json_xs − JSON::XS commandline utility
json_xs [−v] [−f inputformat] [−t outputformat]
json_xs converts between some input and output formats (one of them is JSON ).
The default input format is "json" and the default output format is "json−pretty".
|
−v |
Be slightly more verbose. |
−f fromformat
Read a file in the given format from STDIN .
"fromformat"
can be one of:
json − a json text encoded, either utf−8,
utf16−be/le, utf32−be/le
storable − a Storable frozen value
storable-file − a Storable file (Storable has two
incompatible
formats)
clzf − Compress::LZF format (requires that module to
be installed)
yaml − YAML (avoid at all costs,
requires the YAML module :)
eval − evaluate the given code as
(non−utf−8) Perl, basically the
reverse of "−t dump"
−t toformat
Write the file in the given format to STDOUT .
"toformat"
can be one of:
json, json−utf−8 − json, utf−8
encoded
json-pretty − as above, but pretty-printed
json−utf−16le, json−utf−16be −
little endian/big endian utf−16
json−utf−32le, json−utf−32be −
little endian/big endian utf−32
storable − a Storable frozen value in network format
storable-file − a Storable file in network format
(Storable has two
incompatible formats)
clzf − Compress::LZF format
yaml − YAML
dump − Data::Dump
dumper − Data::Dumper
Note that Data::Dumper doesn’t handle self-referential data structures correctly − use "dump" instead.
json_xs −t null <isitreally.json
" JSON Lint" − tries to parse the file isitreally.json as JSON − if it is valid JSON , the command outputs nothing, otherwise it will print an error message and exit with non-zero exit status.
<src.json json_xs >pretty.json
Prettify the JSON file src.json to dst.json.
json_xs −f storable−file <file
Read the serialised Storable file file and print a human-readable JSON version of it to STDOUT .
json_xs −f storable−file −t yaml <file
Same as above, but write YAML instead (not using JSON at all :)

Fetch the cpan-testers result summary "JSON::XS" and pretty-print it.
