I assume your real question is how to convert numbers formatted
as strings to numbers you can manipulate as numbers in
Mathematica. The answer is to use ToExpression. That is
ToExpession["2"]
will output the integer 2 that can be used in subsequent operations.
If there are quotes embedded in the string you need to convert
to numbers, these can be removed using StringReplace. Specifically,
StringReplace[string, "\""->""]
will remove any embedded quote characters. But the result of
this StringRepplace is still a string, not a number you can add,
subtract etc from other numbers.
