IT is possible to export to a tab, csv or one of several other file formats using export records. WHen you set this up, if the relationships you have defined support it, you can export from multiple related tables to do so.
How easy or difficult this is to do, and eactly how you want to set this up will depend on the relationships that link the tables.
Worked fine with exporting it as an excel file - the others did not work as they didn't export the field names for the related file. There was a unique ID for an individual in both - pretty simple item.
You might see if Merge works as an export file format as that will include the field names.
