Parsing tab delimited file with numbers in Javascript

gistfile1.js

callback = function (body, next) {
      var b = body;
      var res = b.split("\r\n");
      var line1 = res[0].split("\t");
      var collection = [];
      for(var i=1;i<res.length;i++){
        var local = res[i].split("\t");
        var object = new Object();
        for(var i2=0;i2<line1.length;i2++){
          var test = local[i2];
          if(! (typeof test === 'undefined')){
            test = test.trim();
          };
          var parsed = parseFloat(test);
          if(!isNaN(parsed)){
            object[line1[i2]]=parsed;
          }
          object[line1[i2]]=test;
        }
        miao.putKeyValue({
          collection: 'SoldHouse',
          key: uuid.v4(),
          data: object
        },callback);
        collection.push(object);
      }
      this.req.collection = collection;
      return next();
}

Not sure that is the problem it works fine as is but doesn't make the number into a float it stays a string.

nm I see now
