How to read the excel file using webdynpro abap?

Hi,
how to read and modify excel file using webdynpro abap?
Regards,
Pavani

For reading excel file follow the steps :
1. Use a File upload UI element and bind it with xstring.
2. Now your excel will be uploaded and stored in Xstring.
3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
4. Now split the string at new line so as to make an internal table .
Ex . SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE it_table.
here it_table is type table of string.
5.now loop at the internal table and separate the content of this table separated by tab.
Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
it_new type string_table.
6. For more info , refer this thread :

Error reading excel file using POI.

Hi ,
I am having some problem when reading the excel file.
While reading excel file I am getting error-java.io.IOException: Unable to read entire block; 4 bytes read; expected 512 bytes.
part of my code:-
InputStream stream = objFormFile.getInputStream();
POIFSFileSystem fs = new POIFSFileSystem(stream);//getting above error here.
HSSFWorkbook wb = new HSSFWorkbook(fs);
Case 1:
I download the file on the system ,save it ,and then directly upload it to the system ,I get the above error .
Case 2:
It works fine if I download the excel and manually open and save it and then upload it .
I am using JDK1.4.1 and poi-2.5.1-final-20040804.jar.
Can any one please help me out for the above problem?
Edited by: hruday on Jul 31, 2008 3:20 AM

Instead of using POIFSFileSystem, try to directly create the HSSFWorkbook
InputStream stream = objFormFile.getInputStream();
//POIFSFileSystem fs = new POIFSFileSystem( stream );//getting above error here.
HSSFWorkbook wb = new HSSFWorkbook( stream );

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.

Uses the library to get UTL_FILE to read a excel file in PL SQL?

Good day.
Someone can give me some code that uses the library to get UTL_FILE to read a excel file in PL SQL?
I intend to use this library because I want to run a script on my machine to treat an excel file without having to make changes on the server.
Thank you.

Thank you.
Ranit's links are useful, you should read them.
Also check out the FAQ on this forum:Re: 5. How do I read or write an Excel file?
UTL_FILE is not the best choice for reading data from Excel files.
It also will not be able to read an Excel file located on your client computer. As with any PL/SQL code on the database, it can only access things that the server itself can see, so that doesn't include hacking across the network, bypassing network security, and hacking into the client computers operating system to read files directly from it's hard disk. This isn't how client server architecture is intended to work.

Reading heavy excel files page wise using OpenXML

Hi,
I am using OpenXML to read heavy excel files, but I am using paging to read files because I have to process data and show in Grid on frontend.
Problem here is for reading every page of 10000 records its time is increasing.
First Page = 38397 Milliseconds
Second Page = 81910 MS
Third page =117923 MS
Fourth page =150142 MS
Any body has any clue...

Hi,
>> I am using paging to read files <<
Are you sure the extra time is used to read the data from Excel files or
show the data in Grid? If not, I suggest you checking that.
If the issue is related to reading data from Excel files by Open XML SDK, would you mind sharing some sample code for us to know how you read the files and troubleshoot?
If the extra time is used for showing data, I suggest you posting in the proper forum based on your developing language for more effective responses.
