generate .json files using .txt files and some REGEX expression

I do have a text file ("all teams all [login to view URL]") with blocks of translations seperated by "||||". A block looks like: "Germany: Afgahnistan, england, ... ,refugee team" - for each of these blocks there need to be a folder generated with the name before the ":" in lower case (so "germany" for example above). - in each of this folder need to be a file named "[login to view URL]" file - this [login to view URL] file looks like the one attached here but with appropiate translations - the order of the teams ("|||| <team1> |||| <team2>") is the same order as the elements in the attached [login to view URL] sample file Also in each folder is a "[login to view URL]" file (I will send template) and in this file there are 11 strings to be translated using [login to view URL] One approach of a rgex template that can be applied to all blocks could be this: [login to view URL]
