The document management system has a Native Template database including a list of templates for one or more types of documents having common characteristics and a Conversion Database including a list of one or more data points associated with each listed document type, one or more descriptive text entries associated with each listed data point, and proximity range information relating to the location of the data point within the descriptive text. The locations of words, sentences, paragraphs, and sections within the externally generated document are recorded and a document type is selected from the Native Template database that has common characteristics. A data point is selected from the template and the introduced document is searched for Possible Data Points. A determination is made as to whether Possible Data Point values are located within a Proximity Range. A cumulative Evaluation Score is calculated for each Possible Data Point value. The Possible Data Point with the highest score is recorded. These steps are repeated until each data point has been selected.
