You probably want jsonlines. Being able to open a file in append mode without needing to parse the whole thing is great.

I get why one wants strict parsing rules but i don't see the point of closing tags. It seems nice enough to have [say] logs in json. Why would one need to add closing tags before consuming the json elsewhere? Parsing the entire thing is a huge waste of time if it is large.

I can use csv or html ofc.
