This disclosure concerns a barcode reading system that includes a barcode reader and a data manipulation module. The barcode reader reads a barcode, decodes the barcode, and generates decoded data. The data manipulation module includes a data validation module and a data formatting module. The data validation module can perform one or more data validation operations on the decoded data. The data formatting module is separate from the data validation module. The data formatting module can perform one or more data formatting operations on either an output of the data validation module or on the decoded data. The output of the data validation module may include one or more data validation modifications. The barcode reading system may also include a host computer that is in electronic communication with the barcode reader. In some configurations, the barcode reader may include the data manipulation module. In other configurations, the host computer may include the data manipulation.
