After that, you can jump to the code for report generation. ![]() This allows iterating the list of persons with their details. Name,Age,Birthĭefine the following template in TXT or DOCX format. Provide CSV data source and template to simple method to generate PDF report.įor the PDF report generation, I will be using the following sample CSV data of different persons along with their respective ages and date of birth.Define template according to the CSV data.The following steps will lead you to convert CSV data into a formatted PDF report. Let’s start with the transformation of data into presentable PDF. Generate PDF Report from CSV Data in Java # You may download the JAR file from the downloads section, or just get the repository and dependency configurations for the pom.xml of your maven-based Java applications. It also supports report generation automation from multiple data sources like JSON, XML, and also from MS Word, Excel, and PowerPoint files as data files. GroupDocs.Assembly for Java is the report generation API that I have used in this article to generate reports from the selected CSV data and a template in TXT format. ![]() This article will guide you to convert CSV data into PDF and MS Word reports in Java using a simple template. As a developer, we often need to convert the large CSV data into a presentable format. CSV is widely used for exchanging data among applications. If you sign in using your Google account, you can download random data programmatically by saving your schemas and using curl to download data in a shell script via a RESTful url.The Comma Separated Values (CSV) is a file format for storing the data in the form of plain text where the values are separated by commas. Mockaroo allows you to quickly and easily to download large amounts of randomly generated test data based on your own specs which you can then load directly into your test environment using SQL or CSV formats. But not everyone is a programmer or has time to learn a new framework. There are plenty of great data mocking libraries available for almost every language and platform. Testing with realistic data will make your app more robust because you'll catch errors that are likely to occur in production before release day. Real data is varied and will contain characters that may not play nice with your code, such as apostrophes, or unicode characters from other languages. When you demonstrate new features to others, they'll understand them faster. When your test database is filled with realistic looking data, you'll be more engaged as a tester. Worse, the data you enter will be biased towards your own usage patterns and won't match real-world usage, leaving important bugs undiscovered. If you're hand-entering data into a test environment one record at a time using the UI, you're never going to build up the volume and variety of data that your app will accumulate in a few days in production. In production, you'll have an army of users banging away at your app and filling your database with data, which puts stress on your code. If you're developing an application, you'll want to make sure you're testing it under conditions that closely simulate a production environment. Paralellize UI and API development and start delivering better applications faster today! Why is test data important? With Mockaroo, you can design your own mock APIs, You control the URLs, responses, and error conditions. ![]() By making real requests, you'll uncover problems with application flow, timing, and API design early, improving the quality of both the user experience and API. ![]() It's hard to put together a meaningful UI prototype without making real requests to an API. Mock your back-end API and start coding your UI today.
