NAME ^

Catmandu::Importer::JSON - Package that imports JSON data

SYNOPSIS ^

    # From the command line
    
    $ catmandu convert JSON to YAML < data.json

    # or for faster newline delimited input

    $ catmandu convert JSON --line_delimited 1 to YAML < data.json

    # In a Perl script

    use Catmandu;

    my $importer = Catmandu->importer('JSON', file => "/foo/bar.json");

    my $n = $importer->each(sub {
        my $hashref = $_[0];
        # ...
    });

DESCRIPTION ^

This package imports JSON data. The parser is quite liberal in the input it accepts. You can use the line_delimited option to parse "newline delimited JSON" faster:

    { "recordno": 1, "name": "Alpha" }
    { "recordno": 2, "name": "Beta" }
    { "recordno": 3, "name": "Gamma" }

CONFIGURATION ^

file

Read input from a local file given by its path. Alternatively a scalar reference can be passed to read from a string.

fh

Read input from an IO::Handle. If not specified, Catmandu::Util::io is used to create the input stream from the file argument or by using STDIN.

encoding

Binmode of the input stream fh. Set to :utf8 by default.

fix

An ARRAY of one or more fixes or file scripts to be applied to imported items.

line_delimited

Read line-delimited JSON with a faster, non-incremental parser.

METHODS ^

Every Catmandu::Importer is a Catmandu::Iterable all its methods are inherited. The methods are not idempotent: JSON streams can only be read once.
