Convert Using a Formula

This method shouldn't disturb any text that might be in your list (read the bottom of this section for the exception).

This requires inputting a formula in a column next to the number.

=TRIM(cell_reference)

1. Go to the column next to your number(s) and type =TRIM(A1)
   
   A1 is the cell that contains the number.
2. Once you hit enter, it turns into the complete number:
   
3. Replace the old column of data using copy/paste special. Ctrl + C and then Alt + E + S + V + Enter.

The TRIM() function removes extra spaces from the front and back of a cell in Excel. This will not harm or mess-up any text cells that you might have in your list when you copy the formula down unless those text cells are supposed to have extra spaces around them. If you need to retain extra spaces, you can use UPPER() or LOWER() or PROPER(), though each will change the case of the text.

Convert Using Formatting

This method keeps all of your data in the same place and will not harm any text that might be in your list.

1. Select the cell with the numbers and right-click on them and click Format Cells...
   
   
2. Go to the Number tab and click the Custom category:
   
3. Under where it says Type: input a 0
   
   You should now see the entire number appear just above where you entered the 0.
4. Hit OK and the number in the spreadsheet should now be clearly visible.
   

This is a great method to use; it's simple, fast, and reliable.

Input a Number so it's Never Converted to Scientific Format

If you are entering numbers by hand, you can use this quick tip to prevent them from converting to scientific format:

Type a single quotation mark/apostrophe in front of the number.

Notice the comma in front of the number in cell A5.

When I hit Enter, we still see the entire number.

The apostrophe will still be in the cell, but you will only see it when you go to edit the cell.

Notes

Unfortunately, Excel has limitations when it comes to numbers and sometimes Excel thinks it's helping us when, really, it is just being a pain in the neck. This tutorial is meant to show you a few methods for getting your numbers back.
