John, Here is one way. let us suppose the data is in a file that we import into Mathematica data = Import["/Users/brian/Desktop/data.text", "CSV"] Here is what the data looks like data//FullForm FullForm=List[List["<2.54 3.11 2.89> "],List["<3.58 5.24 5.66> "]] Now we make use of StringToStream to create an input stream for each String, and then use ReadList to read in each data point which is then transformed into an expression Map[ToExpression[ReadList[StringToStream[First[#]], Word,WordSeparators->{"<"," ",">"}]]&,data]//FullForm List[List[2.54`,3.11`,2.89`],List[3.58`,5.24`,5.66`]] Cheers, Brian
