HOW TO USE THE SOUNDEX FUNCTION IN GOOGLE SHEETS WITH FLOOKUP
Introduction
Have you ever needed to match names that are spelled differently but sound the same? For example, "John" and "Jon", or "Smith" and "Smyth". This is a common problem in data cleaning, and it's where phonetic matching comes in. One of the most well-known algorithms for phonetic matching is Soundex.
What is the Soundex Algorithm?
Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling. The algorithm mainly encodes consonants; vowels are discarded unless they are the first letter.
Why Use Soundex in Google Sheets?
Imagine you have a customer list with thousands of names. It's likely that there are many variations in spelling for the same person's name. For example, you might have "John Smith", "Jon Smith", and "John Smyth". A simple search for "John Smith" would miss the other two variations. This is where Soundex can be a lifesaver. By matching names based on their sound, you can identify and group these variations together.
How to Use Soundex in Google Sheets with Flookup
Unfortunately, Google Sheets does not have a built-in Soundex function. However, you can easily perform phonetic matching with the Flookup Data Wrangler add-on. Flookup uses a more advanced phonetic matching algorithm than the traditional Soundex, which provides even better results.
Here's how to do it:
- Install the Flookup Data Wrangler add-on from the Google Workspace Marketplace.
- Open your Google Sheet and go to Extensions > Flookup Data Wrangler > Transformation functions > Fuzzy match data > By sound.
- Follow the instructions in the sidebar to select your data, choose your options, and find sound-alike matches.
Flookup's Phonetic Matching vs. Traditional Soundex
While Soundex is a well-known algorithm, it has some limitations. It was originally designed for English names and may not work well for names from other languages. Flookup's phonetic matching algorithm is more modern and sophisticated, providing better accuracy across a wider range of names and languages.
Final Thoughts
Phonetic matching is a powerful technique for cleaning and standardizing your data. While Google Sheets doesn't have a native Soundex function, Flookup provides an easy-to-use and powerful solution for finding sound-alike matches.
