it would be great if someone could help me with this. I want to analyze Twitter archives that users can download for themselves. I get a ZIP file from Twitter with a lot of .js data - that's where the problem starts. What I have found out so far: If I manually remove the header of the js ("window.YTD.direct_messages.part0 ="), then I can open it as JSON with RJSONIO - but I don't want to have to do that manually everywhere. Does anyone know a way to open the JS file or how I can accomplish the above steps (delete the row and open as json) in R?

That is how the js header looks like - BTW: it seems to be important not to delete the square brackets as well if you want to save it as json:
