How to convert an bilingual Excel file glossary into a TB

Hello fellow translators,

I have just used some spare time to polish a large bilingual Excel file (A column: source text; B column: target text) glossary and now I would like to convert it into a MultiTerm term base.

Actually, I seem to have done it twice or thrice in the past, but it was long ago, I have forgotten the process and moreover things may have changed from one Studio version to a newer one (I am using Studio 2021). So I will be thankful to whomever can update me.

Best regards.
