Serialized data is unreadable

[bendoh]

Serialized data (PHP or JSON) could be presented in a structured format (there may be JavaScript libraries that will create a navigable structure of serialized data... But a quick Google search came up with little.)

I would say for serialized meta data values, present a link instead that shows the serialization format, i.e.

"JSON-Serialized Data"

or

"PHP-Serialized Data"

Which could show a popup for navigating the serialized data.

What about unserializing it and var_exporting it as an array?
