python - Use Flask to convert a Pandas dataframe to CSV and serve a download -

-

i have pandas dataframe in flask app want return csv file.

return response(df.to_csv())

the problem output appears in browser instead of downloading separate file. how can change that?

i tried following gave empty output.

response = make_response(df.to_csv()) response.headers['content-type'] = 'text/csv' return response(response)

set content-disposition tell browser download file instead of showing content on page.

resp = make_response(df.to_csv()) resp.headers["content-disposition"] = "attachment; filename=export.csv" resp.headers["content-type"] = "text/csv" return resp
