What Is JSON to Perl?
Perl uses JSON or Cpanel::JSON::XS for encoding and decoding. This tool generates Perl data structures (hashes and arrays) from your JSON. The JSON spec defines the format; conversion runs in your browser. Nothing is sent to a server.
How to Use This Tool
Paste or Upload JSON
Paste your JSON or upload a file. Set the package name in the config panel if you want a module wrapper. Invalid JSON will show an error. Use the JSON Validator to check syntax first.
Review the Perl Output
The right panel shows generated Perl code. Use decode_json or from_json from the JSON module to parse JSON at runtime. The generated structures are useful as templates or static config.
Copy or Download
Use Copy or Download. For formatting JSON first, use the JSON Formatter. For validation, use the JSON Validator.
JSON to Perl Examples
Here is an example of generating Perl data structures from a JSON object.

When JSON to Perl Helps
When writing Perl scripts, CGI tools, or legacy systems that consume REST APIs or config files, you need data structures for the JSON. Pasting a sample here gives you Perl hashes and arrays you can use with decode_json or from_json. The generated code is useful for static config or as a template. For dynamic parsing, use the JSON module. For pulling out specific values, use the JSON Path tool.
Frequently Asked Questions
Perl hash vs JSON object?
JSON objects map to Perl hashes (%hash or $hashref). JSON arrays map to Perl arrays (@array or $arrayref). Use the JSON module to convert between them at runtime.
JSON vs Cpanel::JSON::XS?
The JSON module is pure Perl. Cpanel::JSON::XS is faster (C-based). Both produce the same data structures. Use Cpanel::JSON::XS for performance-critical code.
Is my data private?
Yes. Generation runs entirely in your browser. No JSON or code is sent to any server.
Can I use with Mojolicious?
Yes. Mojolicious has built-in JSON support. The generated structures work with Mojolicious::Request and response handling. Use decode_json for API responses.
References vs direct structures?
Perl typically uses references for nested structures. The generator produces $hashref and $arrayref syntax. Access with $ref->{key} or $ref->[0].
