# Timeseries

### Overview

The **Timeseries** button lets you export process variable readings from TilliT into Excel. You select an asset, a process variable, and a time range — the data is then loaded into a new Excel sheet.

For data to be available, Process Variables must first be configured in TilliT and must be actively capturing data.

### Opening Timeseries

In the **TilliT V2** ribbon tab, click the **Timeseries** button.

The task pane will open showing the Timeseries view. Click **Add** (or the **+** button in the header) to start loading data.

### Loading Timeseries Data

#### Step 1: Select Asset

Select the asset whose process variable data you want to export. All active assets in your TilliT configuration are listed.

#### Step 2: Select Process Variable

Select the process variable you want to export from the list of variables configured for the selected asset.

#### Step 3: Time Selection

Choose how to define the time range for the export:

* **Today** — all data from the current day
* **Yesterday** — all data from the previous day
* **Pick a date** — all data from a single specified day
* **Pick a start and end time** — data within a specific time window (within 24 hours)

**If you choose "Pick a date":**

A date picker appears. Select your date, then click **Next**.

**If you choose "Pick a start and end time":**

Two date-time pickers appear — one for the start and one for the end. The window cannot span more than 24 hours. If the selection is invalid, an error message will appear. Click **Next** when ready.

#### Step 4: Configure & Load

Before loading, you can optionally customise the **Sheet name** — this is the name of the Excel sheet the data will be placed in. By default it uses the process variable name.

Click **Load Data** to export the readings into Excel.

### Viewing the Data

The timeseries data is loaded into a new sheet. The sheet contains columns for the timestamp and reading value, and is named after the process variable (or the custom sheet name you provided).

The task pane will show a card for the loaded timeseries source.
