icsv2ledger, maintained by eonseed, includes the following enhancements over the original:
Fuzzy Matching: The most significant improvement is the addition of fuzzy string matching using thefuzz. This makes the tool much more forgiving of variations in transaction descriptions.
Fuzzy Threshold Option: A --fuzzy-threshold option allows you to control the sensitivity of the fuzzy matching algorithm.
Improved Robustness: The code includes better error handling and input validation.
Modern Dependencies: Updated to use thefuzz, a well-maintained fork of fuzzywuzzy.
Clearer README: This updated README provides more detailed information and instructions.
