In this new walkthrough, we explore how to use the blazing-fast Polars dataframe library in a Dash app, featuring a dynamic Excel file uploader, an interactive map, and a fully filterable Dash AG Grid table.
You’ll learn how to:
✅ Upload and parse Excel files
✅ Filter and sync table data with the map in real time
✅ Use Polars efficiently inside Dash callbacks
This is perfect for anyone looking to move beyond static spreadsheets and toward high-performance, interactive data apps, all in Python.
