Use python extract images from Excel sheets

Use python extract images from Excel sheets

To extract images from Excel sheets using Python, you can use the openpyxl library, which is a popular library for working with Excel files. Here's an example script that demonstrates how to extract images from an Excel sheet:

from openpyxl import load_workbook def extract_images_from_excel(excel_file_path, output_folder): # Load the Excel workbook workbook = load_workbook(excel_file_path, data_only=True) for sheet_name in workbook.sheetnames: sheet = workbook[sheet_name] # Iterate over all drawings in the sheet for drawing_id, drawing in enumerate(sheet._drawings, start=1): if isinstance(drawing, openpyxl.drawing.image.Image): # Extract the image data image_data = drawing.image # Save the image to the output folder image_filename = f"{sheet_name}_image_{drawing_id}.png" image_path = f"{output_folder}/{image_filename}" image_data.save(image_path) print(f"Image extracted: {image_path}") # Example usage excel_file_path = 'your_excel_file.xlsx' output_folder = 'output_images' extract_images_from_excel(excel_file_path, output_folder)

Replace 'your_excel_file.xlsx' with the path to your Excel file and 'output_images' with the desired output folder. This script iterates through all sheets in the Excel workbook, extracts images, and saves them as PNG files in the specified output folder.

Make sure to install the openpyxl library if you haven't already:

pip install openpyxl

Note: The openpyxl library may not be able to extract all types of images (e.g., linked images). This example focuses on embedded images in the Excel file. If your Excel file contains linked images or other types of objects, additional considerations may be needed.
