Presumably your string has numbers in string format. Use ToExpression to
convert numbers in string format to numbers.

In[1]:=
aString = {"2", "4", "5.5"};

In[2]:=
Head /@ aString
Out[2]=
{String, String, String}

In[3]:=
ToExpression[aString]
Out[3]=
{2, 4, 5.5}

In[4]:=
Head /@ %
Out[4]=
{Integer, Integer, Real}
