I’m helping a nonprofit setup their membership system in Airtable.

We have a Master Membership table with about 400 member records.

Occasionally we get a CSV of member records that have renewed their membership.

What do I do to update the Master Membership table using the renewals table?

I realize this is a big topic, but I’m just looking to understand how to merge an update table with a master table.

Thanks in advance for any guidance!
