3 Fixes: Excel Sum Formula Is Not Working and Returns 0
To explore the solutions, we’ll use the following dataset that represents some ordered Smartphones and their Quantity.
1. Number Stored As Text
Have a look that I have used the SUM function here to find the total quantity but it returned zero. Why is it happening?
The reason is that I stored the numbers as text values. That’s why there are green triangular icons in every cell. So the SUM formula recognized no numbers and that’s why returned zero.

Solution 1: Use Convert to Number
First, I’ll use the Convert to Number command to convert the text values into numbers. It is one of the easiest ways.
- Select the cells.
- Then click on the error icon.
- Later, select Convert to Number from the Context menu.
Now see, we got the values as numbers and the SUM formula worked properly.
Solution 2: Apply Text to Columns Wizard
Another useful solution is to use the Text to Columns Wizard.
- Select the cells C5:C9.
- Then click as follows: Data ➤ Data Tools ➤ Text to Columns.
- Soon after a dialog box with 3 steps will open up.
- In the first step, mark Delimited.
- Later, press Next.
- After that mark Tab and press Next.
- Mark General in the last step.
- Finally, just press Finish.
Then you will get the proper output from the SUM formula as it should be.

- First, copy any blank cell.
- Next, select the cells and right-click your mouse.
- Then select Paste Special from the Context menu.
- After appearing the Paste Special dialog box, mark All from the Paste section and Add from the Operation section.
- Finally, just press OK.
And yes! We are done.
Solution 4: Use the VALUE Function
Lastly, I’ll show how to use the function to solve the problem. We’ll use the VALUE function in this regard.
- First, add a helper column.
- Then write the following formula in Cell D5–
- Hit the Enter button.
- Next, use the Fill Handle tool to copy the formula.

2. Change Calculation Mode
If you keep the calculation mode in Manual mode then it might be a reason and for that Excel SUM formula is not working and returns zero. But it doesn’t happen in the latest version- Excel 365, which can happen in some earlier versions.
Always keep the calculation mode to Automatic.
- Click as follows to set Automatic mode: Formulas ➤ Calculation Options ➤ Automatic.

3. Remove Non-numeric Characters
If the cells contain non-numeric characters with the numbers then also you will get zero from the SUM formula. Take a look, there are commas with the numbers in my dataset here.
You can remove them manually but it’s not feasible for a large dataset. So using the Find and Replace tool is the best option.
- Select the data range C5:C9.
- Press Ctrl + H to open the Find and Replace
- Then type comma (,) in the Find what box and keep the Replace with box empty.
- Finally, just press Replace All.
That tool removed all the commas and the SUM formula is working fine now.

Thanks for your feedback. We think your problem is very specific which is difficult to identify without the file. So, if you would share your Excel file with us then we could find out the issue and hope, we could give you a solution.
So these did not help, but my issue as it turned out is the data had an added space after the number, and excel did not know how to handle it.
Thanks for your feedback. Your problem is quite rare and unique. So it’s difficult to detect this type of problem without the user’s Excel file. If you would share your file with us, then hopefully we could detect the issue and could give you the exact solution. But temporarily we are suggesting you use the SUM function within the TRIM function, we are showing you a sample formula:
The TRIM function will remove all extra spaces. I hope, it will help you.
