As Keith says, your objective can be reached by writing a program. There are numerous libraries for creating Excel spreadsheet output, adapted to a wide range of programming languages. (Perl, Go, C#, Java, C, ...) There are also some applications intended for "data integration", to shovel and transmogrify data in many ways between many data sources and sinks. For example, Pentahoe's Kettle (aka PDI). It's been awhile since I looked into them, but their capabilities seem to keep growing in response to customer demand (such as yours.)
