FormReturn has the ability to create a report from an XML export from Captured Data using XSL-FO templates.
To use this feature, first export the XML file from a test publication of the form you made (click publiation -> publication name -> export -> XML export tab). Use that XML as the basis for designing your XSL-FO file. We recommend using XF Designer from Ecrion. Once you have created the XSL-FO template in XF Designer, select it when you go to export a PDF report (PDF export tab in the export dialog).
FormReturn uses Apache FOP as its XSL-FO processor. If you write an XSL-FO template, be sure that it is compatible with FOP.
