Hi Goyo, I’m new to streamlit. Not sure if I understand your reply.
So, you mean that a web-based app by streamlit does not allow generating a file due to safety reasons?
Or something else?

I don’t mean anything like that, I am just asking you a question.

what makes you think that the app “fails to generate an excel file”?

Do you understand the question?

I dig into some discussion and found this:

Get path from file_uploader()

Other than uploading to cloud, there is also the very useful tempfile module including the NamedTemporaryFileclass. Something along the lines of: from tempfile import NamedTemporaryFile import streamlit as st uploaded_file = st.file_uploader("File upload", type='csv') with NamedTemporaryFile(dir='.', suffix='.csv') as f: f.write(uploaded_file.getbuffer()) your_function_which_takes_a_path(f.name) Should work.

Thanks Caroline, forget my request and thanks ~
