Connect with Libreoffice for adress field, standard letters, (Serien Briefe)


is it possible to connect the contact details from Libreoffice or Openoffice in any way?
I’d like to use the contact details e.g. the address data stored in emClient to create a standard letter written in Libreoffice/Openoffice.

Any idea how to do this in an easy way - e.g. without exporting the address data from em Client to CSV - but with a direct connection between theses two programs?

Thank you for any hint,
