Hey @Rakesh007 

I faced a similar issue a few months ago with this library:

https://github.com/nightscape/spark-excel/discussions/834

I assume you’re currently using Unity Catalog — it seems to introduce some compatibility issues, and unfortunately, the library hasn’t been updated to address them yet.

Anyway make sure that you got it avaiable in allowed JARs/Init Script  inside Catalog>Metastore>allowed JARs/Init Script

Hope this helps! 🙂
