Guides

Convert PHP's serialize() output back into readable, indented JSON — useful for inspecting serialized values pulled from a database column, a WordPress wp_options row, or a cache file, without spinning up PHP.

How to use it

  1. Paste a serialized PHP string into the input box, or upload a .txt file containing one.
  2. The deserialized value is shown as formatted JSON on the right, updating as you type.
  3. Copy or download the result.

What gets parsed

All of PHP's native serialized types: arrays (a:), objects (O:), strings (s:), integers (i:), floats (d:), booleans (b:), and null (N;).

  • A PHP array with sequential integer keys starting at 0 becomes a JSON array; any other array (string keys, or gaps) becomes a JSON object.
  • A PHP object becomes a JSON object with __className and __isObject: true alongside its properties, since JSON has no native concept of a class name.
  • A serialized string nested inside another serialized value (a value that was itself serialize()d before being stored) is unwrapped recursively.

What if the data is invalid?

If the input isn't well-formed PHP serialization, the tool returns your original input unchanged rather than throwing an error.

Privacy

Everything runs entirely in your browser. Your data is never uploaded to a server.
