FinCleaner is a simple tool to prepare transactions exported from your bank account for analyzation or import into another tool like Firefly III.
It features a simple rule engine to parse, filter and modify CSV files. It is possible to modify fields and remove transactions.
Furthermore, FinCleaner generates warnings for duplicate transactions, e.g. for transfers between several accounts.
Create a configuration file appropriate for your bank exports. A single configuration file may contain multiple parser definitions and rule sets, which are chosen automatically based on file names.
Then invoke FinCleaner with the configuration file and your exported CSV files, e.g. by drag & dropping all files onto the application.
