can I also upload a questionnaire in English or German

Yes, the language of the questionnaire is not a barrier

The system recognizes questionnaires in English and German just as well as in Dutch. For a recurring format — a portal of a bank, a major customer or a sector questionnaire — the question is recognized based on content, not on the exact wording in one language. "What is the registered office address of the company?" and "Wat is het vestigingsadres van de onderneming?" point to the same answer in the chain file: the establishment address of the company. The same applies to a question about "number of employees" or "Anzahl der Mitarbeiter" — that comes from the same field as the number of employees.

The answer that is suggested comes in the language recorded in the chain file — usually Dutch, unless a field is specifically filled in in another language. For a new format that the system does not yet recognize, the recognition of individual questions may be less complete than for a familiar Dutch portal; in that case, you can see for each question whether a suggestion has been made or not. Nothing is automatically submitted: each suggested answer is only used after confirmation with yes or no, regardless of the language of the original question.

Recognition works on question content, not on source language

This follows from how the chain file is structured: the underlying data — for example, data from the Trade Register Act 2007, or an answer based on the EFRAG VSME baseline module — are separate from the language of a specific questionnaire. An English or German question is linked to the same underlying data as the Dutch variant; the source of the answer does not change with the language of the question. This makes recognition across languages possible, without requiring a separate translation step or separate review per language.
