We have some tools that wrap an in-house program which generates an Excel spreadsheet as one of its outputs, and wanted Galaxy to associate the correct mime type so that the user's browser knows how to handle it on view/download.

The advice on the wiki at


appears to be out of date, so instead as a workaround I've edited datatypes_conf.xml and replaced the existing "xls" type:

<datatype extension="xls" type="galaxy.datatypes.data:Data" mimetype="application/vnd.ms-excel" />

This seems to work (in that clicking the eye icon now givens me a download dialogue rather than a server error message). However I'm wondering:

- Would type="galaxy.datatypes.binary:Binary" be a better choice?
- What are the consequences of replacing the original "xls" datatype?
- More generally, is there a way to keep the locally defined datatypes separate from the main
  datatypes_conf.xml file?

Thanks for any advice or comments (& apologies if I've missed anything obvious on the list or on the wiki)

Best wishes, Peter
