Sorry to say, but the answer is no. For crystal operational reports (order reports) we get the PDF output. So it cannot be exported to excel using IFS app. But if there are 3rd party tools, you can convert a PDF to excel - I don’t think this is not the way you want. 

This is different for crystal quick reports (ad hoc). We get an RPT output from this and preview it inside a SAP’s crystal runtime plugin. This has some export and save as option. Depending on this plugin version you might have such option to export it as an excel. 

Thank you Rusiru
