How to Publish Extract to Tableau Server

Creating an insightful Tableau dashboard is only half the battle, the real value comes when you share it with your team. To do that effectively, you need a reliable, up-to-date data source powering your visuals. This is where publishing a Tableau Extract to your server becomes a game-changer. This article will walk you through exactly what an extract is, why you should publish it separately, and the step-by-step process for getting it done right.

First, What Is a Tableau Extract?

Before we jump into publishing, let’s clear up what an extract actually is. A Tableau Extract (with file extensions like .tde or, more commonly now, .hyper) is a saved, compressed snapshot of your data. Instead of querying your live database every time you load a dashboard, Tableau queries this local, optimized file.

Think of it like the difference between streaming a live sports game versus downloading the highlights afterward.

• A Live Connection is like the live stream. It’s connected directly to the source, showing you exactly what’s happening at that moment. This is great for data that changes by the second, but it can put a heavy strain on the source database and can be slow if the connection is poor or the database is under load.
• An Extract is like the downloaded highlights. You get all the important data in a compact, fast-loading format. It’s not “live,” but you can schedule it to refresh automatically to get updated highlights every day, every hour, or whatever cadence you need.

Why Use an Extract Instead of a Live Connection?

Extracts offer several key advantages that make them the preferred choice for most analytics scenarios:

• Better Performance: Querying a local .hyper file is almost always faster than querying a remote database, especially a complex one. Dashboards built on extracts load faster and feel more responsive.
• Reduced Database Load: By using an extract, you’re not repeatedly pinging your main production database every time someone reloads a dashboard. This keeps your database admins happy and your operational systems running smoothly.
• Offline Access & Portability: Since the data is stored within your Tableau workbook file, you can analyze it without an active internet connection to the original data source. This is perfect for when you’re working on the go.
• Data Access Control: You can create and share an extract that only includes a subset of data (for example, only the last year’s sales) without giving users access to the entire historical database.

Why Publish an Extract to Tableau Server? It’s All About "One to Many"

So, you’ve created an extract in Tableau Desktop. Great. Now why should you publish that data source separately to your Tableau Server or Tableau Cloud environment?

Publishing your data source creates a single, governed, and centrally managed asset that multiple workbooks — and multiple people — can connect to. This moves you from a disorganized “one-to-one” model (one workbook, one embedded extract) to an efficient “one-to-many” model (one server extract, many workbooks).

Key Benefits of a Published Data Source

• A Single Source of Truth: When everyone is connected to the same published extract, you eliminate inconsistencies. No more confusion over who has the “latest” version of a sales report, because everyone is building their dashboards from the same foundational data.
• Centralized Refresh Schedules: This is the big one. Instead of you personally having to refresh and re-publish your workbook every morning, you can tell Tableau Server to refresh the extract for you on a set schedule (e.g., every morning at 5:00 AM). This keeps the data fresh for everyone who uses it, automatically.
• Improved Performance at Scale: If ten different dashboards all need the same data, one centrally refreshed extract on the server is far more efficient than ten separate workbooks, each with its own extract trying to refresh.
• Better Security and Governance: Data source credentials (like usernames and passwords for your database) can be embedded and stored encrypted on the server. This means analysts can build reports without ever having the direct database credentials, keeping your data secure.

The Prerequisites: What You Need First

Before you begin the publishing process, make sure you have the following in place to ensure a smooth workflow:

• Access to Tableau Server or Tableau Cloud: You’ll need credentials and, crucially, publishing permissions for a specific project (folder). If you don’t have this, talk to your Tableau administrator.
• A Workbook with an Extract: In your Tableau Desktop workbook, your data source should already be set to “Extract” mode. If it’s currently a “Live” connection, right-click the data source in the Data Pane and select “Extract Data...”.
• Knowledge of Your Project Folder: Know which project on the Tableau Server you intend to publish to. Data sources are often published to a dedicated “Certified Data Sources” or similar project folder.
• Data Source Credentials: For scheduled refreshes to work, the server needs to be able to access the original data source. Know the credentials and decide if you will embed them during the publishing process (this is the most common approach for automated refreshes).

