Extracting data from Microsoft Excel spreadsheet

Hi,
I am currently developing an application that requires to extract data from Microsoft Excel spreadsheet. Is that possible to archieve it?
If it is possible,your precious guidience will be much appreciated.
Thank you.

There are several approaches.
1) Export the data from the Excell in "CSV" format, which is simple enough to read as an ordinary text file.
2) Use the open source POI package, which reads and writes XSL files (amongst other popular formats).
3) Use the JDBC/ODBC bridge and the Windows ODBC driver which allows and Excell file to be treated as a database. (More details in above reference).
4) Use another open source package to connect to Excell via the COM+ interface, and access data therein.
Personally I favour the POI package.

Reading data from an excel file

Hi,
I want to read data from the excel file and display it in
jsp page. Iam getting the following error:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =
DriverManager.getConnection("jdbc:odbc:mydsn","","");
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select * from [holidays$]");
Here i have created the dsn with the name "mydsn". I have the
following data in the mydsn.dsn file:
[ODBC]
DRIVER=Microsoft Excel Driver (*.xls)
UID=admin
UserCommitSync=Yes
Threads=3
SafeTransactions=0
ReadOnly=1
PageTimeout=5
MaxScanRows=8
MaxBufferSize=2048
FIL=excel 8.0
DriverId=790
DefaultDir=D:\WorkSpace\Projects\VINET\devl\webroot\jsp
DBQ=D:\WorkSpace\Projects\VINET\devl\webroot\jsp\list_of_holidays_2003.xls
thanks in advance
phani.

You might want to look at the POI project (an open source Jakarta sub-project) that allows you to create/modify/read excel files via Java code. That might be more flexible and easier than what you're currently trying to do.

GUI_UPLOAD to read data from an Excel File

Hi Folks,
I'm using FM GUI_UPLOAD to read data from an Excel File. But all I see in the table returned is 1 row with garbage values (special chacaters). Excel Workbook has proper data in the sheet, but its not getting uploaded properly. Sy-subrc is 0.
What could be the reason?
Thanks

Reading data froma an excel

Hi all,
           I want to read data froma an excel sheet.
The code i used to read the data is
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(IPrivateFileUplaodView.IContextElement.FILE_RESOURCE);
*     IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) attributeInfo.getModifiableSimpleType();*
*                    IContextElement element = wdContext.currentContextElement();*
*                    if(element.getFileResource()!= null)*
*                      try*
*                            String mimeType = binary.getMimeType().getFileExtension();*
*                            wdComponentAPI.getMessageManager().reportSuccess("File " + binaryType.getFileName() + " has been successfuly uploaded ! ");*
*                      catch(Exception e)*
*                            throw new WDRuntimeException(e);*
*                    else*
*                         wdComponentAPI.getMessageManager().reportException("File could not be uploaded", true);*
*                    // Till here the code remains the same as in File Upload tutorials*
*                    // Now the code for retrieving the values from the Excel sheet*
*                    try*
*                       ByteArrayInputStream bais = new ByteArrayInputStream(element.getFileResource());*
*                       Workbook workbook = Workbook.getWorkbook(bais);*
*                       Sheet sheet = workbook.getSheet(0);*
*                       Cell a1 = sheet.getCell(0,0);*
*                       Cell a2 = sheet.getCell(0,1);*
*                       wdComponentAPI.getMessageManager().reportSuccess("Value of cell a1 = " + a1.getContents());*

*                    catch(Exception ex)*
*                      wdComponentAPI.getMessageManager().reportException(ex.getLocalizedMessage(),true);*
But i am getting error at "binary" in String mimeType = binary.getMimeType().getFileExtension();
and ByteArrayInputStream bais = new ByteArrayInputStream(element.getFileResource()); by saying that there is no constructor of
ByteArrayInputStream with Resource as parameter.
Please let me know what might be the issue so that i can solve this.
Thanks and regards,
Chandrashekar.

Hi,
Replace the following code
ByteArrayInputStream bais = new ByteArrayInputStream(element.getFileResource());*
with
IWDResource resource = element.getFileResource();
       InputStream inputStream = resource.read(false);
       ByteArrayInputStream bais = new ByteArrayInputStream(inputStream);

