Which file formats can Tableau Desktop connect to?

Tableau Desktop is designed to be highly versatile in terms of data connectivity, allowing users to connect to a wide variety of data sources. The correct answer highlights that Tableau can connect to multiple formats including Excel spreadsheets, CSV files, JSON, and various databases.

Excel files are commonly used in data analysis due to their easy organization of data into tables, while CSV (Comma-Separated Values) files are a standard format for data exchange between different applications. JSON (JavaScript Object Notation) provides a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate, making it increasingly popular in web applications and APIs. Additionally, Tableau can connect to a range of databases, providing options for users to work with structured data in various relational and non-relational databases, such as SQL databases, Oracle, and many more.

This capability to connect to multiple data formats enhances Tableau's functionality and flexibility, making it an ideal tool for data analysts who need to work with diverse data sources to create insightful visualizations. The other options do not capture the breadth of Tableau's connectivity capabilities, which is why they are not suitable answers.
