importing files from streamlit app on databricks to dbfs

zoeyazimi — Wed, 21 May 2025 16:04:10 GMT

I am building a Streamlit-based app on Databricks that allows users to:

Upload Excel scenario files
Store them in DBFS (e.g.,/FileStore/SCO/scenarios/)
Trigger a simulation/optimization model using the uploaded/stored file as input to the model
Store the outputs (logs, visualizations, result summaries) in DBFS or Unity Catalog

Issue: When deploying this as a custom Databricks App , I run into restrictions:

I cannot write to /dbfs/...directly from inside the app
dbutils and the Databricks CLI are not available

I wan to know :

What is the correct, supported way to write files from a Databricks App particularly streamline into DBFS?
Is there a built-in API method or recommended workaround?

Here is an example for uploading files to a Volume, a download example is there, too
