Reading/Writing Excel Files

I'm looking for a relatively straightforward way to read data from a .xls file and write out to another one using only standard java facilities, so no open source library suggestions please.

Excel can be accessed via JDBC, have a search for that, can't remember the details - just a JDBC name string. But really your best choice is the Jxl or JExcel (or whatever it's called) library. Apache POI is to be avoided, having the curious distinction of being both bloated and incomplete, as well as shocking performance.

Problem in reading the excel file path in WINDOWs machine from UNIX environ

Hello friends,
My requirement is to read each row of the excel sheet and sent that row to the database. I have implemented it by using jxl and apache poi framework. locally in my WINDOWS machine it is working fine..
But when i deploy the code in UNIX machine. My application runs on a Unix server , trying to read the excel file in WINDOWS environment. I am not able to retrieve the file path. for ex : C:\Documents and Settings\sabbanik\My Documents\KARUNAKAR\excel.xls
I am getting error in this line
workbook = Workbook.getWorkbook(filepath)
Error message : input file not found.
Thanks in advance..

You said: I am getting error in this line workbook = Workbook.getWorkbook(filepath) >
Based on this, I will assume you are trying to use OLE to access information about the Excel file. As mentioned by Andreas, your code will be executing on the server (Unix) and since Excel isn't on the server (and cannot be) an error will result. OLE can only be used in Windows environments (client or server). To access client side OLE calls and content, you need a java bean and Excel installed on the client machine. Oracle provides WebUtil as an option to writing your own Java Bean. To use this, you will need to be running Forms 10.1.2 or newer. Details can be found here along with a demo:

Dear All
I have a requirement to read/write excel files in .xlsx format. I am good in doing it with .xls format using jxl.jar. The jxl.jar doesn't support .xlsx format. Kindly help me in understanding how do I need to proceed on reading/writing .xlsx files using Webdynpro for Java.
Thanks and Regards

i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class
file for java.lang.Iterable. Fix the classpath then try rebuilding this project.
This compilation unit indirectly references the missing type java.lang.Iterable
(typically some required class file is referencing a type outside the classpath)
how can i resolve it

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename
     *        args [1] = destination filename
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {
            System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");

If the "it" refers to a compressed (zipped) spreadsheet that you downloaded, the ".ods" extension is used by LibreOffice and probably OpenOffice (which are free versions of MS Office) for spreadsheets, which would suggest that wherever you're getting that "Excel" file from has switched to one of those programs. I've tried opening an .ods file from LibreOffice using MS Office 2013 for Windows and it does open though with a warning that some things have been changed. I don't know if Office for Mac can normally open .ods files. But if your need is to just open .ods files, take a look at LibreOffice.

How can one read a Excel File and Upload into Table using Pl/SQL Code.

How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.

If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.

Error in reading from excel file

hi,
I have written a program which reads from excel file
and based on the value of the column i have to do something.
Everything is fine but when i run it, it produces an error message

                             }

Maybe 851.0 is float value, not string.
Try Object columnValue1 =
rs.getObject(i); instead of String
columnValue1 = rs.getString(i);
You are absolutely right i actually change the line
custNo =Integer.parseInt(columnValue1);
into
custNo =Double.parseDouble(columnValue1);
Thanks alot :)

Read an excel file using JSP in MII 12.1

Hi,
I want to read an excel file using jsp page. I dont want to use the UDS or ODBC for connecting to excel.
I am trying to use org.apache.poi to read the excel file in jsp page.
While running, its showing a compilation error "package org.apache.poi.hssf.usermodel does not exist"
I have the jar files for it, where do we need to upload it so that jsp page works.
Thanks a lot
Regards,
Neha Maheshwari

The user doesn't want to save the excel file in server.
I want to upload file and save its contents in database.
I have the code to read and save excel data in database but not able to get the location to deploy the jar file.
In general, if we are creating a jsp page in MII workbench which is using some jar file.
Whats the location to upload this jar file so that the jsp page works correctly?

It prints correctly the output at the console and after that it throws an exception as

Does your Excel file has the "AutoFilter" activated?
If that is the problem, you have here a solution for reading a file with AutoFilter : http://article.gmane.org/gmane.comp.jakarta.poi.user/4690

Hi,
You are trying to read file wrong way. In the tutorial of Java Excel Api: "JExcelApi can read an Excel spreadsheet from a file stored on the local filesystem or from some input stream.". You are trying to read from file system. So you must get file input stream then you can read it. Please search forums KM file read.

Store data in mysql after reading from excel files

i am trying to make o program where i will read the data from excel files and i will store them in a database. I am using eclipse as editor and mySQL. I am using APACHE POI to read the excel files and JDBC for the connection. The excel files have the structure as shown below:
ID NAME SALARY STREET
321 TIM 1254 14 avenue
121 PAUL 1265 28h oktovriou
432 NICK 4521 papaflessa
I have of course plenty of such files which contains many more rows and columns. The purpose of my program is to read the data, create table named as the name of the excel file and the fields of each table to be the first rows of the excel file. Afterwards the values will be the rest data of the excel file. In the code below i have managed to read them, show the data in the console. Afterwrds i am trying to call a database with JDBC but there i have problem when i create the table.
try
String[] allFields;
String createTableStr = "CREATE TABLE" + createTableStr
+ "(" + org.apache.commons.lang3.StringUtils.join(allFields,
",") + ")";
Could anyone help me?
Thank you in advance!:)
