java - Creating a copy of an excel file is not working as expected -


i want copy entire content of 1 excel(.xls) after replacing " , '. however, code creating new excel copying last column(in case, 7th column). please advice going wrong code...

public class rename {

static hssfrow row_read = null; static hssfrow row_write = null; static cell cell; static fileoutputstream output = null; static hssfworkbook workbook_read = null; static hssfworkbook workbook_write = null; static hssfsheet sheet_read = null; static hssfsheet sheet_write = null; public static void removechar() { try{ fileinputstream input = new fileinputstream("inputpath//test_input.xls"); workbook_read = new hssfworkbook(input); sheet_read = workbook_read.getsheet("report"); workbook_write = new hssfworkbook(); sheet_write = workbook_write.createsheet("test"); dataformatter formatter = new dataformatter(); int rowcount = sheet_read.getlastrownum(); system.out.println(rowcount); for(int rownum = 0; rownum<=rowcount; rownum++) { for(int cellnum = 0; cellnum<=7; cellnum++) { //cell cell = null; row_read=sheet_read.getrow(rownum); row_write = sheet_write.createrow(rownum); string temp = formatter.formatcellvalue(row_read.getcell(cellnum)); //system.out.println(temp); string temp1 = temp.replaceall("\'", ""); string temp2 = temp1.replaceall("\"", ""); system.out.println(temp2); cell = row_write.createcell(cellnum); cell.setcellvalue(temp2); } }  output = new fileoutputstream("outputpath\\test_output.xls"); workbook_write.write(output);  } catch(exception e) {     e.printstacktrace(); }  } public static void main(string[] argv) throws ioexception {     rename.removechar();  }

}

thank

the issue following lines..

row_read=sheet_read.getrow(rownum); row_write = sheet_write.createrow(rownum);

it need outside cell loop (for(int cellnum = 0; cellnum<=7; cellnum++))

it should like.

 (int rownum = 0; rownum <= rowcount; rownum++) {             row_read = sheet_read.getrow(rownum);             row_write = sheet_write.createrow(rownum);             (int cellnum = 0; cellnum <= 7; cellnum++) {                 // cell cell = null; string temp =  formatter.formatcellvalue(row_read.getcell(cellnum));

also might need change import static cell cell; import hssfcell cell;

here complete code.

import java.io.fileinputstream; import java.io.fileoutputstream; import java.io.ioexception;  import org.apache.poi.hssf.usermodel.hssfcell; import org.apache.poi.hssf.usermodel.hssfrow; import org.apache.poi.hssf.usermodel.hssfsheet; import org.apache.poi.hssf.usermodel.hssfworkbook; import org.apache.poi.ss.usermodel.dataformatter;  public class rename {       static hssfrow row_read = null;     static hssfrow row_write = null;     static hssfcell cell;      static fileoutputstream output = null;     static hssfworkbook workbook_read = null;     static hssfworkbook workbook_write = null;     static hssfsheet sheet_read = null;     static hssfsheet sheet_write = null;      public static void removechar() {         try {             fileinputstream input = new fileinputstream("d://test_input.xls");             workbook_read = new hssfworkbook(input);             sheet_read = workbook_read.getsheet("report");             workbook_write = new hssfworkbook();             sheet_write = workbook_write.createsheet("test");             dataformatter formatter = new dataformatter();             int rowcount = sheet_read.getlastrownum();             system.out.println(rowcount);             (int rownum = 0; rownum <= rowcount; rownum++) {                 row_read = sheet_read.getrow(rownum);                 row_write = sheet_write.createrow(rownum);                 (int cellnum = 0; cellnum <= 7; cellnum++) {                     // cell cell = null;                     string temp = formatter.formatcellvalue(row_read.getcell(cellnum));                     // system.out.println(temp);                     string temp1 = temp.replaceall("\'", "");                     string temp2 = temp1.replaceall("\"", "");                     system.out.println(temp2);                     cell = row_write.createcell(cellnum);                     cell.setcellvalue(temp2);                 }             }              output = new fileoutputstream("d://test_output.xls");             workbook_write.write(output);          } catch (exception e) {             e.printstacktrace();         }      }      public static void main(string[] argv) throws ioexception {         rename.removechar();     } }
