Question details

The user encounters a named-range conflict prompt asking to use the existing name or enter a new one when attempting to copy multiple worksheets within the same workbook.

Product: Excel
Device & OS: not provided
Scenario: Copying multiple worksheets within a single workbook that contains existing defined names.
Observed behavior: The spreadsheet application displays a recurring prompt stating that a defined name already exists, typically caused by duplicate, hidden, or globally-scoped names.

Before you start

Create a secure backup copy of your workbook before modifying any defined names, as altering or deleting name scopes can potentially break existing formulas.

Solution 1Recommended

Inspect and Resolve Name Conflicts Using Name Manager

Use the built-in Name Manager to identify, edit, or remove duplicate defined names that trigger the conflict prompt.

When you copy a worksheet containing workbook-scoped defined names, the application detects a conflict. Resolving these duplicates directly in the Name Manager will stop the prompt from appearing.

Open Name Manager

Navigate to the Formulas tab on the top ribbon and click on Name Manager.

Filter and Inspect Names

Look through the list for any names that reference the worksheets you are trying to copy. You can use the Filter button to narrow down names with errors.

Edit or Delete Conflicts

Select the conflicting name and click Edit to change its scope, or Delete if the name is no longer needed in the workbook.

Scope Limitations: In some versions, you cannot change the scope of an existing name directly. You may need to delete the name and recreate it with the correct worksheet-level scope.

Frequently Asked Questions

Why does Excel keep saying the name already exists?

This happens when you copy a sheet that has a named range with a 'Workbook' scope. The software recognizes that copying the sheet would create a duplicate name in the same scope, thus triggering the prompt.

How do I find hidden defined names in my workbook?

Hidden defined names do not appear in the standard Name Manager. You typically need to use a short VBA macro to set the 'Visible' property of all names to True, allowing you to view and delete them.

Will deleting a named range break my existing formulas?

Yes, if a formula directly relies on that specific named range, deleting it will result in a #NAME? error. Always verify where the name is referenced before removing it.
