計算Excel文件中工作表的數量

Question

如何使用Java SE統計Microsoft Excel文件中的工作表數量？

Answer 1

有沒有標準類/庫在Java SE文件與MS Excel的接口。在Apache POI中，可以使用HSSFWorkbook.getNumberOfSheets()方法，該方法返回工作簿中工作表的數量。

要打開一個Excel文件，並得到HSSFWorkbook，這樣做：

String fileName = "C://Excel.xls"; 
POIFSFileSystem fileSystem = new POIFSFileSystem(new FileInputStream(fileName)); 
HSSFWorkbook workbook = new HSSFWorkbook(fileSystem); 

Answer 2

在WritableWorkbook類中使用getNumberOfSheets()。

這些看一看：

jxl.Workbook; 
jxl.write.Label; 
jxl.write.WritableSheet; 
jxl.write.WritableWorkbook;

Answer 3

使用下面的代碼來獲取工作表

FileInputStream file = new FileInputStream(new File(FILE PATH));    

XSSFWorkbook workbook = new XSSFWorkbook(file);   

System.out.println("number of sheet::"+ workbook.getNumberOfSheets()); 

Answer 4

的數量可以使用xlsx4j計數。這是我的代碼：

public static void main(String[] args) throws InvalidFormatException, Docx4JException { 
    SpreadsheetMLPackage spPackage = SpreadsheetMLPackage.load(new File("D:/MyFile.xlsx")); 
    List<Sheet> sheetList = spPackage.getWorkbookPart().getJaxbElement().getSheets().getSheet(); 
    System.out.println("Number of worksheet: "+ sheetList.size()); 
    System.out.println("Sheet name: "); 
    for (Sheet sheet : sheetList) { 
     System.out.println(sheet.getName()); 
    } 

Answer 5

public int getNumberOfSheets(File)throws Exception{ 
FileInputStream fileInputStream = new FileInputStream(file); 
HSSFWorkbook workbook = new HSSFWorkbook(fileInputStream); 
int number_of_sheets =  workbook.getNumberOfSheets(); 
return number_of_sheets 
} 

上面是一個簡單的方法來獲得在XLS工作簿
