At　present,　there　are　a　large　number　of　data　stored　in　spreadsheets.　With　the　development　of　semantic　web　and　ontology　technology,　importing　the　spreadsheet　data　into　semantic　web　is　helpful　for　knowledge　sharing　and　acquisition.　Existing　conversion　methods　always　convert　the　spreadsheet　data　into　RDF,　which　cannot　be　integrated　into　constructed　ontology　base.　This　paper　proposed　an　open　architecture　called　Anyt2OWL　for　the　conversion　from　various　traditional　formats　to　OWL　based　on　ontology　schema.　Following　Any2OWL,　the　method　of　converting　spreadsheet　to　OWL　which　can　be　imported　into　ontology　base　is　implemented.　In　addition,　a　declarative　language　is　designed　to　express　the　mappings　between　spreadsheet　and　ontology.　©　2012　IEEE.
