Tool Introduction

This tool parses PHP serialized strings—the format produced by serialize() in PHP—and converts them to readable JSON in your browser. Paste the serialized output from a session, cache or database and inspect the structure instantly.

Supports integers, floats, booleans, null, strings, indexed and associative arrays, and class objects. No data leaves your machine.
