I want to read the data from the Excel in selenium using java, but it is throwing the exception as below:
"main" java.lang.ExceptionInInitializerErrorat org.apache.poi.ss.util.CellReference.<init>(CellReference.java:110).
Tried multiple ways, but still getting the exception of main.
I have created the folder as "excel" in the selenium project, in which I have pasted the excel.

}
public static void ReadExcel()

File src = new File("C:....");
FileInputStream fis = new FileInputStream(src);
XSSFWorkbook wb = new XSSFWorkbook("fis");
XSSFSheet sheet1 = wb.getSheetAt(0);
String data0 =sheet1.getRow(0).getCell(0).getStringCellValue();
System.out.println("Data from Excel is "+data0);
}
This is wrong:
XSSFWorkbook wb = new XSSFWorkbook("fis");
should be:
XSSFWorkbook wb = new XSSFWorkbook(fis);
Tested with file like
and modified class:
package utils;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

}
public static void ReadExcel() throws IOException {
File src = new File("C:\\test.xlsx");
FileInputStream fis = new FileInputStream(src);
XSSFWorkbook wb = new XSSFWorkbook(fis);
XSSFSheet sheet1 = wb.getSheetAt(0);
String data0 = sheet1.getRow(0).getCell(0).getStringCellValue();
System.out.println("Data from Excel is " + data0);
// don't forget to close the workbook
wb.close();
}
}
Output:
Data from Excel is FOO
PS: I'm using Apache POI 4.1.2
Reading an excel sheet is basically called as utils, don't mixed reading data code, and your automation code
create utils class and use (property file reader)
The formula didn't work at new workbook when I try to clone an old workbook to new workbook. it just displayed value of 0. It might only work when I double-click on it and enter :(

i am trying to compare the filenames with the xlsx sheet ...if the filename matches with the value of the excel sheet...i want to delete that particular row from the excel sheet....
below is the code what i have tried so far ...

for(int i=0;i<row;i++){
XSSFRow r=sheet.getRow(i);
String m=cellToString(r.getCell(0));
if(s.equals(m)){
System.out.println(m);
}
}
}
public static String cellToString(XSSFCell cell) {
int type;
Object result = null;
type = cell.getCellType();
switch (type) {
case XSSFCell.CELL_TYPE_STRING:
result = cell.getStringCellValue();
break;
case XSSFCell.CELL_TYPE_BLANK:
result = "";
break;
case XSSFCell.CELL_TYPE_FORMULA:
result = cell.getCellFormula();
}
return result.toString();
}
}
here 's' is the variable to hold filenames and 'm' is the variable to hold excel values
The PROBLEM is:
if i use
if(s.equals(m))
{
System.out.println(m);
}
HOW TO DELETE THE MATCHED ROW FROM THE EXCEL???
Eg)
File names:
a.xlsx
b.xlsx
c.xlsx
excel.xlsx
a
b
d
c
i want to remove a and b from the excel.xlsx
UPDATED:
Based on YASH suggustion i tried the below code
if(s.equals(m)){
System.out.println(m);
sheet.removeRow(r);
}
it removed the first value from excel.xlsx(a)....and shows Exception in thread "main" java.lang.NullPointerException error in the below line
String m=cellToString(r.getCell(0));
i tried with
XSSFRow r = sheet.getRow(i);
if(r==null){
continue;
}
it takes only two values(a,b) from excel.xlsx
After removing the row with RemoveRow(r) shift the remaining rows by 1 as shown below to avoid NullPointer Exception
sheet.RemoveRow(r);
int rowIndex = r.RowNum;
int lastRowNum = sheet.LastRowNum;
if (rowIndex >= 0 && rowIndex < lastRowNum)
{
sheet.ShiftRows(rowIndex + 1, lastRowNum, -1);
}
finally i got the answer

You are only reading the file and not writing it. You have to put something like this in the end:
FileOutputStream out = new FileOutputStream(new File("..."));
workbook.write(out);
out.close();
