Introduction to Tableau Prep Builder

Tableau Prep Builder is a Tableau product designed to help everyone quickly and confidently combine, shape, and clean their data for analysis.

How to Get Tableau Prep Builder

What's New in Tableau Prep Builder 2019.3.1

Start by reading this blog post by Anton Grinevskij, Senior Software Engineer at Tableau

Introducing support for custom R and Python scripts in Tableau Prep flows

Note: Starting in version 2019.1.2, Tableau Prep is now called Tableau Prep Builder. This name change is to distinguish it from the new Tableau Prep Conductor which runs on Tableau Server as an add-on. With the launch of Conductor, the work you do in Prep Builder running on your Tableau Desktop, can be saved to run in a centralized, scalable, and reliable server environment so your data is always up to date and easy to share.



New Language Added: Italian

Tableau Prep Builder and Support Knowledge Base now available in Italian!  


With the launch of Tableau Prep Builder 2019.3.1 as well as Tableau Desktop and Server 2019.3, Italian has been added to our supported languages. Tableau customers come from all corners of the world and we want to serve as many as possible in their native languages.

Explore Support Knowledge Base in all 11 languages.


Connect to Data

Connect to data using Google BigQuery   


Connect to even more of your data in the cloud using Google BigQuery. Like Tableau Desktop, you can now connect to data stored in Google BigQuery and publish flows to Tableau Server and Tableau Online if Google OAuth connections are configured.

Note: Tableau Prep Builder does not currently support using Google BigQuery customization attributes.

For more information about how to connect to Google BigQuery, see Google BigQuery in the Tableau Desktop help. For more information about connecting to data and building a flow, see Connect to Data.


Connect to published data sources for flow input  


Whether you generate a published data source from Tableau Desktop or as output from Tableau Prep Builder and publish it to Tableau Server or Tableau Online, you can now connect to your published data sources and use them as an input data source for your flow.

Simply select Tableau Server from the Connect pane, then sign in to your server or site. After you sign in, a list of available data sources are shown. Select your data source, or use the search option to find your data source and drag it to the flow pane to start your flow.

Note: Published data sources that include user filters are not currently supported.

For more information about connecting to data and building a flow, see Connect to Data.


Clean and Shape Data

Use R and Python scripts in your flow   


You can now use R and Python scripts to perform more complex cleaning operations or incorporate predictive modeling data into your flow. Data is passed from the flow as input through the R or Python script step using Rserve or TabPy, then returned as output data that you can continue cleaning using the features and functions in Tableau Prep Builder.

For more information about how to include scripts in your flow, see Use R and Python scripts in your flow.


Keep Flow Data Fresh

Publish flows to Tableau Online   


You can now publish your flows to either Tableau Server or Tableau Online and run them on a schedule to keep data fresh. Tableau Online does not support direct connections to on-premise data sources. If you publish a flow to Tableau Online that connects to an on-premise data source, you can edit your connection to automatically convert the connection to a published data source.

For more information about publishing flows to Tableau Online, see Publish a Flow to Tableau Server or Tableau Online.


Tableau Prep Conductor and Tableau Online

Part of the Data Management Add-on   


Tableau Prep Conductor is included in the separately licensed Data Management Add-on for Tableau Server and Tableau Online. Tableau Prep Conductor leverages the scheduling and tracking functionality of Tableau Online so you can automate running flows to update the flow output instead of logging into Tableau Prep to manually run individual flows as your data changes.

For more information, see Tableau Prep Conductor and License the Data Management Add-on.


Compatibility

Tableau Prep Builder is a stand-alone product that works seamlessly with Tableau Desktop, Tableau Server and Tableau Online. At any point while working in Tableau Prep Builder, you can create an extract of your data, publish your data source to Tableau Server or Tableau Online, or even open Tableau Desktop directly from Tableau Prep Builder to preview your data.

  • Tableau Prep Builder works on Windows and Mac. It can create Tableau Extracts (.tde and .hyper) and CSV files that can be used in Tableau 10.0 and later versions of Tableau.
  • In Tableau Prep Builder you can connect to many of the same data sources available in Tableau Desktop, Server and Online. For a complete list of Tableau supported data source, click here.
  • With some data sources, you may need to install drivers before connecting to your data. If this is the case, see the Driver Download page.

New Workspace for Faster Speed to Insight

Tableau Prep Builder uses Tableau’s data connectors, calculation language, and governance structure, making it possible to get you up to speed quickly and ready to collaborate at any point in the analytical process.

The Tableau Prep Builder workspace consists of the connections pane, the changes pane, and three coordinated areas designed to help you interact with and explore your data:

  1. Connections pane: The Connections pane shows the databases and files you are connected to. Add connections to one or more databases and then drag the tables you want to work with into the flow pane. 
  2. Flow pane: As you connect to, clean, shape, and combine your data, steps appear in the flow pane. You can hover over the icons at the top of each step to see what changes were made. 
  3. Profile pane: The profile pane in the center of the workspace shows a summary of each field in your data sample. This is where users can see the shape of the data and quickly find outliers and nulls.
  4. Changes pane: Tableau Prep Builder keeps track of any changes you make, in the order you make them, so you can always go back and review or edit those changes if needed.
  5. Data grid: The data grid shows the row level detail for your data. The values displayed reflect the operations defined in the profile pane. You can filter, keep only, and exclude individual field values in this grid plus drag and drop fields to change the display order.

For complete descriptions, including a video, see Workspace in Product Help.

Saving and Sharing Outputs

Defining Output

Tableau Prep Builder can save three types of files:

  1. .tfl files containing a flow
  2. .tflx files containing a flow and local file-based data sources, such as Excel and text files
  3. Output files containing the results of running a flow

Output files can be saved in .hyper, .tde and .csv formats, and are defined in the Output Step. The output files can be opened in Tableau Desktop, and published to Tableau Server or Tableau Online.

Tableau Desktop

Running the flow on Tableau Desktop results in a Tableau Data Extract file, either a .tde or .hyper depending your version of Tableau, either one saved in your Tableau Repository in the Datasources folder. It can also be output to .csv files, if you need to use your prepared data for other tools or processes.

Note! Once an extract has been created, whether .tde or .hyper, and a workbook based on it, the same compatibility rules for use with different versions of Tableau applies as in other usage situations. For more information, see Make Workbooks Compatible Between Versions.

Tableau Server

To publish your output to Tableau Server, use the Publish menu in Tableau Prep Builder. The Tableau Server REST API must be enabled in order to receive publish requests from Tableau Prep Builder. For more information see REST API Requirements.

Tableau Online

You can also use Tableau Prep Builder's Publish menu to publish your output to Tableau Online as a .hyper extract, .tde extract, or .csv file, and provide centralized access to the data you have cleaned, formatted, and combined.

We’re moving fast and will be launching new features frequently for Tableau Prep Builder, independent of the Tableau Desktop, Tableau Server or Tableau Online release cycles. Customers will need to upgrade to the latest version of Tableau Prep Builder to take advantage of new features and product fixes.
