Systems, methods and tools for mapping data elements between a source data structure and a target data structure without the needing exactly matching values or a dictionary of synonyms. The embodiments of the present disclosure auto map data elements having similar phonetic sounds, even in the presence of one or more misspellings or alternative spellings. Embodiments of the present disclosure utilize Soundex algorithms to generate a key corresponding to each source and target data elements. Each Soundex key may be generated based on the phonetical sounds of the source and target data elements. By using phonetical sounds to generate the key, a Soundex algorithm allows for similarly sounding words, alternatively spelled words or misspelled words to generate the same Soundex key, creating equivalence between the naming of source and target data elements once the auto mapping function is implemented.
