While you are using **the SUM function**, you might get that itâ€™s not working properly and **returning** **zero** if you donâ€™t know the reasons.

**3 Fixes: Excel Sum Formula Is Not Working and Returns 0**

To explore the solutions, weâ€™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. Thatâ€™s why there are **green triangular** **icons **in every cell. So the **SUM **formula recognized **no numbers** and thatâ€™s why **returned zero**.

**Solution 1: Use Convert to Number**

First, Iâ€™ll use the **Convert to Number** command to convert the **text values** into **numbers**. It is one of the easiest ways.

**Steps:**

**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**.

**Steps:**

**Select**the cells**C5:C9**.- Then
**click**as follows:**Data âž¤ Data Tools âž¤ 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.

**Solution 3: Apply Paste Special Command**

Now letâ€™s use a tricky way- **Paste Special** to convert **Text **into **Number**. It may be helpful in some particular cases.

**Steps:**

- 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, Iâ€™ll show how to use the function to solve the problem. Weâ€™ll use **the VALUE function** in this regard.

**Steps:**

- First, add a
**helper column**. - Then
**write**the following**formula**in**Cell D5**â€“

`=VALUE(C5)`

**Hit**the**Enter button**.

- Next, use the
**Fill Handle**tool to**copy**the**formula**.

- Then use the
**SUM**formula and you will get the expected result.

**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 doesnâ€™t happen in the latest version- **Excel 365**, which can happen in some **earlier versions**.

**Solution:**

Always keep the calculation mode to **Automatic**.

**Click**as follows to set**Automatic**mode:**Formulas âž¤ Calculation Options âž¤ 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.

**Solution:**

You can remove them manually but itâ€™s not feasible for a large dataset. So using the **Find and Replace** tool is the best option.

**Steps:**

**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.

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.

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.
