Why am I seeing the Name Conflict dialog box in Excel?

If you are seeing the Name Conflict dialog box in Excel, that's because you are trying to copy one or more worksheets to a workbook that has similar named ranges.

Suppose the worksheet that you're trying to copy, and the workbook where want to copy it, both have a named range called InterestRates, Excel will detect this conflict and display the following message:

The name 'InterestRates' already exists. Click Yes to use that version of the name, or click No to rename the version of 'InterestRates' you're moving or copying.

Note: The Name Conflict dialog box will appear for every instance of a conflicting name range.


When you see the above dialog box, you must do one of the following:

  • Click Yes to continue using the conflicting range name in the destination workbook.

    What happens when you click Yes?

    Excel will copy the conflicting name range to the destination workbook. That means you will have two similarly named ranges in your destination workbook.

    Warning: If there are formulas that refer to conflicting named ranges in your workbook, then copying those ranges will affect those formulas and cause errors in the workbook. If you are not familiar with the data in the destination workbook, do not click Yes. Instead click No to rename the conflicting range.

  • Click No to rename the conflicting name range. This displays the following dialog box.

    Rename the conflicted range
    1. In the New name section, enter a new name for the range. The new name will not be accepted if it

      • starts with a letter or underscore,

      • is a cell reference, such as A1, A123, or XFD21,

      • has spaces or characters (\, /, *, [, ], :, ?), or

      • has the same name as another range in the workbook that you are copying to.

    2. Click OK.
