json_xs(1) - Linux man page

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; 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 :)
-t toformat: Write the file in the given format to STDOUT .
"fromformat" 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

Examples

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 :)
