## Example

In this example, we will turn a list into a comma-separated string and print the result in the console.

### Step

1. Drag a `button` component to the canvas and open the `Action` tab. Select the `press` event of the button and drag the `Log.write` function to the event flow.
2. Call the function `List.combine` inside the `Log.write` function.
3. Then call the function `Conversion.toList` inside the `data` parameter of the `List.combine` function. Add a "," in the `delimiter` parameter.
4. Enter the values of the list to concatenate into a string in the `Conversion.toList` function.

   ![](/files/Z0iifU89j51cETq3S7Qz)

### Result

1. The console will print the concatenated string of text.
2. In this example, the value printed will be `3,1,5`.
