How to Fix Excel SUM Ignoring Decimal Numbers Stored as Text
Question details
The user needs to calculate a total using the SUM function, but the formula is ignoring decimal numbers because they are stored as text.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Calculating accurate numerical totals after importing data, or following an operating system or Microsoft 365 upgrade.
- Observed behavior
- The SUM function returns an incorrect total because it completely ignores any cells containing decimal values that are stored as text strings.
Before proceeding, check if the affected cells have a small green triangle in the upper-left corner, which is Excel's default indicator that a number is stored as text.
Convert Text to Numbers Using Paste Special
Use the Paste Special Multiply feature to mathematically force text strings to convert into actual numeric values.
Simply changing the cell format from 'Text' to 'Number' does not automatically convert the underlying data. Multiplying the cells by 1 forces the application to evaluate the text strings as numeric values, allowing the SUM function to read them properly.
Select any blank cell that is formatted as General, type the number 1, and press Enter.
Select the cell containing the 1 and press Ctrl+C (or right-click and select Copy).
Highlight the entire range of cells containing the decimal numbers that your SUM formula is currently ignoring.
Right-click the highlighted range, choose 'Paste Special' from the context menu. In the dialog box that appears, select 'Multiply' under the Operation section, and click OK.

Frequently Asked Questions
Why does changing the cell format to 'Number' not fix the SUM issue?
Reformatting a cell from 'Text' to 'Number' only changes how the data is intended to be displayed, not how it is actively stored in the software's memory. If a number was initially entered or imported as text, it remains text until a mathematical operation (like multiplying by 1) or a data conversion tool forces it to update.
Can I use a formula to convert text to numbers?
Yes, you can use the VALUE function. For example, typing =VALUE(A1) in an adjacent cell will convert a text string in cell A1 into a true numeric value. You can then use the SUM function on the new column of converted values.
How do I know if my decimals are stored as text?
Numbers stored as text are typically aligned to the left side of the cell by default, whereas true numbers align to the right. Additionally, spreadsheet programs often flag numbers stored as text with a small green triangle in the upper-left corner of the cell.
