Upload CSV File Using Python Flask And Process It

I have the following code to upload an CSV file using Python FLASK. from flask_restful import Resource import pandas as pd ROOT_PATH = os.path.dirname(os.path.abspath(__file__))

Solution 1:

The (not so aptly named, due to it being one file) files variable contains a werkzeug.datastructures.FileStorage object. This is a file like object (containing a read() method), and as such it is possible to use it directly as input to pandas.read_csv()as seen in the pandas documentation.

Thus, the solution to not save to disk is as simple as:

class UploadCSV(Resource):

    def post(self):
        file = request.files['file']
        data = pd.read_csv(file)
        print(data)
