如何在 Python 中從 Excel 文件中刪除工作表

One of the fundamental characteristics of maintaining a spreadsheet in order and function is deleting a worksheet. Whether it be Microsoft Excel or Google Sheets, deleting sheets will help clean out unessential or outdated sheets to streamline the workbook, declutter data, and improve clarity. This could be useful when consolidating information, updating reports, or preparing files to share and present. In Excel, this can typically be done by right-clicking on the sheet's tab and selecting the delete option.

Advanced users can do this much more efficiently by running automation scripts in VBA or Python, which is invaluable for massive datasets or repetitive tasks. Knowing how to delete a sheet will save you from having a cluttered spreadsheet with irrelevant information that is much more difficult to navigate. This functionality will also make you more efficient and productive when handling data.

How to Remove a Worksheet from an Excel File in Python

  1. Install the IronXL library using pip.
  2. Import Workbook from IronXL.
  3. Load your Excel file using Workbook.Load.
  4. Identify the name or index of the worksheet to be removed.
  5. Delete the sheet using the RemoveWorkSheet() method.
  6. Save the updated Excel file with SaveAs.
  7. Open the new file and confirm the changes made.

Remove Excel Files with IronXL for Python

Here's a sample Python code snippet demonstrating how to remove and save a worksheet from an Excel workbook using the IronXL library:

from ironxl import *
print('Process started')

# Load the Excel workbook
workbook = WorkBook.Load("example.xlsx")

# Remove a sheet by name
workbook.RemoveWorkSheet("Sheet1")

# Save the modified workbook
workbook.SaveAs("modified_example.xlsx")

print('Process completed')
from ironxl import *
print('Process started')

# Load the Excel workbook
workbook = WorkBook.Load("example.xlsx")

# Remove a sheet by name
workbook.RemoveWorkSheet("Sheet1")

# Save the modified workbook
workbook.SaveAs("modified_example.xlsx")

print('Process completed')
PYTHON

Explanation

  • Importing IronXL: The code imports the Workbook class from the IronXL library. This class provides methods to load, modify, and save Excel workbooks.
  • Loading the Workbook: The Workbook.Load method opens an Excel file named example.xlsx, storing it in the variable workbook.
  • Removing a Worksheet: The RemoveWorkSheet method deletes a specified sheet by name (e.g., "Sheet1") from the workbook, keeping other sheets intact.
  • Saving the Modifications: The SaveAs method saves the modifications to a new file modified_example.xlsx, leaving the original file unchanged.
