Comparison evaluation of the Fastexcel Writer framework with other Excel writing tools
The Fastexcel Writer framework is a high -performance Excel writing tool for Java language, which helps developers to generate and write Excel documents more easily.In this article, we will compare the Fastexcel Writer framework with other Excel writing tools and provide some Java code examples.
1. Performance comparative evaluation
In terms of performance, the Fastexcel Writer framework has the following advantages:
1. High -speed writing: Fastexcel Writer uses an efficient writing algorithm that can quickly generate a large amount of data and write it into the Excel document.
2. Low memory occupation: The Fastexcel Writer framework is very delicate and can minimize memory consumption. Even when processing large data sets, it can maintain lower memory occupation.
3. Asynchronous writing: Fastexcel Writer supports asynchronous writing operations, which can perform writing operations in the background thread to improve writing efficiency.
2. Functional evaluation
Compared with other Excel writing tools, the Fastexcel Writer framework has rich functions:
1. Support multiple data types: Fastexcel Writer can process various types of data, including numbers, string, date, Boolean value, etc.
2. Support the merger cell: Fastexcel Writer allows developers to merge the cell to create a more complex Excel layout.
3. Support setting cell style: Fastexcel Writer provides rich cell style options, which can set fonts, color, background and other attributes.
4. Support image insertion: Fastexcel Writer can insert the picture into the excel document to make the generated document richer and diverse.
Third, use examples
Below is an example code that uses the Fastexcel Writer framework to demonstrate how to use this framework to generate a simple Excel document:
import com.github.houbb.iexcel.ExcelWriter;
import com.github.houbb.iexcel.util.excel.InnerExcelBuilder;
import com.github.houbb.iexcel.util.excel.vo.ExcelStyle;
import com.github.houbb.iexcel.util.excel.vo.InnerStyle;
import com.github.houbb.opencc4j.util.ZhConverterUtil;
import java.util.ArrayList;
import java.util.List;
public class FastExcelWriterExample {
public static void main(String[] args) {
// Create a data set
List<String> data = new ArrayList<>();
data.add ("name");
data.add ("age");
data.add ("Gender");
// Create ExcelBuilder
InnerExcelBuilder builder = ExcelWriter.createExcelBuilder();
// Set the header style
InnerStyle headerStyle = InnerStyle.build(ExcelStyle.buildDefaultFont("Arial", 12, true))
.setBackColor("#DCE6F1")
.setAlignment(InnerStyle.Alignment.CENTER);
builder.setHead(data, headerStyle);
// Set the data line style
InnerStyle rowStyle = InnerStyle.build(ExcelStyle.buildDefaultFont("Arial", 10))
.setAlignment(InnerStyle.Alignment.CENTER);
for (int i = 1; i <= 10; i++) {
List<String> rowData = new ArrayList<>();
rowdata.add ("Little Ming" + i);
rowData.add(String.valueOf(20 + i));
Rowdata.add (I % 2 == 0? ":" Woman ");
builder.appendBody(rowData, rowStyle);
}
// Save the excel file
builder.writeFile("example.xlsx");
}
}
The above code demonstrates how to use the Fastexcel Writer framework to generate an Excel document containing the header and data.First, we created a data set and set it to the header.Then, we added 10 lines of data and set the line style.Finally, we call the `` WRITEFILE "method to save the generated Excel files to the local.
In summary, the Fastexcel Writer framework is a powerful Excel writing tool with high performance, rich functions and easy -to -use APIs.Developers can use it to quickly generate complex Excel documents and meet various writing needs.
