Yes, it is possible to sum a column of numbers based on the background color of the cells in Excel 2007. Here are the steps to do so:
- Select the cell where you want to display the sum of the green cells.
- Click on the "Formulas" tab in the ribbon.
- Click on the "More Functions" dropdown menu and select "Statistical".
- Select "SUMIF" from the list of functions.
- In the "SUMIF" dialog box, enter the range of cells you want to evaluate in the "Range" field.
- In the "Criteria" field, enter the formula
Formula:
=CELL("color",A1)=204
, where "A1" is the first cell in the range you want to evaluate. This formula checks if the cell background color is green (which has a color code of 204). - In the "Sum_range" field, enter the range of cells you want to sum if the criteria is met.
- Click "OK" to close the dialog box and display the sum of the green cells in the selected cell.
Note that this formula only works for cells with a solid fill color. If the cells have a pattern or gradient fill, this formula will not work. Also, if you want to sum cells with a different color, you will need to change the color code in the formula accordingly.
