Pros of POI

• More comprehensive support for various Microsoft Office formats (Excel, Word, PowerPoint, etc.)
• Longer history and larger community support
• More feature-rich, offering advanced functionality for complex document manipulation

Cons of POI

• Higher memory consumption, especially for large files
• Steeper learning curve due to its extensive API
• Slower performance compared to EasyExcel for simple Excel operations

Code Comparison

POI:

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("Hello, POI!");

EasyExcel:

EasyExcel.write("output.xlsx", ExcelModel.class)
    .sheet("Sheet1")
    .doWrite(Arrays.asList(new ExcelModel("Hello, EasyExcel!")));

Summary

POI offers a more comprehensive solution for working with various Microsoft Office formats, while EasyExcel focuses specifically on Excel operations with improved performance and ease of use. POI provides more advanced features but comes with higher memory usage and a steeper learning curve. EasyExcel, on the other hand, offers a simpler API and better performance for basic Excel tasks, making it a good choice for projects primarily dealing with Excel files.

Pros of XlsxWriter

• Written in Python, offering seamless integration with Python projects
• Supports a wide range of Excel features, including charts, images, and data validation
• Excellent documentation and extensive examples

Cons of XlsxWriter

• Limited to writing Excel files, cannot read or modify existing files
• May have slower performance for very large datasets compared to EasyExcel

Code Comparison

XlsxWriter:

import xlsxwriter

workbook = xlsxwriter.Workbook('example.xlsx')
worksheet = workbook.add_worksheet()
worksheet.write('A1', 'Hello Excel')
workbook.close()

EasyExcel:

EasyExcel.write("example.xlsx", ExampleData.class)
    .sheet("Sheet1")
    .doWrite(dataList);

Key Differences

• XlsxWriter is Python-based, while EasyExcel is Java-based
• EasyExcel focuses on simplicity and ease of use for reading and writing Excel files
• XlsxWriter offers more advanced Excel features but is limited to writing files
• EasyExcel provides better performance for large datasets and memory optimization

Both libraries are popular choices for working with Excel files, with XlsxWriter being more suitable for Python developers and EasyExcel catering to Java developers. The choice between them depends on the specific project requirements, programming language preference, and desired Excel features.

Pros of PhpSpreadsheet

• More mature and widely adopted in the PHP ecosystem
• Supports a broader range of spreadsheet formats (XLSX, XLS, ODS, CSV, HTML)
• Extensive documentation and community support

Cons of PhpSpreadsheet

• Generally slower performance, especially with large datasets
• Higher memory consumption compared to EasyExcel
• Steeper learning curve for beginners

Code Comparison

PhpSpreadsheet:

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World!');
$writer = new Xlsx($spreadsheet);
$writer->save('hello_world.xlsx');

EasyExcel:

EasyExcel.write("hello_world.xlsx", DemoData.class)
    .sheet("Sheet1")
    .doWrite(data());

While both libraries aim to simplify spreadsheet manipulation, EasyExcel focuses on performance and ease of use for Java developers, particularly when dealing with large datasets. PhpSpreadsheet offers more comprehensive features and format support for PHP projects but may require more resources. The code comparison highlights the simplicity of EasyExcel's API compared to PhpSpreadsheet's more verbose approach.

Pros of sheetjs

• Broader language support, including JavaScript, TypeScript, and various frameworks
• More comprehensive file format support, including legacy Excel formats
• Larger community and ecosystem, with more resources and third-party integrations

Cons of sheetjs

• Steeper learning curve due to more complex API
• Larger file size, which may impact performance in some applications
• Commercial use requires a paid license

Code Comparison

easyexcel (Java):

EasyExcel.read("demo.xlsx", DemoData.class, new DemoDataListener())
    .sheet()
    .doRead();

sheetjs (JavaScript):

const workbook = XLSX.readFile('demo.xlsx');
const worksheet = workbook.Sheets[workbook.SheetNames[0]];
const data = XLSX.utils.sheet_to_json(worksheet);

Both libraries provide straightforward methods for reading Excel files, but easyexcel's API is more concise and tailored for Java developers. sheetjs offers more flexibility and options, but requires more code to achieve similar results.

easyexcel is specifically designed for Java applications and excels in handling large Excel files with low memory usage. It's particularly well-suited for server-side processing in Java environments.

sheetjs, on the other hand, offers broader language and format support, making it a versatile choice for web applications and cross-platform development. However, its larger file size and more complex API may be considerations for some projects.
