Yes, named ranges can be used across different worksheets in an Excel workbook, but with some limitations:

* Default Scope: By default, a named range applies only to the worksheet where it's created. This means you can't directly reference a named range from another sheet by its name alone.

Here are two ways to use named ranges across worksheets:

1. Full Reference with Worksheet Name: You can include the worksheet name along with the named range in your formula. For example, if you have a named range called "TotalSales" on Sheet1, you can reference it in a formula on Sheet2 like this: `=Sheet1!TotalSales`.

2. Define Scope as Workbook: When creating the named range, you can set its scope to the entire workbook. Here's how:
- Select the cell range you want to name.
- Go to the "Formulas" tab.
- Click "Define Name" in the "Defined Names" group.
- In the "New Name" dialog box, enter a descriptive name for your range.
- Under "Scope," choose "Workbook" instead of the default "Worksheet."
- Click "OK" to create the named range with workbook scope.

Once you define the scope as a workbook, you can simply use the named range by its name in formulas on any worksheet within the same workbook.

Things to Consider:

* Using workbook-scoped named ranges can lead to confusion if you have multiple ranges with the same name across sheets. It's recommended to use descriptive and unique names.
* If you frequently reference named ranges from different worksheets, consider using a consistent naming convention that incorporates the sheet name for better readability (e.g., Sheet1_TotalSales, Sheet2_TotalSales).
