The present invention relates to an electronic catalog data creating and/or displaying apparatus and method. The electronic catalog data creating apparatus comprises a user interface through which a user enters parts data and a data converter which converts data, entered through the user interface, to a predetermined data format. The user interface, in turn, comprises a property data input unit for receiving part property characteristics and its contents and a value range input unit for receiving the range of input or presentation values or presentation conditions of each property entered through the property data input unit. The value range input unit also has a plurality of fields, each of which will accept the following three code descriptions: a code description indicating a value range check condition, a code description indicating a value range to be used when the value range check condition is satisfied, and a code description indicating a value range to be used when the value range check condition is not satisfied. On the other hand, the data converter comprises a condition expression converting unit. The condition expression converting unit searches for a code entered through the value range input unit and converts the value range check condition or the value range to a predetermined data structure description according to a specified content indicated by the code.
