## Free Online Unserializer - Parse Serialized Data Instantly

Paste a serialized string and instantly convert it into a human-readable format. Choose between `print_r()` for a quick overview or `var_dump()` for type-annotated detail. Ideal for inspecting WordPress options, transients, and metadata stored in the database.

## How to Use the Unserializer

Paste a serialized string into the input box. You can grab these from database fields, API responses, or debug logs.
- **Step 2:**

Select an output format — `print_r()` for a compact view or `var_dump()` for detailed type and length information.
- **Step 3:**

Copy the formatted output and use it in your debugging workflow.

## FAQs

- **What is a serialized string?**

Serialization converts a data structure into a compact string representation for storage or transfer. This tool reverses that process so you can read the original data.
- **Where do I find serialized data?**

Common sources include the WordPress wp_options table, user meta fields, WooCommerce order meta, transient caches, and plugin settings stored in the database.
- **What is the difference between print_r() and var_dump()?**

print_r() shows values and structure in a concise format. var_dump() adds explicit type and length annotations for every value, which is more useful for type-sensitive debugging.
- **Does this tool modify the original data?**

No. The tool only reads and formats the input — nothing is stored, sent, or altered.
