Norwegian translation

Hello,

I just completed (100%) the Norwegian translation of Zoho Sheet. I notice that most of the other products have not been translated, or not completed.
For the translation of Zoho Sheet into Norwegian I used the very good module found here: https://translate.sheet.zoho.com/l10n.do

1. How can I translate other Zoho programmes (such as Mail, Writer etc.) with a similar tool?

2. As a Zoho Business user, is it possible to use the Norwegian version in Sheet, whilst using English for the other programmes which are not yet translated (since I notice that I do not benefit from this translation as a Business user)?

Best regards,
Erik
