Fuzzy Lookup in Excel giving very low similarity

Occasional Visitor

Hello. Today I've tried the Fuzzy Lookup addin both in Excel 2016 and Excel 365, and in both cases, very similar strings get a very low similarity (0.001) and with a slightly smaller change they don't get matched at all.

Steps to reproduce:

  1. Open the example file from the addin folder (Portfolio.xlsx)
  2. Click the Fuzzy Lookup icon to open the dialog
  3. Select the Portfolio and SP500_data tables
  4. Choose "Company" in both left and right tables
  5. Leave all defaults and click Go to create the comparison table

Expected result: different similarity values as high as 90% (as seen in this article, with the same data).

Result I get: all matches have 0.001 similarity.


Exactly the same has happened with other data I have written as tests. I haven't found any parameter that lets me get different results.

Do you have any idea why this could be happening? Thanks!
