1. Log in to your ARM account.
2. Hover your mouse over the **`DataLoader`** module and choose the **`DataLoader`** option.
3. Click **`Delete`** on the right side of the screen.

4. Choose your [**`Salesforce Org`**](broken://pages/9pLgfInGvztETx4cXCc2) and select your org environment (**`Production or Development Edition`**, **`Sandbox`**, or **`Pre-Release`**).
5. The corresponding **`URL`** and **`Username`** are auto-generated based on the selection.
6. Click **`Login and Fetch Objects`** to load all objects from your Salesforce Org.

    * **All** – Displays all fields.
    * **Mapped** – Only mapped fields.
    * **Unmapped** – Only unmapped fields.
15. Ensure all required fields are mapped, then click **`Next`**.
16. On the **`Process Summary`** screen:

| **Use UTF-8**  | Use UTF-8 encoding unless data contains non-English alphabets.                   |

22. Click **`Run`**.
