Hello: I'd like to know if it's possible to use JR to create a generic designt to export any query to xlsx without need to specify field names and formats. JR receives a query (which can cotain a variable number of fields) and export it to xlsx as a single sheet, no pages. Example: select name, sn, age, address from table1.... select computer, cpu, memory, .... from table2.... In both cases, the same report generates an xlsx file, one sheet, no paged, with the fields specified as cell titles in the query. Thanks
