Open this file using a text editor like Notepad, you will see it is actually a CSV file: ConclusionSo far you have learned how to code CSV export function for a Spring Boot web application. The file name is something like this: users_05-25-56.csv. ![]() Test Export and Download CSV fileClick the hyperlink Export to CSV, the Spring Boot application will generate a CSV file and the browser will automatically download that file.
