How to download a Pandas DataFrame as a CSV?
Use the st.download_button widget that is natively built into Streamlit. Check out a sample app demonstrating how you can use st.download_button to download common file formats.
Example usage
import streamlit as st
import pandas as pd
df = pd.read_csv("dir/file.csv")
@st.cache_data
def convert_df(df):
return df.to_csv(index=False).encode('utf-8')
csv = convert_df(df)
st.download_button(
"Press to Download",
csv,
"file.csv",
"text/csv",
key='download-csv'
)
