Python Requests Post Excel File

Posting an Excel file using Python requests is straightforward, and it can be done in a few simple steps.

Step 1: Import the Required Libraries

Before we can start sending requests, we need to import the necessary libraries. In this case, we will be using the requests and pandas libraries. The requests library will be used for sending HTTP requests, while pandas will be used for reading the Excel file.

import requests
import pandas as pd

Step 2: Read the Excel File

The next step is to read the Excel file that we want to post. This can be done using the pandas read_excel() method.

df = pd.read_excel('file.xlsx')

Step 3: Convert the Excel File to Bytes

Since we will be posting the Excel file as bytes, we need to convert it first. This can be done using the to_bytes() method.

excel_file = df.to_excel(index=False)
excel_bytes = excel_file.getvalue()

Step 4: Send the Request

Finally, we can send the POST request with the Excel file attached. We need to specify the headers and payload in the request, with the payload being the Excel file converted to bytes.

url = ''
headers = {'Content-Type': 'application/'}
payload = {'file': ('file.xlsx', excel_bytes)}
response =, headers=headers, files=payload)

The above code will send a POST request to the specified URL with the Excel file attached. The Content-Type header specifies that the file is an Excel file, and the files parameter in the request specifies the file to be sent.

There are other ways to accomplish this task as well. For instance, we can use the open() method to read the Excel file and then post it using requests. Here's an example:

with open('file.xlsx', 'rb') as f:
    response =, headers=headers,

This code reads the Excel file using the open() method and then posts it using requests.
