jp
is a command line tool that reformats JSON to make it easier to read:
$ cat names.json
{"names":["Alice","Bob"]}
$ jp names.json
{
"names": [
"Alice",
"Bob"
]
}
It only adds and removes whitespace, which means that your data won’t get
silently altered. For example, "\u2603"
won’t get converted to "☃"
, and
1.1e1
won’t turn into 11
. The ordering remains the same, and invalid JSON
can be reformatted (within reason). This stuff shouldn’t matter, but people make
mistakes even with a well defined format like JSON, and accurate tools are
important when you’re trying to work out what’s gone wrong.
