documentation and a few books looking for the equivalent of a simple string-to-number function like vba's "Value". Could not find an answer. Thanks .
ToExpression[list] will work.
Or you could implement a stricter version:
Replace[
Characters[list] /. Table[ToString[i] -> i, {i, 0, 9}],
{valid : {__Integer} :> FromDigits[valid], _ -> $Failed},
{1}
]
