openpyxl 与 pywin32 与其他库：在 Excel 中复制并粘贴包含 =IMAGE() 的单元格的值

Question

我正在尝试在 Excel 中复制并粘贴包含公式 =IMAGE(Url) 的单元格的值。结果是嵌入单元格中的图像，并且不再链接到 URL。

我可以使用 pywin32 使用以下脚本来完成此操作：

ws.Range(f"C2:C{last_row}").PasteSpecial(Paste=win32.constants.xlPasteValues)

鉴于我的目标是在 Azure Function App 中自动化整个脚本，我知道 pywin32 不是理想的解决方案？是否有使用 openpyxl 或其他库的上述脚本的等效项？

谢谢！

Answer 1

下面的示例代码使用Python中的

openpyxl

库来处理Excel文件并用URL替换图像公式。函数

paste_image_values

加载 Excel 工作簿，迭代特定单元格，从图像公式中提取 URL，并将公式替换为 URL。

from openpyxl import load_workbook
import requests
from io import BytesIO
from PIL import Image

# Load the Excel workbook
workbook = load_workbook("C://Users//v-sapujari//Book1.xlsx")
ws = workbook.active

# Iterate through the cells
for row in ws.iter_rows():
    for cell in row:
        if cell.data_type == 'f' and cell.value.startswith('=IMAGE'):
            # Evaluate the formula to get the image URL
            url = cell.value.split('(')[1].split(')')[0]

            # Fetch the image from the URL
            response = requests.get(url)
            image = Image.open(BytesIO(response.content))

            # Save the image to a file (or do whatever you want with it)
            image_file_name = f'image_{cell.row}_{cell.column}.jpg'
            image.save(image_file_name)

            # Set the cell value to the image file name
            cell.value = image_file_name

# Save the modified workbook
workbook.save('modified_excel_file.xlsx')

它从 Excel 文件中提取图像，其中图像 URL 被指定为公式，然后将这些图像保存在本地并使用本地图像文件名更新 Excel 文件。

使用http触发azure函数。使用的包装

azure-functions

、

openpyxl

、

requests

和

Pillow

• 我使用 link 作为 IMAGE 功能

import azure.functions as func
import logging
from openpyxl import load_workbook
import requests
from io import BytesIO
from PIL import Image

def process_excel():
    # Load the Excel workbook (Replace the file path with the appropriate location)
    workbook = load_workbook("C://Users//Book1.xlsx")
    ws = workbook.active

    # Iterate through the cells
    for row in ws.iter_rows():
        for cell in row:
            if cell.data_type == 'f' and cell.value.startswith('=IMAGE'):
                # Evaluate the formula to get the image URL
                url = cell.value.split('(')[1].split(')')[0]

                # Fetch the image from the URL
                response = requests.get(url)
                image = Image.open(BytesIO(response.content))

                # Save the image to a file (or do whatever you want with it)
                image_file_name = f'image_{cell.row}_{cell.column}.jpg'
                image.save(image_file_name)

                # Set the cell value to the image file name
                cell.value = image_file_name

    # Save the modified workbook
    workbook.save('modified_excel_file.xlsx')

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    # Process the Excel file
    process_excel()

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
             status_code=200
        )
