It is not possible from Collabora Online to chose Danish as the spelling language in a document loaded from Nextcloud. This a major issue as multiple organizations thru out Europe are investigating ways to leave the US based Office services. Recently a journalist from the weekly paper Ingenøren, targeting Engineers, who in a feature tried to break loose from the US tech companies complained that she could not get Danish spell checking in Collabora Online. She is running a feature to investigate what it takes to leave the US based Office and cloud services. Likewise has a journalist from the danish online media Zetland tried the same with the same result. Both journalists regarded this as a major obstacle to migrate away from their current setup.
My investigation supports this:

Note that the danish dictionary (collaboraoffice-dict-da) is installed and is recognized in the startup of collabora: Here is an extract from the journal log of coolwsd startup:

Note that the default allowed languages for Italian, Dutch, Portuguese and Russian has been removed and Danish has been added in the coolwsd.xml definitions:
<allowed_languages desc=“List of supported languages of Writing Aids (spell checker, grammar checker, thesaurus, hyphenation) on this instance. Allowing too many has negative effect on startup performance.” default=“de_DE en_GB en_US es_ES fr_FR it nl pt_BR pt_PT ru”>da_DK de_DE en_GB en_US es_ES fr_FR</allowed_languages>
When you open a document in Danish it all looks right. The UI is in Danish and the language setting for the document indicated on the bottom line says Dansk which means Danish in Danish. But the spelling control for Danish is not active as you can see from the last word in paragraph 1 which is not a valid word in Danish or any other language as far as I know.
Here I am hammered by a restriction that says “New users are only allowed to add 1 screenshot to a report” or something.
Ok here is a link to the full report.
