This macro is like the Fuzzy match tool and calculates a similarity match ratio using Python difflib's SequenceMatcher function. The difflib can calculate the similarity ratio by the Gestalt Pattern Matching algorithm. This macro outputs the S input data with the result of calculating the similarity ratio between the specified field of the S input and the specified field of the T input.
This macro has two options. One is that can output only the records with the highest similarity ratio. Another option is that output the records more than a threshold of similarity ratio that you set.
