{{For|the json2ttb tutorial|Json2ttb/Tutorial}}
'''json2ttb''' is a external tool for [[About|Railway Operation Simulator]] which allows the user to speed up the creation of complex [[TTB file|timetables]].
The program works by parsing a user-written json file, which is then converted to a [[TTB file]] which can be used in within ROS. The structure of the json file is in such a way that you define a service template, which can then be iterated upon and copied over several instances, which can have non-iterative references, descriptions, times and train data.
===Key Features===
*Allows for unusual repeats of services.
*Create templates of service data and use them for several services.
*Change the reference and description of single repeats.
*Allows for creating [[shuttles]] without using shuttle syntax.
*In most cases, quicker than writing timetables in ROS.
'''What json2ttb cannot do... (yet)'''
*Does not simplify writing individual services.
*No current support for the ROS repeats (e.g. R;30;2;2), repeats are done in a different way.
===JSON Example===
Below is a small excerpt of the json file which can be parsed by json2ttb. This example is taken from the timetable for [[Sheffield East]].
