FUZZY MATCHING AND LOOKUP FUNCTIONS FOR GOOGLE SHEETS

YOUR DATA QUALITY PROBLEM

If you deal with merging multiple sources of data, data migration, importing data into your CRM, etc. then you have undoubtedly had data quality issues in your work. According to this infographic by IBM, poor data quality costs the United States economy about $3.1 trillion every year. This easily translates to no less than $100 per record, on average.

Data quality issues might arise when two sources of data, that have similar records, are merged. This creates duplicate records that lead to lower productivity, expensive budgets, low customer satisfaction and inefficiency. These factors consequently affect marketing, finance and general business operations negatively.

You might also face data quality issues when comparing or extracting information from different sources. This task is made harder if your data set contains typos, spelling variations, punctuation marks and the like. Having correct and up-to-date records in your data is critical to the success of your business and Flookup can help you achieve that easily.

In summary, Flookup will help you increase productivity, increase efficiency, reduce your error rate and save money.

    • Remove duplicates.
    • Highlight duplicates.
    • Lookup matches of strings.
    • Calculate the percentage similarity between strings.
    • Find the sum or average of numbers that correspond to partial matches.

POPULAR FUZZY MATCHING ALGORITHMS

Fuzzy string matching (also called partial or approximate string matching) is a technique for comparing strings that might have a less than 100% match. There are different techniques that are applied by fuzzy matching algorithms and the most popular involve the use of wildcard characters (in combination with functions like VLOOKUP or INDEX/MATCH), word or phrase comparisons, regular expressions (RegEx/RegExp) and edit distance. Examples of such implementations include:

    • Levenshtein Distance: This algorithm calculates and returns the minimum number of single-character edits (i.e. insertions, deletions or substitutions) required to change one word into another.
    • Damerau–Levenshtein Distance: This algorithm is exactly like Levenshtein distance with one exception; it includes transpositions amongst its edits.
    • Jaro–Winkler Distance: The Jaro distance between two words is the minimum number of single-character transpositions required to change one word into the other.
    • n-gram: This is a contiguous sequence of n items from a given sequence of text or speech. The items can be phonemes, syllables, letters, words or base pairs according to the application.
    • Soundex: This 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.
