Incompatible operand types int and CellType

So I am trying to read an excel sheet using Java code. Below is the code:
package com.SfHawk.Utility;
import org.apache.poi.hssf.usermodel.HSSFDateUtil;
import org.apache.poi.ss.usermodel.CellType;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileInputStream;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
public class ExcelApiTest {
public FileInputStream fis = null;
public XSSFWorkbook workbook = null;
public XSSFSheet sheet = null;
public XSSFRow row = null;
public XSSFCell cell = null;
public ExcelApiTest(String xlFilePath) throws Exception
{
fis = new FileInputStream(xlFilePath);
workbook = new XSSFWorkbook(fis);
fis.close();
}
public String getCellData(String sheetName, String colName, int rowNum)
{
try
{
int col_Num = -1;
sheet = workbook.getSheet(sheetName);
row = sheet.getRow(0);
for(int i = 0; i < row.getLastCellNum(); i++)
{
if(row.getCell(i).getStringCellValue().trim().equals(colName.trim()))
col_Num = i;
}
row = sheet.getRow(rowNum - 1);
cell = row.getCell(col_Num);
if(cell.getCellType() == CellType.STRING)
return cell.getStringCellValue();
else if(cell.getCellType() == CellType.NUMERIC || cell.getCellType() == CellType.FORMULA)
{
String cellValue = String.valueOf(cell.getNumericCellValue());
if(HSSFDateUtil.isCellDateFormatted(cell))
{
DateFormat df = new SimpleDateFormat("dd/MM/yy");
Date date = cell.getDateCellValue();
cellValue = df.format(date);
}
return cellValue;
}else if(cell.getCellType() == CellType.BLANK)
return "";
else
return String.valueOf(cell.getBooleanCellValue());
}
catch(Exception e)
{
e.printStackTrace();
return "row "+rowNum+" or column "+colNum +" does not exist in Excel";
}
}
}
Above code is giving me an error saying:
Incompatible operand types int and CellType
Initially I used cell.getCellTypeEnum() method instead of cell.getCellType(). But cell.getCellTypeEnum() gave me error saying, The method getCellTypeEnum() is undefined for the type XSSFCell
How can i fix this issue?
Thanks in advance.

gettting exception while reading duplicate column name excel file using sparkexcel library. How to overcome this issue

I am using spark-excel(com.crealytics.spark.excel) library to read excel file. If no duplicate column in excel file, the library working fine. If any duplicate column name occurs in excel file, throwing below exception.
How to overcome this error?
Is there any workaround solution to overcome this?
Exception in thread "main" org.apache.spark.sql.AnalysisException: Found duplicate column(s) in the data schema: `net territory`;
at org.apache.spark.sql.util.SchemaUtils$.checkColumnNameDuplication(SchemaUtils.scala:85)

Using spark excel API getting exception .
StructType schema = DataTypes.createStructType(new StructField[]{DataTypes.createStructField("CGISAI", DataTypes.StringType, true), DataTypes.createStructField("SALES TERRITORY", DataTypes.StringType, true)});
SQLContext sqlcxt = new SQLContext(jsc);
Dataset<Row> df = sqlcxt.read()
.format("com.crealytics.spark.excel")
.option("path", "file:///"+siteinfofile)
.option("useHeader", "true")
.option("spark.read.simpleMode", "true")
.option("treatEmptyValuesAsNulls", "true")
.option("inferSchema", "false")
.option("addColorColumns", "False")
.option("sheetName", "sheet1")
.option("startColumn", 22)
.option("endColumn", 23)
//.schema(schema)
.load();
return df;
This is the code I am using. I am using sparkexcel library from com.crealytics.spark.excel.
I want the solution to identify whether excel file has duplicate columns or not. if have duplicate columns, how to rename/eliminate the duplicate columns.
WorkAround is as below:
convert .xlsx file into .csv . using spark default csv api that can handle duplicate column names by renaming them automatically.
Below is the code to convert from xlsx to csv file.

reading multiple csv files and putting it in different sheets in excel not working

I am trying to read few csv files which are present inside a folder and putting the absolute paths inside a list and then looping to the list and inserting data into excel in different sheets but for some reason only last loop is overwriting everything.
package excel;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
public class FileReading {
public static void csvToXLS(String filename, String sheetno) {
try {
String csvFile = filename; //csv file address
String excelFile = "E:\\test.xls"; //xlsx file address
HSSFWorkbook workBook = new HSSFWorkbook();
HSSFSheet sheet = workBook.createSheet(sheetno);
String currentLine = null;
int RowNum = 0;
BufferedReader br = new BufferedReader(new FileReader(csvFile));
while ((currentLine = br.readLine()) != null) {
String str[] = currentLine.split(",");
HSSFRow currentRow = sheet.createRow(RowNum);
RowNum++;
for (int i = 0; i < str.length; i++) {
currentRow.createCell(i).setCellValue(str[i]);
}
}
FileOutputStream fileOutputStream = new FileOutputStream(excelFile);
workBook.write(fileOutputStream);
fileOutputStream.close();
System.out.println("Done");
} catch (Exception ex) {
System.out.println(ex.getMessage() + "Exception in try");
}
}
public static List listOfFiles() {
List<String> results = new ArrayList<String>();
File[] files = new File("f:\\csv").listFiles();
for (File file : files) {
if (file.isFile()) {
results.add(file.getAbsolutePath());
}
}
return results;
}
public static void main(String[] args) {
List list = listOfFiles();
int size = list.size();
for (int i = 0; i < size; i++) {
csvToXLS(list.get(i).toString(), "sheet" + i + 1);
}
}
}

You're re-creating and saving the Workbook every time you call csvToXLS, so only the last call survives, overwriting all others.
Create the Workbook only once, before you start your for loop, passing it into csvToXLS. then that method will create a new Sheet on an existing Workbook. Then after the for loop ends, you can write out and save the Workbook.

I did this thanks for the idea #rgettman

Poi Formula evaluation Error

I am using poi-3.8-20120326.jar and Excel 2007, trying to collect all the cell value in one list.
I am using formula for date increment operation. For example: =(i2+3) for k2 cell.
While evaluating this formula through my java code returns #VALUE! (i2 is a date cell.)

Without source it's hard to guess what's wrong, but I think that are two things that you may forget.
1) FormulaEvaluator
2) DataFormatter
Take a look at example.
