# URL\$1PARAMS
<a name="recipe-actions.URL_PARAMS"></a>

Extracts query parameters from a URL string, formats them as a JSON object, and returns the result in a new column.

For example, consider the following URL.

```
https://example.com/?firstParam=answer&secondParam=42
```

If you use this value as an input to `URL_PARAMS`, the output value is as follows.

```
{"firstParam": ["answer"], "secondParam": ["42"]}
```

**Parameters**
+ `sourceColumn` – The name of an existing column.
+ `value` – A character string to evaluate.
+ `targetColumn` – The name of the new column to be created.

You can specify either `sourceColumn` or `value`, but not both.

**Example**  
  

```
{
    "RecipeAction": {
        "Operation": "URL_PARAMS",
        "Parameters": {
            "sourceColumn": "my_url",
            "targetColumn": "URL_PARAMS Column 1"
        }
    }
}
```
