XSSFSheet: Blatt-Index liegt außerhalb des Bereichs

Question

Ich versuche, den Inhalt der xlsx-Datei mit POI zu schreiben, aber habe eine IllegalArgumentException.

Im Anschluss ist mein Code:

public static void ConvertToCSVOrgtoOrg(String Scenario) throws Exception { 

    String IntermediateXLSXPath=GetFileDetailsSIF(Scenario,"ExcelPath"); 
    String IntermediateCSVPath=GetFileDetailsSIF(Scenario,"CSVPathOrgtoOrg"); 

    File inputFile = new File(IntermediateXLSXPath); 
    File outputFile = new File(IntermediateCSVPath); 
    // For storing data into CSV files 
    StringBuffer data = new StringBuffer(); 

    try { 
     FileOutputStream fos = new FileOutputStream(outputFile); 
     // Get the workbook object for XLSX file 
     XSSFWorkbook wBook = new XSSFWorkbook(new FileInputStream(inputFile)); 
     XSSFFormulaEvaluator.evaluateAllFormulaCells(wBook); 
     // Get first sheet from the workbook 
     XSSFSheet sheet = wBook.getSheetAt(18); 
     XSSFFormulaEvaluator.evaluateAllFormulaCells(wBook); 

     Row row; 
     Cell cell; 
     // Iterate through each rows from first sheet 
     Iterator<Row> rowIterator = sheet.iterator(); 

     while (rowIterator.hasNext()) { 
      row = rowIterator.next(); 
      data.append("\n"); 

      // For each row, iterate through each columns 
      Iterator<Cell> cellIterator = row.cellIterator(); 
      while (cellIterator.hasNext()) { 
       cell = cellIterator.next(); 

       switch (cell.getCellType()) { 
        case Cell.CELL_TYPE_BOOLEAN: 
         data.append(cell.getBooleanCellValue()); 
         break; 

        case Cell.CELL_TYPE_NUMERIC: 
         data.append(cell.getNumericCellValue()); 
         break; 

        case Cell.CELL_TYPE_STRING: 
         data.append(cell.getStringCellValue()); 
         break; 

        case Cell.CELL_TYPE_FORMULA: 
         data.append(cell.getStringCellValue()); 

        case Cell.CELL_TYPE_BLANK: 
         break; 
        default: 
       } 
      } 
     } 

     fos.write(data.toString().getBytes()); 
     Thread.sleep(1000); 
     fos.close(); 

    } catch (Exception ioe) { 
     ioe.printStackTrace(); 
    } 

} 

Die Ausnahme Ich erhalte ist:

Ich habe ein 18.es Blatt. Jede Hilfe würde sehr geschätzt werden.

Answer 1

... 
// Get first sheet from the workbook 
//XSSFSheet sheet = wBook.getSheetAt(18); Instead, 
XSSFSheet sheet = wBook.getSheetAt(17); 
... 

Wie Sie sagten, Sie haben nur 18 Excel-Tabellen in dieser Datei, wenn Sie das 18. Blatt in der Excel-Datei erhalten gehen, müssen Sie sich auf minus 1 von 18 Geben 17.

Index ist Start von 0 anstelle von 1.