Problem reading data from oracle database 11g using OleDbDataReader

Hi everyone I work with Visual Studio 2010 and C# programming language. I have a problem reading data from the oracle database. I created a WPF application with my main Window Xaml and class files and 1 more class called DataFiles. The thing I want is to read some data from the database on my grid in my WPF window. Problem is even though it connects to the database the grid is always empty. It isn't the connection string as I tested it and it connects to the database the problem seems to be in showing the LASTNAME (PREZIME in my native tongue) on the grid which is what it's supposed to do.
Here is the code:
Data Files Code
using System;
using System.Collections.ObjectModel;
using System.Data.SqlClient;
using System.Data.OleDb;
namespace SQLKonekcija
    public class clsEmployee
        public string Prezime { get; set; }
    public class DataAccess
        OleDbConnection oleCon;
        OleDbCommand oleComd;
        public DataAccess()
            string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****;";
            oleCon = new OleDbConnection(connectionString);
        public ObservableCollection<clsEmployee> GetAllEmployee()
            ObservableCollection<clsEmployee> EmpCol = new ObservableCollection<clsEmployee>();
            oleComd = new OleDbCommand();
            oleComd.Connection = oleCon;
            oleComd.CommandText = "Select PREZIME from UPOSLENICI";
            oleCon.Open();
            OleDbDataReader Reader = oleComd.ExecuteReader();
            Reader.Read();
            while (Reader.Read())
                EmpCol.Add(new clsEmployee()
                    Prezime = Reader["PREZIME"].ToString()
            oleCon.Close();
            return EmpCol;
        }And here is my main window.cs code
public partial class MainWindow : Window
        clsEmployee objEmpToAdd;
        DataAccess objDs;
        public MainWindow()
            InitializeComponent();
        private void Window_Loaded(object sender, RoutedEventArgs e)
            objDs = new DataAccess();
            dgEmp.ItemsSource = objDs.GetAllEmployee();And the XAML
<Window x:Class="SQLKonekcija.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
    <Grid>
        <DataGrid AutoGenerateColumns="False" Height="237"
                  HorizontalAlignment="Left" Margin="18,66,0,0" Name="dgEmp"
                  VerticalAlignment="Top" Width="466" ColumnWidth="*"
                   >
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding PREZIME}" Header="Prezime"></DataGridTextColumn>
            </DataGrid.Columns>
        </DataGrid>
        <TextBlock Height="42" HorizontalAlignment="Left" Margin="18,15,0,0" Name="textBlock1" Text="TEST CONNECTION" VerticalAlignment="Top" Width="462" TextAlignment="Center" FontSize="28" FontWeight="ExtraBold" />
    </Grid>
</Window>
The guys on the MSDN forums told me I should ask the question here so sorry if it's not your field.
Hope u guys can help, thanks.

I tried it, commented out the reader.read and have the following connection string
string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****; OLEDB.NET=True"
Unfortunately the result is the same.

JavaConsole Error: Problem reading data from server

HI All
We are getting this error on java console on a page:
Error: Problem reading data from Server - Java.Security.AccessControlException:access denied (java.util.PropertyPermission http.strictpostredirect Read)
In this page we are not firing a SQL Query of huge data.
Any suggestions on this why it is happening?
Thanks
Manisha

Manisha,
I think JVM(Java Virtual Machine) is trying to access something at network level and it cant able to find it.Or any new patches of java is installed.
Or may be due to IIS or Applet,Don't know exactly.

Problem reading data from two tables

Hi experts,
I'm developing a JDBC - IDOC scenario that needs to read data from two oracle tables. I have created a BPM that has a initial fork for the two channels and it works fine.
The problem is that I need to read data from the first, two or both tables depending if there is data to read. If there is data in the two tables it works, but if only there is data in one of the two tables, I have read problems. I have tryed to set the 'neccesary branches' to 1 but this is a problem when I have data in both tables.
Any idea?
Best Regards,
Alfredo Lagunar.

Hi,
have your fork step inside a block and then right-click your block to insert a deadline branch to your BPM process and specify the time after which your BPM process should be cancelled.....so if in that time, you get data from both tables, your BPM will work okay otherwise if that time is over, then your BPM process will be cancelled.

If you are using LabVIEW 2014, it includes the Report Generation Toolkit (which is also available as an add-on in earlier LabVIEW Versions). This can read native Excel files, including .xlsx. With a few functions (3 or 4, I think), you should be able to get the entire Table into a 2D array.

Is it possible to create a form that allows users to import data from an excel spreadsheet

I have not been able to start my reading on scripting or other livecycle features to be able to try to figure this out but I was wondering if anyone else had ever created a form with this feature or had any ideas of how it would be possible. Our company currently uses and excel form that would have a variable number of rows of data for each time it is filled out and we would be replacing it with an adobe form. I would like to know if the users, who will be using the new adobe form in adobe reader, could have the capability to imort the lines from the previous excel form into the new adobe version.

Hi,
You can set up a data connection with an Excel spreadsheet. However for the data connection to work for users with Reader, you would need to Reader Enable the form with the LiveCycle Reader Extensions ES2.5 (server component). See here for summary: http://assure.ly/etkFNU.
However if you are just trying to get the existing data into the form, you should have a look at some of Stefan Cameron's posts: http://forms.stefcameron.com/ (try a search). You can start a new form using the wizzard and select import from Excel. This will allow you to paste from your spreadsheet to a new form. This should help set up the data structure/schema, which you can then replicate in a new form. I haven't done this before, but it should be possible.
Hope that helps,

Hi smercurio_fc
Hi Smercurio_fc,
Thanks for the reply. I really appreciate your help.
However, I would like to point out that after making numerous searches, I could not get any VI or thread working for my case. Most of the files complain regarding any of their missing sub-VI(s).
I myself don't understand the problem. I have even re-installed the application to shoot any of the possible installation errors. I m not a spammer.
I'll try to do what you have suggested in the former part of your reply.
Regards,
RJ

How to read data from many excel files

I'm aquiring data continusly from several sensors, and every days file name are changed. Data are saved on xls files.
Now, I'd like to read every data from this files and put them in a waveform. How can I concatenate all files and read the values?

You probably do not want to use a traditional waveform. LabVIEW has a Waveform Chart which inputs one point at a time. Waveform Graph inputs an array.
I suspect that the data is stored in an array. You need to read the arrays in and build them into larger arrays. If your right click on the build array vi, you can select concantenate which will append one array to the end of the other. When you have built your giant array, just feed it to a waveform graph.
If you need to see some example code, go to the advanced search page. It is at www.ni.com >> support >> advanced search (it is at the botton--click on the words). Enter excel read in the all the words field and search just the example programs. There were for hits.
