Break all external links in excel using python

When working with Excel files, it is common to come across external links that can cause issues when sharing or transferring the file. In this article, we will explore different ways to break all external links in an Excel file using Python.

Option 1: Using Openpyxl

Openpyxl is a powerful library for working with Excel files in Python. To break external links using Openpyxl, we can iterate through all the sheets in the workbook and remove any external links found.

import openpyxl

def break_external_links(file_path):
    workbook = openpyxl.load_workbook(file_path)
    for sheet in workbook.sheetnames:
        current_sheet = workbook[sheet]
        for cell in current_sheet:
            if cell.hyperlink:
                cell.hyperlink = None

# Usage

This code snippet uses the Openpyxl library to load the Excel file and iterate through each sheet. For each cell in the sheet, it checks if there is a hyperlink and removes it if found. Finally, it saves the modified workbook and closes it.

Option 2: Using xlrd and xlwt

If you are working with older Excel file formats (.xls), you can use the xlrd and xlwt libraries to break external links. These libraries provide functionality to read and write Excel files respectively.

import xlrd
import xlwt

def break_external_links(file_path):
    workbook = xlrd.open_workbook(file_path)
    new_workbook = xlwt.Workbook()
    for sheet_name in workbook.sheet_names():
        current_sheet = workbook.sheet_by_name(sheet_name)
        new_sheet = new_workbook.add_sheet(sheet_name)
        for row in range(current_sheet.nrows):
            for col in range(current_sheet.ncols):
                cell_value = current_sheet.cell_value(row, col)
                new_sheet.write(row, col, cell_value)

# Usage

This code snippet uses the xlrd library to open the Excel file and iterate through each sheet. It then uses the xlwt library to create a new workbook and copy the contents of each cell to the new workbook. Finally, it saves the modified workbook.

Option 3: Using Pandas

If you prefer working with dataframes, you can use the Pandas library to break external links in an Excel file. Pandas provides a convenient way to read and write Excel files while maintaining the structure of the data.

import pandas as pd

def break_external_links(file_path):
    df = pd.read_excel(file_path)
    df.to_excel(file_path, index=False)

# Usage

This code snippet uses the Pandas library to read the Excel file into a dataframe. It then writes the dataframe back to the Excel file, effectively breaking any external links. The index=False parameter ensures that the index column is not included in the saved file.

After exploring these three options, it is clear that using Openpyxl (Option 1) is the most comprehensive and efficient solution for breaking external links in Excel files using Python. It provides direct access to the cells and hyperlinks, allowing for precise modifications. However, the choice ultimately depends on the specific requirements and constraints of your project.
