Hi @Hubert Dudek​,

​

Pandas API doesn't support abfss protocol.

You have three options:

​

• If you need to use pandas, you can write the excel to the local file system (dbfs) and then move it to ABFSS (for example with dbutils)
• Write as csv directly in abfss with the Spark API (without using pandas)
• Write the dataframe as excel with the Spark API directly in abfss with a library like https://github.com/crealytics/spark-excel. (without using pandas)

​

Thanks.
