FLOOKUP

Fuzzy Matching and Lookup Functions for Google Sheets

ABOUT FLOOKUP

Flookup is an advanced tool for performing fuzzy match and fuzzy lookup tasks in Google Sheets. With Flookup you can:

  • Find and match typos.
  • Highlight duplicates.
  • Remove duplicates.
  • Calculate the percentage similarity between strings.
  • Extract unique values from any column.

Flookup is also the perfect replacement for VLOOKUP and INDEX/MATCH because it's not affected by factors like the sort order of columns or rows, the presence of punctuation marks or the letter case of the strings.

TEN REASONS WHY YOU SHOULD CHOOSE FLOOKUP

  • It has familiar, intuitive and easy-to-use functions.
  • It is robust. Flookup is powered by a battle-tested algorithm with millions of rows and columns of data under its belt.
  • It is completely flexible. You can search any column with FLOOKUP and search any row with HFLOOKUP, not just the leftmost column or topmost row.
  • It is fast. Flookup runs on one of the fastest fuzzy matching algorithms in the world and all its functions are optimised to complete tasks in the shortest time possible.
  • It is dynamic. If the first match does not suit your needs, you can instruct Flookup to return the next best match until all possible matches have been exhausted.
  • It has range. You can combine any number of strings as the lookupValue, giving you options to increase the specificity of your query.
  • It offers value for money. Flookup is free forever and, should you need more functionality after testing it, you can easily subscribe for a better experience at a very friendly fee.
  • It speaks your language. Flookup is not limited to English; it can process text in most international languages.
  • It is secure. Flookup does not expose, store or share any of the spreadsheet data it processes, meaning that your data remains safe and private.
  • It is on the G Suite platform. Working out of the G Suite platform is full of benefits for individuals and organisations alike. Using Flookup taps directly into those benefits.

POPULAR FUZZY MATCHING ALGORITHMS

Fuzzy matching (also called 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, word or phrase comparisons, regular expressions and edit distance. Examples 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.
  • The Brain: "Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteers be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe."

Flookup uses modified versions of n-gram and refined Soundex to analyse strings, depending on the function being used.
