Something like the following sequence might work for you. idata = Import["Test.txt", "Table"]; (* import all the data as strings -- the default for *.txt *) sdata = Select[idata, UnsameQ[#[[1]], "#"] &] (* drop all header lines -- sdata = Drop[idata, {1, 12}] can also work *) ddata = StringReplace[#, {"," -> "."}] & /@ sdata (* replace our commas with decimal points *) ddata = Map[ToExpression, ddata] (* ... and convert everything to expressions -- reals *) Regards, Dave.
