Delete Named Ranges

Introduction

If there are too many defined names or named ranges in the Excel files, we have to clear some for they are not referred again.

Remove Named Range in MS Excel

To remove a named range from Excel, you can follow these steps:

1. Open Microsoft Excel and open the workbook that contains the named range.
2. Go to the “Formulas” tab in the Excel ribbon.
3. Click on the “Name Manager” button in the “Defined Names” group. This will open the Name Manager dialog box.
4. In the Name Manager dialog box, select the named range you want to remove.
5. Click on the “Delete” button. Confirm the deletion when prompted.
6. Click on the “Close” button to close the Name Manager dialog box.
7. Save the workbook to retain the changes.

Deletes Named Range using Aspose.Cells for .Net

With Aspose.Cells for .Net, you can remove named ranges or defined names by text in the list.

from aspose.cells import Workbook
import aspose.cells
import os
import pytest
# The path to the documents directory
current_dir = os.path.dirname(os.path.abspath(__file__))
data_dir = os.path.join(current_dir, "data")

# Instantiate a new Workbook
workbook = Workbook(os.path.join(data_dir, "Book1.xlsx"))

# Get all the worksheets in the book
worksheets = workbook.worksheets

# Delete a named range by text
worksheets.names.remove_a_name("NamedRange")


# Save the workbook to retain the changes
workbook.save(os.path.join(data_dir, "Book2.xlsx"))

Note: if the defined name is referred by formulas, it could not be removed . We only can remove formula of the defined name.

Removes Some Named Ranges

When we remove a defined name, we have to check whether it is referred by all formulas in the file. In order to improve peformance of removing named ranges,we can remove some together.

from aspose.cells import Workbook
import aspose.cells
import os
import pytest
# Instantiate a new Workbook
workbook = Workbook("testcase/data/Book1.xlsx")

# Get all the worksheets in the book
worksheets = workbook.worksheets

# Delete some defined names
worksheets.names.remove_names_by_array(["NamedRange1", "NamedRange2"])

# Save the workbook to retain the changes
workbook.save("Book2.xlsx")

Remove Duplicate Defined Names

Some Excel fiels corrupt because some defined names are duplicate. So we can remove these duplicate names to repair the file.

from aspose.cells import Workbook
import aspose.cells
import os
import pytest
# Instantiate a new Workbook
workbook = Workbook("testcase/data/Book1.xlsx")

# Get all the worksheets in the book
worksheets = workbook.worksheets

# Delete duplicate defined names
worksheets.names.remove_duplicate_names()

# Save the workbook to retain the changes
workbook.save("Book2.xlsx")
