我正在尝试在java中读取excel文件,修改它然后将其放入新的excel文件中。在那一刻我只是试图将读取数据直接放入一个新文件。我的问题是如何将cell.getContents()中的内容直接导入新文件
if(!f.exists()){
String FileName = "C:\\Users\\alexp\\Desktop\\New_Export.xls";
WritableWorkbook excel = Workbook.createWorkbook(new File(FileName));
WritableSheet sheet = excel.createSheet("Sheet1", 0);
for (int y = 0; y < page.getRows(); y++){
for (int x = 0; x < page.getColumns(); x++){
Cell cell = page.getCell(x ,y +1);
CellType type = cell.getType();
if(type == CellType.LABEL){
System.out.println(cell.getContents());
Label label1 = new Label();
sheet.addCell(label1);
if(type == CellType.NUMBER){
System.out.println(cell.getContents());
Number num1 = new Number ();
sheet.addCell(num1);
}
}
}
System.out.println(" ");
}
System.out.println("The File Has Successfully Been Created!");
excel.write();
excel.close();
}
else{
System.out.println("File is already created!");
}
答案 0 :(得分:0)
您可以使用apache poi读取Excel工作表的每一行,如下所示:
HssfRow row = sheet.getRow(rowIndex);
HssfCell cell = row.getCell(columnIndex);
FormulaEvaluator fe = workbook.getCreationHelper().createFormulaEvalator();
CellValue cv = fe.evaluate(cell);
希望这会对你有帮助,我已经从手机输入了这段代码,你可能会得到一些语法错误,纠正它们会起作用。祝你有愉快的一天: - )
