Hi Pranav
When you load you first language plugin you get access to the Languages subtree in System Localisation. You'll see:
Translated Name/Fields
Messages
Field Labels
Choices
Translated Text
You also get the debug options for I18N under the system diagnostics areas.
This is the very start of your translation journey
You'll get ServiceNow's translated items and when you change your language you'll see their suggested translations.
There is a lot in each pack so it can take a while to load. Just be patient etc.
Stuff that is not immediately obvious is that there are plenty of scripts, rules etc in SN that output messages. These are not always translated, you may have to create messages for them and use getMessage to call them in order to translate. Newer instances are better at this but if yours is an upgraded older one you may have some work on.
Also the translation of records is not dynamic. (Labels and choices etc are)
So if you select a language of spanish and type some words into a notes or text field and save the record it will not be translated into english if you change your language to english. This also applies to the system messages.
good luck
