# Navigating the Add-in

### Overview

The TilliT Excel Add-in V2 uses a single task pane that opens on the right side of Excel. All five features share this same pane — you switch between them using the dedicated buttons in the **TilliT V2** ribbon tab.

### Logging In

When you first open the add-in, you will see the login screen. Click **Log In** to authenticate with your TilliT account.

After logging in, the pane will display your active tenant name in the header.

### The Ribbon Tab

The **TilliT V2** tab appears in the Excel ribbon after installation. It contains five buttons, each opening a different view inside the task pane:

| Button          | Opens                                                                      |
| --------------- | -------------------------------------------------------------------------- |
| **Data**        | Entity Data Source — load or manage TilliT configuration and instance data |
| **Timeseries**  | Timeseries — export process variable readings                              |
| **Orders**      | Orders — load or upload TilliT and Scheduler orders                        |
| **Boards**      | Boards — load board items or edit board definitions                        |
| **Translation** | Translations — export translatable entity data                             |

### The Header Menu

Once logged in, the header shows your **tenant name** and a menu button to the right. Clicking this button gives you access to:

* **Switch Theme** — toggle between light and dark mode
* **Language** — change the add-in display language
* **Logout** — sign out of the add-in
* **Return to Classic** — switch back to the original Excel Add-in (V1)

### Returning to the Classic Add-in

If you need to use the original add-in, click **Return to Classic** from the header menu. This does not uninstall V2 — it simply opens the classic (V1) add-in in the same pane.
