Next.
4. Choose Comma. Click Next.
5. Choose General or Text, whichever you prefer.
6. Leave Destination as is, or choose another column. Click Finish.

You could also use two formulas in two separate columns.

To get the values to the left of the comma:

=0+LEFT(K1,FIND(",",K1)-1)

To get the values to the right of the comma:

=0+RIGHT(K1,LEN(K1)-FIND(",",K1))

where K1 contains the initial string, such as 401.50,0.027

** 0+ before the formulas converts the extracted substrings to numerical data.

Copy/Paste the text into a text editor Replace all space characters with carriagereturn/linefeeds Save as a TXT file. Open the file in Excel.
