Thanks a lot for your solution.
With your help and the logging module, programming Lua= filters for Pandoc is starting to be fun and I came up with this solution = by myself:

Debugging filters wo= rking on the yaml metadata provided a particular challenge to me:
=

function Meta (= m)
=C2=A0 if FORMAT:match 'docx' then
=C2=A0 =C2=A0 =C2=A0 = =C2=A0 authors =3D m.author[1] .. {pandoc.Str(', ')} .. m.author[2]=

It on= ly handles two and not more authors, but in my case, that's fine.

Your metadata ha= s this structure (hmm... perhaps some of the Inlines are really MetaInlines= , in which case that's a problem with my logging module):

(#) meta Meta {
=C2=A0 author: List[2] {<= br>=C2=A0 =C2=A0 [1] Inlines[3] {
=C2=A0 =C2=A0 =C2=A0 [1] Str "Aut= hor"
=C2=A0 =C2=A0 =C2=A0 [2] Space
=C2=A0 =C2=A0 =C2=A0 [3] Str= "A"
=C2=A0 =C2=A0 }
=C2=A0 =C2=A0 [2] Inlines[3] {
=C2= =A0 =C2=A0 =C2=A0 [1] Str "Author"
=C2=A0 =C2=A0 =C2=A0 [2] Sp= ace
=C2=A0 =C2=A0 =C2=A0 [3] Str "B"
=C2=A0 =C2=A0 }
=C2= =A0 }
=C2=A0 title: Inlines[1] {
=C2=A0 =C2=A0 [1] Str "Test&quo= t;
=C2=A0 }
}

... so I think you = want this filter (MetaInlines isn't an attribute name, and you have to = count the space):

functio= n Meta (m)
=C2=A0 =C2=A0 print(pandoc.utils.stringify(m.author[1][3]))end