Step-by-Step Guide: Publishing Your First Tableau Extract

Ready to go? Follow these steps carefully to publish your extract as a standalone data source that your whole team can use.

Step 1: Open Your Workbook & Connect to the Server

First, open the Tableau Desktop workbook that contains the data extract you want to publish. Your dashboard can be finished or just a work-in-progress — it doesn’t matter. The main thing is that the data source is configured as an extract.

Next, go to the top menu and click Server > Sign In.... Enter your server’s URL, your username, and your password to establish a connection.

Step 2: Start the Publishing Process for the Data Source

There are two primary ways to share your work: “Publish Workbook” and “Publish Data Source”. For our goal, we want the second one. Publishing the data source separately creates that reusable asset we talked about.

In the Data pane (top left), right-click on the name of your data source. In the context menu that appears, select Publish to Server....

Step 3: Configure the Publishing Options

This is the most important step, where you define how your published extract will behave. A dialog box will appear with several options:

• Project: From the dropdown menu, choose the project folder on the server where you want the data source to live.
• Name: Give your data source a clear and descriptive name. Good naming conventions are vital! For example, “[Marketing] - Monthly Campaign Performance” is much better than “Datasource_1_final”.
• Description: Add a brief description explaining what data is included, its refresh frequency, and who the owner is. This helps other users discover and trust your data source.
• Update Workbook to use the published data source: Always check this box! It automatically switches your current workbook to use the server version you are about to publish, saving you a manual step later.

Authentication - The Key to Automated Refreshes

Under the project selection, you’ll see an “Authentication” setting. Click Edit.

You’ll generally see two options:

• Prompt user: The viewer will be asked for database credentials every time they open a connected workbook. This is almost never what you want for a widely shared dashboard.
• Embedded password: THIS IS THE ONE! Select this option to securely store the database password on the server. This allows Tableau Server to connect to the source database and run the extract refresh automatically in the background without any human intervention.

Step 4: Push the Publish Button!

Once you’ve configured everything, click the blue Publish button. Tableau Desktop will create the extract, package it, and upload it to the server. Depending on the size of your extract, this might take a few moments.

Step 5: Set Up the Refresh Schedule on the Server

Your extract is now live, but it’s still just a static snapshot. The final step is to tell Tableau Server to refresh it automatically.

1. Navigate to your project on Tableau Server in a web browser.
2. You’ll see your newly published data source. Click on it.
3. Go to the Refresh Schedules tab.
4. Click New Refresh Schedule.
5. Choose an existing schedule from the list (e.g., “Daily 6am Refresh”) or work with your admin to create a new one. Select the schedule, choose your refresh type (usually “Full Refresh”), and click Create Schedule.

That’s it! Your extract will now query the original database on the schedule you set, ensuring that all connected dashboards have fresh data without any manual work.

Common Pitfalls and How to Avoid Them

Even with a clear process, a few common issues can trip people up during publishing or scheduling.

Refresh Fails Due to Credentials

Problem: Your scheduled refresh fails, and you get an email notification saying the login was incorrect. Solution: This is almost always an authentication issue. Either you forgot to select “Embedded password” during publishing, or the password for the source database has changed. Navigate to your data source on the server, go to the “Connections” tab, and edit the connection to update the embedded credentials.

Long Publishing/Refresh Times

Problem: Your extract takes a very long time to publish or refresh. Solution: The culprit is usually the size of your data. Before creating your extract, consider applying filters to only bring in the data you actually need (e.g., the last two years instead of all ten). You can also use the “Hide All Unused Fields” option to remove columns you aren’t using in your workbook, which can significantly shrink the extract size.

Permission Errors

Problem: You can’t see the project you want to publish to, or you get an error when you try. Solution: This is simply a permissions issue on Tableau Server. You need to contact your Tableau Server or site administrator and ask for “Publisher” permissions for the specific project where the data source needs to go.

Final Thoughts

Publishing your extracts to Tableau Server as a standalone data source is a fundamental best practice. It transforms a scattered, manual reporting process into a streamlined, automated, and governed analytics workflow, creating a single source of truth that empowers your entire team to make decisions with confidence.
