The process of transferring data from a spreadsheet into a database is known as 'importing.' Importing frequently involves translating data from one format to another and inserting it into the database system where it can be managed more effectively. 'Inputting' often refers to manually entering data into a system, which is not the case here. While 'embedding' could sound plausible, it refers to inserting objects like images or videos into a document rather than transferring bulk data. 'Transposing' specifically means switching the rows to columns or vice versa, not moving data from one system to another.
