A computer-implemented method related to a data mapping and import system is disclosed. A source file including a plurality of data records may be received, each data record comprising a sequence of data segments associated with source data. A target data structure comprising a plurality of target fields to which to import the source data of the source file may be identified. A mapping format comprising associations between each of the data segments for the plurality of data records and a target field of the plurality of target fields. And the source data from each of the data segments of each of the plurality of data records may be imported into the target field associated with each data segment based on the mapping format.
