How do replace word numbers to digit but I don't have an idea

Question

"one" : 1,
"two": 2,
"hundred"

If I try two hundred
Return 200

Answer 1

Maybe it works,
...
"one hundred" : 100,
"two hundred" : 200,
...

Answer 2

That seems like a tough question, you'll probably need to define a dictionary for every possible word which is very tedious, I wonder if there's an efficient way to this
