What Type of Data Can Tableau Read?

Tableau is a powerful data visualization tool that can read and analyze various types of data. Whether you are working with spreadsheets, databases, or big data sources, Tableau provides flexibility and ease of use.

In this article, we will explore the different types of data that Tableau can read and how to effectively work with them.


Tableau has excellent support for spreadsheet files such as Microsoft Excel (.xlsx) and CSV (Comma-Separated Values) files. When working with spreadsheets in Tableau, it’s important to ensure that your data is organized in a tabular format with headers for each column.

This allows Tableau to automatically detect the structure of your data and assign appropriate field types.

Database Connections

Tableau supports a wide range of databases including but not limited to MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and many more. To connect to a database in Tableau, you need to provide the necessary connection details such as server name, port number, username, password, and database name.

Once connected, you can import tables or write SQL queries directly within Tableau.

Big Data Sources

In addition to traditional databases and spreadsheets, Tableau can also connect to big data sources like Hadoop Distributed File System (HDFS), Amazon Redshift, Google BigQuery, and Apache Spark. These platforms handle massive amounts of data efficiently and Tableau allows you to leverage their power for visualizing complex datasets.

Data Warehouse Connections

Tableau has built-in connectors for popular data warehouse solutions like Amazon Redshift, Google BigQuery, Snowflake, and Microsoft Azure SQL Data Warehouse. These connectors provide optimized access to your data, ensuring high performance and scalability for your analytical needs.

Web Data Connectors

Tableau allows you to create custom web data connectors, which enable you to connect to web-based APIs and retrieve data in real-time. This feature is particularly useful when working with live data sources such as social media platforms, weather APIs, or financial data feeds.

Other File Formats

Apart from spreadsheets and databases, Tableau can also read other file formats like JSON (JavaScript Object Notation) and statistical files such as SAS and R. These formats are commonly used in data science and analytics workflows, and Tableau’s support for them enhances its versatility as a visualization tool.

  • JSON: Tableau can directly connect to JSON files or use JSON data within spreadsheets or databases.
  • SAS: Tableau can connect to SAS datasets (.sas7bdat) and leverage their statistical capabilities.
  • R: With the help of R integration, Tableau can connect to R scripts and utilize advanced analytics.

In conclusion, Tableau is a comprehensive tool that can read a wide range of data sources. Whether you are working with spreadsheets, databases, big data platforms, or specialized file formats like JSON or SAS, Tableau provides the necessary tools to analyze and visualize your data effectively.
