在从 SharePoint 文件夹中读取 Excel 文件并将其转换为 Pandas DataFrame 的过程中，可以借助 `office365-python-client` 库与 SharePoint 进行交互，并使用 `pandas` 读取 Excel 数据。以下是详细步骤和代码示例。 ### 从 SharePoint 读取 Excel 文件并转换为 Pandas DataFrame #### 1. 安装必要的库 确保以下 Python 库已安装： - `office365-python-client`：用于与 SharePoint 交互 - `pandas`：用于数据处理 - `openpyxl`：用于读取 `.xlsx` 文件 ```bash pip install office365-python-client pandas openpyxl ``` #### 2. 认证并连接到 SharePoint 使用用户名和密码或 OAuth 进行认证，并连接到 SharePoint 站点。以下示例使用用户名和密码进行认证： ```python from office365.runtime.auth.authentication_context import AuthenticationContext from office365.sharepoint.client_context import ClientContext import io import pandas as pd # SharePoint 站点信息 site_url = "https://your-sharepoint-site-url" username = "your-username" password = "your-password" # 创建认证上下文 ctx_auth = AuthenticationContext(site_url) if ctx_auth.acquire_token_for_user(username, password): ctx = ClientContext(site_url, ctx_auth) web = ctx.web ctx.load(web) ctx.execute_query() print("Authentication successful - Connected to SharePoint site: {0}".format(web.properties['Title'])) else: print("Authentication failed") ``` #### 3. 下载 SharePoint 中的 Excel 文件 通过文件路径获取文件内容，并将其作为二进制流读取： ```python file_url = "/sites/your-site/Shared Documents/your-file.xlsx" # 获取文件内容 file = ctx.web.get_file_by_server_relative_url(file_url) file_content = file.get_content().execute_query() # 将文件内容转换为 BytesIO 对象 file_stream = io.BytesIO(file_content.value) ``` #### 4. 使用 Pandas 读取 Excel 数据 使用 `pandas.read_excel()` 函数从内存中的文件流加载数据： ```python # 使用 Pandas 读取 Excel 数据 df = pd.read_excel(file_stream) # 显示前几行数据 print(df.head()) ``` ### 完整代码示例 ```python from office365.runtime.auth.authentication_context import AuthenticationContext from office365.sharepoint.client_context import ClientContext import io import pandas as pd # SharePoint 站点信息 site_url = "https://your-sharepoint-site-url" username = "your-username" password = "your-password" file_url = "/sites/your-site/Shared Documents/your-file.xlsx" # 创建认证上下文 ctx_auth = AuthenticationContext(site_url) if ctx_auth.acquire_token_for_user(username, password): ctx = ClientContext(site_url, ctx_auth) web = ctx.web ctx.load(web) ctx.execute_query() print("Authentication successful - Connected to SharePoint site: {0}".format(web.properties['Title'])) # 获取文件内容 file = ctx.web.get_file_by_server_relative_url(file_url) file_content = file.get_content().execute_query() # 将文件内容转换为 BytesIO 对象 file_stream = io.BytesIO(file_content.value) # 使用 Pandas 读取 Excel 数据 df = pd.read_excel(file_stream) # 显示前几行数据 print(df.head()) else: print("Authentication failed") ``` ---
