How to Clean Up Defined Names in Excel

Names & Errors · Updated June 2026

Defined names make formulas readable, but they pile up over the life of a workbook. Copied sheets, imported ranges, and deleted data leave behind duplicates, stray scopes, and broken references that slow Excel down and clutter your dropdowns. Here is how to take stock of the names in a workbook and clean them up properly.

See every name with the Name Manager

Before you delete anything, get a complete picture of what is defined in the workbook.

  1. Press Ctrl+F3 to open the Name Manager, or go to the Formulas tab and click Name Manager.
  2. Review the Name, Value, Refers To, and Scope columns for every entry.
  3. Click the Filter button to narrow the list to names with errors, names scoped to the workbook, or names scoped to a specific sheet.
  4. Sort by the Refers To column to spot duplicates and ranges that no longer make sense.

Know what is safe to remove

A name is usually safe to delete when its Refers To value shows a #REF! error, when it duplicates another name that points at the same range, or when nothing in the workbook references it anymore. Be careful with names used in charts, data validation lists, conditional formatting, and PivotTables, because those references are easy to miss. When in doubt, note where a name is used before removing it.

Delete and rename in the Name Manager

The Name Manager lets you remove a name by selecting it and clicking Delete, and you can Ctrl-click to select several rows at once before deleting. To rename, select a name, click Edit, and change the Name field. The catch is that editing values and scopes still happens one entry at a time, and the dialog has no search box, so a workbook with hundreds of names becomes tedious to maintain.

FAQ

How do I open the Name Manager in Excel?

Press Ctrl+F3, or go to the Formulas tab and click Name Manager. It lists every defined name in the workbook along with its value, what it refers to, and its scope.

Will deleting a defined name break my formulas?

Yes, if a formula still uses that name. After you delete it, any formula that referenced the name returns a #NAME? error. Check the Refers To column and search your formulas for the name before removing it.

Can I delete many defined names at once?

In the Name Manager you can Ctrl-click multiple rows and delete them together, but you cannot rename or edit them in bulk. ModelMint's Name Scrubber lets you filter and act on many names at once, including renaming and hiding.
