@jhi - I wrote a script for fuzzy matching using the Levenshtein distance algorithm. You can find it on the official Airtable community here:
About half way down the thread you’ll see the JS version of this that can be incorporated into an Airtable script. I’ve tried using this in an Airtable automation, but, generally, it does not work. Not because it won’t work technically, but, if you have a large number of records to compare the automation will run out of time (30 seconds is the maximum execution time for a single script)
