Sajeev, the most important and cheapest tool to use is called “BRAIN”. BRAIN is able to convert any language into any other language, after a small learning curve of some years.
It’s a pity that many people do not use BRAIN though they have it available and it is for free.
BRAIN must not be istalled on the system, it is automatically there, most time it resides in a bowl in front of the screen. BRAIN works together with FINGER, another free tool with 10 occurences. FINGER is used to input data to the system using KEYBOARD (sorry, not for free, but mostly available).
Hope that helps
