Reading second sheet of excel file while uploading
Hello Freinds,
I want to read second sheet of an excel file while taking the data from excel file into an internal table.
Kindly help me with a FM which would take the sheet number too with the input OR a suitable option.
Hi ,
Try these links:

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. -

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?

Reading long text from excel file to an internal table
Hi
Can any body tell me how to read long text from excel file to an internal table.
When i am using this FM KCD_EXCEL_OLE_TO_INT_CONVERT then it is reading only 32 characters from each cell.
But in my excel sheet in one of the cell has very long text which i need to upload into a internal table.
may i know which FM or what logic i need to use for this problem.
RegardsHi,
Here is an example program. It will upload an Excel file with two columns. You could also assign the Excel structure dynamically, but I wanted to keep the example simple. The main point is that the internal table (it_excel in this example) must match the Excel structure that you want to convert.
Remember, this is just an example to help you figure out how to properly use the technique. It will certainly need to be modified to fit your requirements, and as always there may be a better way to get the Excel converted... this is just one possibility that has worked for me in the past.

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.

Manipulating excel file while using GUI_DOWNLOAD
hi all,
while using GUI_UPLOAD i want to
1) fix the width of the column of excel file
2) define the font of the data in excel file
3) change background color of the cells in excel file.
please suggest as to how can this be done?using GUI_DOWNLOAD you can't change the data in excel sheet...if you want to do the things you need to use OLE concpets for downloading of data to Excel sheet wherein you can do most of the options excel can handle..
Check within SDN as there are blogs for downloading data to Excel sheet using OLE concepts.. -
How to create new Sheet in Excel file and write into it
Hi to all, my requirement is this:
I have an excel file (.xls) with multiple sheets (three sheets for precision: sheet1, sheet2 and sheet3).
I must create in the same excel file new sheet, say sheet4, read data from sheet1, sheet2 and sheet3 and write them into sheet4.
How to realize this in SSIS?
Expecially, Is it possible to realize this in SSIS?
thanks in advance.You need to create the sheet with the required metadata. There's no use creating blank sheet.
Also metadata has to be fixed using a sample sheet prior to start of the package for setting the mapping. You may create a excel template for this purpose to just set the mapping at design time.
At runtime pass actual excel sheet path for ExcelFilePath property of the source to point to correct file.
Also the create table statement should include the same metadata info (columns)
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs
Hi, well it works fine! I have used a sample sheet prior to start of the package for setting the mapping.
Next at run time pass actual excel sheet path for ExcelFilePath property of the source to point to correct file.
However I have set also ValidateExternalMetadata properties of the Excel Destination to false and DelayValidation properties of the package to true.
Now my problem is the following:
I stored the three sheets name (sheet1, sheet2, sheet3) in the Object type user variable through a script task and the foreach loop loops through the three sheets stored in the variable.
Now, I want that at each iteration the CURRENT VALUE of the Object type user variable is mapped into another user variable wich in turn is given in input to the Excel Source.
Resuming:
-) I have to copy the content of three sheets (sheet1, sheet2, sheet3) of excel file into another new sheet, sheet4.
-) I stored the three sheets name (sheet1, sheet2, sheet3) in the Object type user variable.
-) With a foreach loop container I loops the three sheets stored in the Object type user variable.
-) Within a foreach loop container I have a Data Flow Task that transfer data from source sheet (sheet1, sheet2, sheet3) into destination sheet, sheet4.
-) PROBLEM: how to change dinamically at each iteration of the foreach loop the name of source sheet? In the destination excel Task the sheet is always the same at each iteration, sheet4. But in the source excel task the name of sheet musts change at each
iteration. In particular at the first iteration the name of the source sheet must be "sheet1$", at the second iteration "sheet2$", in the last iteration "sheet3$".
How to change sheet name dinamically at each iteration?
thanks. -

Read very very large excel file into 2d array (strings or varient)
Hi all,
Long time user, first time poster on these boards.
Looking at the copius amounts of great info related to reading Excel data from .xls files into labview, i've found that every one i've found from various people use the ActiveX method (WorkSheet.Range) which two strings are passed, namely excel's LetterNumber format to specify start and end.
However, this function does not work when trying to query huge amounts of information. The error returned is "Type Mismatch, -2147352571" I have a very large excel sheet i need to read data from and then close the excel file (original file remains unchanged). However this file is gigantic (don't ask me, I didn't make it and I can't convince them to use something more appropriate) with over 165 columns at 1000 rows of data.I can read a large number of columns, but only a handful of rows, or vice versa.
Aside from creating a loop to open and close the excel file over and
over reading pieces of it at a time, is there a better way to read more
data using ActiveX? Attached is code uploaded by others (with very minor modification) as an example.
Thanks,

Excel Get Data Specified Field (1-46col).vi 23 KBHi Maddox731,
I've only had a very quick glance through your thread, and I must admit I haven't really thought it through properly yet. Sounds like you've come up with your own solution anyway. That said I thought I'd take a bit of a scatter gun approach and attach some stuff for you regradless. Please forgive my bluntness.
You'll find my ActiveX Excel worksheet reader, which may or may not contain the problem you've come across. I've never tried it with the data size you are dealing with, so no promises. I've also attached my ADO/SQL approach to the problem. This was something I moved onto when I realised the limitations of AX. One thing I have noticed is that ADO/SQL is much faster than AX, so there may be some gains for you there with large data sets if you can implement it.
I should add that I'm a novice to all this and my efforts are down to bits I've gleamed from MSDN and others' LV examples. I hope it's of some use, if only to spark discussion. Your ctiticism is more than welcome, good or bad.
Regards.
