CLJ Excel framework and other libraries comparison and choice guide
CLJ Excel framework and other libraries comparison and choice guide
preface:
When processing the Excel file, CLJ Excel is a powerful and popular Clojure library.However, other types of libraries also provide similar functions compared to CLJ Excel.This article will compare CLJ Excel and other class libraries and provide you with a choice guide.The following is a comparison of CLJ Excel:
1. Clj Excel
CLJ Excel is an open source library for operating Excel.It provides many functions, including reading, writing, and operating Excel files.It is written in Clojure language and can be seamlessly integrated with Java.
Example code:
clojure
(require '[clj-excel.core :as excel])
(def workbook (excel/create-workbook))
(def sheet (excel/create-sheet workbook "Sheet1"))
(excel/set-cell-value sheet 0 0 "Hello, Clj Excel!")
(excel/save-workbook workbook "example.xlsx")
2. Apache POI
Apache Poi is a very popular Java class library for processing Microsoft Office files, including excel.It provides a wide range of functions, but sometimes it may be too complicated.
Example code:
import org.apache.poi.ss.usermodel.*;
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("Hello, Apache POI!");
try (FileOutputStream outputStream = new FileOutputStream("example.xlsx")) {
workbook.write(outputStream);
}
3. JExcelAPI
Jexcelapi is a Java class library for reading and writing to the excel file.It provides a simple and easy -to -use API and provides a comprehensive support for the Excel file.It is a very lightweight library that is suitable for small applications.
Example code:
import jxl.Workbook;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.Label;
WritableWorkbook workbook = Workbook.createWorkbook(new File("example.xls"));
WritableSheet sheet = workbook.createSheet("Sheet1", 0);
Label label = new Label(0, 0, "Hello, JExcelAPI!");
sheet.addCell(label);
workbook.write();
workbook.close();
Choose Guide:
1. If you use the Clojure language, CLJ Excel is a very convenient choice.It has a good Clojure integration and provides a set of powerful features.
2. If you use Java language, Apache Poi is a powerful and reliable choice.It has a wide range of functions and is suitable for various scenarios.
3. If you need a lightweight and functional library, and the performance is not high, Jexcelapi is a good choice.It can easily read and write the Excel file, suitable for small applications.
in conclusion:
When choosing a class library that is suitable for your Excel processing requirements, you should consider the programming language, the function and performance requirements you are using.Whether you choose CLJ Excel, Apache Poi, or Jexcelapi, they all provide strong functions and flexibility for the Excel file processing.
