Field values such as payee names from downloaded transaction records are automatically renamed when appropriate, to make them consistent with corrected field values, such as actual payee names. If a downloaded field value corresponds to an alias for an corrected field value, the downloaded value is re-placed with the corrected field value. If a renaming rule applies to a downloaded field value, the downloaded field value is replaced according to the renaming rule. The invention automatically generates aliases and/or renaming rules when appropriate.
