NAME

       json_xs - JSON::XS commandline utility

SYNOPSIS

          json_xs [-v] [-f inputformat] [-t outputformat]

DESCRIPTION

       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".

OPTIONS

       -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
           cbor - CBOR (RFC 7049, CBOR::XS), a kind of binary JSON
           storable - a Storable frozen value
           storable-file - a Storable file (Storable has two incompatible formats)
           bencode - use Convert::Bencode, if available (used by torrent files, among others)
           clzf - Compress::LZF format (requires that module to be installed)
           eval - evaluate the given code as (non-utf-8) Perl, basically the reverse of "-t dump"
           yaml - YAML format (requires that module to be installed)
           string - do not attempt to decode the file data
           none - nothing is read, creates an "undef" scalar - mainly useful with "-e"
       -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
           cbor - CBOR (RFC 7049, CBOR::XS), a kind of binary JSON
           cbor-packed - CBOR using extensions to make it smaller
           storable - a Storable frozen value in network format
           storable-file - a Storable file in network format (Storable has two incompatible
           formats)
           bencode - use Convert::Bencode, if available (used by torrent files, among others)
           clzf - Compress::LZF format
           yaml - YAML::XS format
           dump - Data::Dump
           dumper - Data::Dumper
           string - writes the data out as if it were a string
           none - nothing gets written, mainly useful together with "-e"
               Note that Data::Dumper doesn't handle self-referential data structures correctly -
               use "dump" instead.

       -e code
           Evaluate perl code after reading the data and before writing it out again - can be
           used to filter, create or extract data. The data that has been written is in $_, and
           whatever is in there is written out afterwards.

EXAMPLES

          json_xs -t none <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 :)

          json_xs -f none -e '$_ = [1, 2, 3]'

       Dump the perl array as UTF-8 encoded JSON text.

          <torrentfile json_xs -f bencode -e '$_ = join "\n", map @$_, @{$_->{"announce-list"}}' -t string

       Print the tracker list inside a torrent file.

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