Can Bardeen to go through row by row and take an action on an Airtable/Google table?

Yes, you can do this using Bardeen. First, get the table from Airtable/Google by using the command called "get rows of a table." This lets you access each row of your table. Next, if you need to add any extra details to your data, you can use the "merge text" command. This is helpful for combining or adding new information. Lastly, once you've got your data ready, you can put it back into Airtable. For this, use the "update" command if you're changing existing rows, or "add rows" if you're putting in new data.
