使用 ZA7F5F35426B5274117FC923 中的 Pandas 將多頁 excel 文件保存到 Azure Blob 存儲

Question

我正在嘗試在 excel 文件中創建兩張工作表，然后使用 ZA37217F32Z4265B6 中的 Pandas 將其上傳到 Azure Blob 存儲但是，我收到一個錯誤 - “'OpenpyxlWriter' object new_writer 的 Cannot.getvalue()”。

    blob_client = blob_service_client.get_blob_client(container=new_container_name, blob=file_name)

    writer = io.BytesIO()

    summary = pd.DataFrame({"one_val": [1, 2]})
    summary.to_excel(writer, sheet_name="Sheet A", index=False)
    blob_client.upload_blob(writer.getvalue(), overwrite=True)

    writer = io.BytesIO()
    summary2 = pd.DataFrame({"two_val": [3, 4]})

    with pd.ExcelWriter(writer, engine="openpyxl", mode="a") as new_writer:
        summary2.to_excel(new_writer, sheet_name="Sheet B", index=False, encoding="utf-8")
        blob_client.upload_blob(new_writer.getvalue(), blob_type="AppendBlob", overwrite=False)

任何有關此問題的解決方案的幫助表示贊賞。 謝謝

閱讀本文以了解如何將 xlsx 保存到字符串https://xlsxwriter.readthedocs.io/working_with_pandas.html#saving-the-dataframe-output-to-a-string

這用於處理多張紙https://xlsxwriter.readthedocs.io/example_pandas_multiple.html

最后一個例子是

import pandas as pd
import io

# Create some Pandas dataframes from some data.
df1 = pd.DataFrame({'Data': [11, 12, 13, 14]})
df2 = pd.DataFrame({'Data': [21, 22, 23, 24]})

output = io.BytesIO()

writer = pd.ExcelWriter(output, engine='xlsxwriter')

# Write the data frame to the BytesIO object.
df1.to_excel(writer, sheet_name='Sheet1')
df2.to_excel(writer, sheet_name='Sheet2')

writer.save()
xlsx_data = output.getvalue()
