<figure><img src="/files/DXRdkbfNjxBwvqOX9kYe" alt=""><figcaption></figcaption></figure>

The **Param to Table** task in **Gaio DataOS** allows you to generate a table containing the values of selected [parameters ](broken://spaces/-MPpFa6rq60XeC7QMDh7/pages/-MRfxF3BmSVB6yYzqn4b)available in the current environment. This is useful when you want to use parameter values inside flows, merge them with data sources, or display them dynamically in reports.

{% hint style="warning" %}
This task can only be used when one or more parameters are already defined in the environment (either global, user, or contextual parameters).&#x20;
{% endhint %}

***

## How to Use

### **1. Open the Task**

Go to the menu:\
**Tasks > ETL > Param to table**

***

### **2. Configure the Task**

* **Task label**: (optional) Name for identifying this step in your flow.
* **Result table**: Enter the name of the new table that will store the selected parameters (e.g., `param_table`).

***

### **3. Select Parameters**

* Under the **params** section, all available parameters will be listed.
* Use the checkbox to select the ones you want to include in the resulting table.
* You can filter the list if many parameters are available.

**Example:**\
Select `userId`, `region`, and `product` to create a table with those values as columns.

***

### **4. Save and Use**

* Click **Save** to register the task in your flow.
* The resulting table will contain a **single row**, with each selected parameter as a **column** and the current value of that parameter as the cell content.

***

#### ✅ Use Cases

* Join parameter values with external or internal tables
* Use parameter values as inputs to other ETL steps
* Display user-specific or dynamic filters in dashboards
* Log or export execution context for audits or tracking
