使用 for 循环读取 Excel 表和 Apache POI 而没有 header

Question

I want to read Excel file without a header using for loop and want to use that data to pass to another method. I'm unable to do so. Without header works fine.

@DataProvider(name = "inputData")

public static Object[][] getExcelData() throws IOException {

        inputStream = new FileInputStream(Constants.TEST_DATA);

        workbook = new XSSFWorkbook(inputStream);

        sheet = workbook.getSheet("CRMData");

        int rowCount = sheet.getLastRowNum() + 1;

        int columnCount = sheet.getRow(0).getLastCellNum();

        Object[][] data = new Object[rowCount][columnCount];

        for (int i = 0; i < rowCount; i++) {
            row = sheet.getRow(i);

            for (int j = 0; j < columnCount; j++) {
                cell = row.getCell(j);
                data[i][j] = cell.getStringCellValue();

            }
        }

        workbook.close();
        return data;
    }

I expect this method to fetch only test data, not the header, and pass that data to my test case for execution.

Answer 1

You mean as in:

for (int i = 1; i < rowCount; i++) {
    row = sheet.getRow(i);

    for (int j = 0; j < columnCount; j++) {
        cell = row.getCell(j);
        data[i - 1][j] = cell.getStringCellValue();
    }
}

That is, start from the second row?

Answer 2

If you want to skip header means top row of your excel file initialize value of i for the for loop with 1 which is responsible to traverse within rows. Top row used to have index value 0. So your for loop code for row and columns should be like this.

 Object[][] data = new Object[rowCount][columnCount];
        for (int i = 1; i < rowCount; i++) {
            XSSFRow row = sheet.getRow(i);

            for (int j = 0; j < columnCount; j++) {
                XSSFCell cell = row.getCell(j);
                data[i][j] = cell.getStringCellValue();
                System.out.println(data[i][j]);
            }

        }
