It's not that hard to write a little program to convert those numbers to g-code that would produce the same path. However, I see a lot of problems comparing those with the original g-code.
For example, how do you know whether the numbers were the result of a lot of short line segments in the original program or an interpolated circle?
There are many alternate g-codes that can produce the same motion and it will be impossible to guess which one to choose from.
I don't think your problem is solvable for that reason.
