Hi @rieckl,   There is a topic about importing data in the FAQ here: How do I import data from a raw data file, a Microsoft Excel worksheet, or a DBMS file?  Click on Snippets at the top to view instructions for using the Import XLSX File snippet.  In Step 2 of the instructions, there is an explanation for Line 3 of the snippet that shows examples of how to specify the XLSX filename.   Hope that helps! thanks, Jennifer   ...
