Multiple text files with fileAsync

Pretty new to Airtable and Javascript
I’m trying out Airtable to see if I can organize my organizations data better.

When importing new data to our database I would like to read from many text files, collect the data from the files (which unfortunately isn’t organized too great), and insert the data into tables.

Is there a way to queue multiple text files to read with fileAsync? There are hundreds of files, so doing one at a time is not useful.
