Tableau’s magic lies in its ability to connect to multiple data sources, clean and transform data, and then visualize it in a way that makes insights easy to uncover. But how does it actually work?
1. Connecting to Data: Tableau can connect to a variety of data sources, including spreadsheets, databases, cloud services, and even big data platforms. Once connected, you can pull in the data you need for analysis.
2. Data Preparation: This is where Tableau Prep shines. You can use it to clean and shape your data, such as removing duplicates, filtering records, or combining datasets. The tool provides a visual interface that allows you to see the changes you’re making in real-time.
3. Data Analysis: After preparing your data, you can bring it into Tableau Desktop to create interactive dashboards, reports, and visualizations. Tableau’s drag-and-drop interface makes it easy to build complex analyses without writing a single line of code.
4. Sharing Insights: Once your analysis is complete, you can share your findings with others through Tableau Server or Tableau Online. These platforms allow you to publish your dashboards and reports securely, making it easy for others to interact with your data.

In today’s data-driven world, making sense of vast amounts of information can be overwhelming. But what if there was a tool that could help you clean, prepare, and visualize your data effortlessly? That’s where Tableau Prep comes in. This blog will walk you through what Tableau Prep is, why it’s a game-changer, how much it costs, how it works, and even how to create calculated fields in Tableau.
What is Tableau Prep?
In any data analysis process, one of the most time-consuming tasks is preparing the data for analysis. Whether it’s combining multiple datasets, cleaning up inconsistencies, or filtering out irrelevant information, data preparation can be a headache. This is where Tableau Prep comes to the rescue.
Tableau Prep is a data preparation tool designed to make data cleaning and shaping easier and faster. It enables you to connect to various data sources, clean and structure your data, and get it ready for analysis in Tableau Desktop or other BI tools. With its intuitive interface, drag-and-drop functionality, and real-time previews, even users with minimal technical expertise can transform raw data into actionable insights.
How to Create a Calculated Field in Tableau ?
One of Tableau’s most powerful features is its ability to create calculated fields. These are custom fields that you define using a formula, which can help you derive new insights from your data.
Here’s how to create a calculated field in Tableau:
- Open Tableau Desktop and load your dataset.
- Go to the Data pane on the left side of the screen, right-click on a blank space, and select “Create Calculated Field.”
- Enter a name for your calculated field in the dialog box that appears.
- Type your formula into the calculation editor. Tableau offers a wide range of functions you can use, such as mathematical operations, logical comparisons, and string manipulations.
- Click OK to save your calculated field. It will now appear in the Data pane, ready to be used in your visualizations.
How Much Does Tableau Cost?
The cost of Tableau varies depending on the product and the licensing model you choose. Tableau Prep is typically bundled with Tableau Desktop and Tableau Server/Online under the Tableau Creator license, which costs around $70 per user per month (billed annually). This license gives you access to Tableau Prep, Tableau Desktop, and Tableau Server/Online.
For those on a budget, Tableau also offers a free version called Tableau Public. However, this version has limitations, such as saving your work to Tableau’s public cloud, which may not be suitable for sensitive data.
