Streaming one JSON object after another having a JSON array in one huge line in the file

I have a problem with huge JSON file (1GB) which contains an array of JSON objects but all of them are in one line. So it looks like...

[{JsonObject1},{JsonObject1},{JsonObject1},...,{JsonObject999999}]

I'm not able to save the content into the memory so I wanted to do this using streaming. I know how to stream line by line but if I have everything in one line only how can I stream JSON object one after another from this one line array? I tried to browse the internet but I couldn't find anything :(
