# [Fixed!] Excel SUM Formula Is Not Working and Returns 0 (3 Solutions)

To explore the solutions, use the following dataset that represents some ordered Smartphones and their Quantity.

### Issue 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

Steps:

• Select the cells.
• Click on the error icon.
• Select Convert to Number from the Context menu.

The values will be changed to numbers and the SUM formula should work properly.

#### Solution 2 – Apply Text to Columns Wizard

Steps:

• Select the cells C5:C9.
• Go to Data, then Data Tools, then Text to Columns.
• Soon after a dialog box will open up.

• Check Delimited.
• Press Next.

• Mark Tab and press Next.

• Mark General in the last window.
• Press Finish to confirm.

Then should provide the proper output from the SUM formula.

#### Solution 3 – Apply Paste Special Command

Steps:

• Copy any blank cell.

• Select the cells and right-click.
• Choose Paste Special from the Context menu.

• In the Paste Special dialog box, mark All from the Paste section and Add from the Operation section.
• Finally, just press OK.

This should fix the issue.

#### Solution 4 – Use the VALUE Function

Steps:

• Add a helper column D.
• Write the following formula in Cell D5:
`=VALUE(C5)`
• Hit Enter.

• Use the Fill Handle tool to copy the formula throughout column D.

• Use the SUM formula on the helper column and you should get the expected result.

### Issue 2 – Wrong 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. While this doesn’t happen in Excel 365, it can occur in some earlier versions.

Solution:

Always keep the calculation mode to Automatic:

• Click as on Formulas
• Go to Calculation Options
• Select Automatic from the drop-down.

### Issue 3 – Non-Numeric Characters

If the cells contain non-numeric characters with the numbers then also you will get zero from the SUM formula.

Solution:

You can remove them manually but it’s not feasible for a large dataset. If you know which character is the problem, using the Find and Replace tool will work.

Steps:

• Select the data range C5:C9.
• Press Ctrl + H to open the Find and Replace.
• For the example, type comma (,) in the Find what box and keep the Replace with box empty.
• Press Replace All.

The tool removes all commas (in the example) and the SUM formula has worked.

1. None of these things work (I tried them all and then some). If I highlight the cells, the summary ribbon at the bottom correctly calculates the sum. But SUM and SUMPRODUCT return zero.

I’ve turn auto calculate off and on

• Hello, HPOTTER.
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.

2. 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.

• Hello JK,
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:
=TRIM(SUM(C5:C9))

The TRIM function will remove all extra spaces. I hope, it will help you.

• Hello MAHIN,

Greetings! We appreciate you contacting us and leaving a comment on our Excel blog post with your query. We appreciate your interest and are available to help.

First of all, you have inserted a leading zero by any of the following means:

• Converting a number into a Text for adding the leading zero

Now, there could be a few reasons why the SUM function in Excel is failing to deliver any results for your data. Here are some recommendations to aid in troubleshooting the issue:

• The cell is previously formatted as Text. After converting them into the Number from Home tab the problem can still persist.

• Try to copy your cells and paste them into the new destination. After pasting it in the new cells Trace Error button will appear. Click on that button and select Convert to Number.

• Here is the final output after converting it to a number.

• Look for hidden characters or spaces: On occasion, Excel may fail to recognize values in the cells as numbers because of hidden characters or trailing spaces. Use the CLEAN feature to get rid of any concealed characters. For instance, if your data is in cell A1 and you want to clean it up, you can use the formula “=CLEAN(A1)” in another cell, and then use the SUM function on the cleaned values.
• Look for any mistakes in other cells: The SUM function may occasionally return null if other cells in the range you’re trying to sum include errors like #VALUE! or #DIV/0!. Examine the other cells in the range, and correct any mistakes you find.

You should be able to fix the Excel SUM function returning null problem using the abovementioned techniques. I’ll be pleased to help you further if you can give me more information or a sample of your Excel sheet if the issue continues.

7. None of them work but I solved the problem. I noticed a blank space before the number. I used Find and Replace. Find the space and replace it with nothing. It is now adding it.

Dear Jess

Thanks for your comment! Only leading spaces typically don’t affect the SUM function in most Excel versions. However, leading spaces can indeed cause numbers to be treated as text in some Excel versions like yours. It is great to hear that removing leading spaces resolved the issue for you.

I am sharing another exciting solution for summing numbers with inconsistent spaces using an Excel formula. Please check the following:

Excel Formulas (using SUM, VALUE, and SUBSTITUTE functions): `=SUM(VALUE(SUBSTITUTE(\$B\$2:\$B\$7, " ", "")))`

Hopefully, you will like the solution. Good luck.

Hello Cathy Thompson

Thanks for visiting our blog! We cannot provide an ultimate solution without reviewing your Excel file and being remote. However, you apply several adjustments to the dataset, like checking for non-numeric characters, converting text to numbers, ensuring correct formatting, and checking calculation mode. To clean up your numeric data, you can create a helper numeric column (e.g., real estate tax) and use the formula: `=VALUE(TRIM(CLEAN(B1)))` Lastly, sum the values in the helper columns using the SUM function.

Hopefully, these ideas will help. If you still have difficulties, you can share your problem with the ExcelDemy Forum by attaching your Excel file. Good luck.
