@Dino Cehic As per the error looks like excel was not created successfully therefore while opening the it is not readable format.
I came across this article while can help you how you can create the excel in azure function. You need to modify the code as per your end but it is for reference to help you whether you are creating the excel file correctly. Once you have created the excel file correctly then you can use the storage SDK to storage that file in storage account.
