How to use the Excel Templateer framework in the Java library

Excel Templateer is a Java class library for generating and operating Excel files in Java applications.Excel Template provides a simple and flexible way to create and fill the Excel template, which can generate dynamic Excel documents by filling data.The following is how to use the Excel Templateer framework in the Java library. Step 1: Add Excel Templater library to the Java project First, you need to add the Excel Templator library to the construction path of the Java project.You can download the latest version of the library file (usually a jar file) from Excel Templateer's official website or repository.The method of adding library files to the project depends on the Java building tool you use, such as Maven or Gradle. Step 2: Create an excel template file Create an Excel template file in the project, which will be used as the basis for generating excel documents.You can use Microsoft Excel or any other electronic table application to create template files.Make sure that the data area to be filled in the template file can be made, and you can set a custom name or use a specific format in the cell (such as $ {variablename}). Step 3: Use Excel Templateer in Java code Use Excel TMPLER in the Java code to generate dynamic Excel documents.The following is the basic example of using Excel Templater: import com.libreoffice.templateengine.*; import java.io.*; public class ExcelGenerator { public static void main(String[] args) { try { // Load the excel template file File templateFile = new File("path/to/template.xlsx"); XlsxTemplate template = new XlsxTemplate(templateFile); // Create a data model TemplateData data = new TemplateData(); data.put("name", "John Doe"); data.put("age", 30); data.put("occupation", "Engineer"); // Fill in data to the template template.fill(data); // Save generated excel documentation File outputFile = new File("path/to/output.xlsx"); template.save(outputFile); System.out.println ("Excel document successfully!");); } catch (IOException e) { e.printStackTrace(); } catch (TemplateException e) { e.printStackTrace(); } } } In the above sample code, we first load the Excel template file, then create a data model and fill in the data into the template.We can use custom names in the data model to specify the fill position of the data (such as "name", "Age" and "Occupation").Finally, we save the generated Excel document into the specified output file. Summarize Excel Templateer is a Java class library that facilitates and operates Excel documents.By following the above steps, you can easily use Excel Templateer in Java applications to achieve the generation of dynamic Excel documents.
