[Advanced Excel] Excel can not open the file because the file format or file extension is not valid

I am trying to download my first (basic) Excel file created by "Advanced Excel". As you can see on the following picture I just create a workbook, wrote a text in one cell and get the binary data to an output parameter which is used to download in the front end. The download name is the following: "abc.xlsx".

However when opening  the abc file,  the error appears and Excel is not able to open it.

How can I fix this?

Hi Tom,

Please find attached oml for working solution of basic excel

Best Regards
