Informative post. I just got my introduction to jsonl, the format some of the NIH tools return data. I realize that this is mostly machine readable, but I find formatting helpful. The following was legal in the website you provided:

[
{ "records":
[ { "Name" : "Alfred"
, "Sex" : "M"
, "Age" : 14
}
, { "Name" : "John"
, "Sex" : "M"
, "Age" : 12
}
]
}
]

I find it curious that many programmers put the comma at the end of a line, where one has to find it with more effort and cannot be sure that it was not supposed to be part of the value instead of a delimiter (metacharacter), instead of the front. I find aligning it to the parenthesis or bracket helpful, too. I write my macro parameters in this fashion.

Kind regards,

Kevin
