Hi Jonas. I think it is pretty re ent, but newer version of qgis allow this inherently. Iam using version 2.14.2 and have a shape file linked to an excel spreadsheet (using spreadsheet layers plugin to bring in the excel doc) via an id field. I can then just use the linked fields exactly the same way as normal fields in the select by expression tool in the attribute window. I can also categorise the styles by the joined fields. Hope that helps. Damien
