我正在嘗試在一個 excel 檔案中創建兩個作業表，然后使用 Python 中的 Pandas 將其上傳到 Azure Blob Storage。但是，我收到一個錯誤 - “不能 .getvalue() of 'OpenpyxlWriter' object new_writer”。
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
uj5u.com熱心網友回復：
閱讀本文以了解如何將 xlsx 保存到字串 https://xlsxwriter.readthedocs.io/working_with_pandas.html#saving-the-dataframe-output-to-a-string
這用于處理多張作業表 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()
