People Column: Automatically link names to G-Suite account

When I paste a column with a list of names (formatted: firstName lastName), I have to manually connect them to their G-Suite account by searching for their name and selecting their respective profile. This isn’t an issue with a few names but if i’m trying to construct a directory of sorts, I’m expecting this process to be fairly time consuming.

Is there a faster way to connect plain text names to their G-Suite accounts?
