How duplicates are detected

BankFileFix compares transactions by date, amount and description to surface likely duplicates. It never deletes anything automatically — you decide what to remove.

Works across merged files

Drop several bank exports together and BankFileFix flags duplicates that appear across files, not just within one. Overlapping statement periods are highlighted too.
