How to Replace Blank Cells With Value in Excel 2003

1. Select the range of cells that contain the blank cells you want to replace. Do this by clicking on the uppermost cell on the left side, then drag the cursor down to the right until the last cell of the range is highlighted. Not all of the cells in the range have to be blank.
2. Go to 'Edit' on the menu bar and select 'Replace.' A pop-up menu will appear.
3. Leave the 'Find what' box blank to search for blank cells.
4. Enter the value you want to replace the blanks with in the 'Replace with' box. For example, if you want '4' to replace all the blank cells, type '4' (no quotation marks).
5. Click the 'Replace All' button if you want all the blank cells replaced with your value. If you want only certain cells replaced with the value, click 'Find Next' and then click 'Replace' whenever you want the blank cell replaced. If you do not want a certain blank cell replaced, click 'Find Next' to go to the next blank cell.
