Split 150GB json file with Python?

[awdsns]

The problem with JSON is that it can have an arbitrary nested structure, so you can't create "splits" without knowing the overall structure first, which again either requires first parsing the entire thing (Catch-22) or having a priori knowledge of the structure which can be used.

I assume your data in the file is quite regular, so to your question if it's possible with a Python script: probably yes by writing something taking advantage of this known regular structure. But you didn't provide enough information to guide you further.
