I need to create a SSIS Package which will run daily and export a table's data into a directory. The Exported excel have a predefined format. So I have used a template excel. (Excel File with Column Headers only)
Here are the steps I followed:
Created a variable Filename with holds the location and name of the excel to be generated
(based on current date value)
Added a File System Task in Control flow. Give Source as Template Excel and Destination as the Filename variable.
Added a Dataflow Task in control flow and connect it with File System Task.
In Dataflow Task, added a OLE-DB source and configure it with the source table (the table data needs to be copied into the excel )
Added a Excel Connection manager and changed Excel File path property to filename variable.
Added a Excel Destination and configure it with Excel Connection manager.
set Delayed validation true in Data flow task and Executed the package.
Control Flow:
Data Flow:
The Package is running successfully and the excel file also get generated in the desired directory. But the excel file skips around 19000 rows copying data after that . why it is happening?
Can any one help me to solve the issue.
Thanks for the help
It is possible that the file is already formatted , and that lines are down at the bottom...often excel jumps or add lines if you do not delete the lines already used even if empty...we must also consider strange events!

I tried to create a SSIS package to input excel file into database.
The excel file has dynamic name, and also i need to add filename into the database as well.
What I'm trying to do:
use for each file loop to set a variable called FileFound, with the value of
the filename (with full path)
set connection for the input file with above variable
use data load to load the excel to db, with above connection.
I got error saying the connection is invalid.

#Admin,
I tried to upload 2 images, and I got 2 image urls but they are not working.
can you please check?

There is step you missed when using dynamic file names in a foreach loop. You need to set delay validation property of the dynamic source (in your case the Excel Conn) to TRUE.
The package tries to validate in pre-execute phase unless you delay it.
I have created an SSIS project to load data from Excel file source. I am using foreach loop to take all Excel files from a selected folder. The loop seems to take the first file, but when it takes the next file an error occurs. It says that it needs a new metadata. The Excel source have the same file format and the same header (only one column data).
I am looking for an advice.
Sometimes excel will actually have more columns than it appears. Two ways to check this:
1. Save as csv and see if you have extra ,,, at the end of each line.
2. Create a quick test package and connect to the excel file and verify that the source has only one column.
I am setting up a For Each File Loop to upload all the text files in a folder and create a DB item with the same name. This however is causing me to get the above error. As you can see from the two screenshots below, I have (I think) set the Connection Manager for the OLE DB Destination object up correctly, but the error remains. Does anyone know why I am getting this and where I am supposed to specify a table name if a declared variable is being used for the looping?
In your variable definition (User::FileFound), you have to specify the sheet name in the Excel workbook you used to set up your Excel Connection Manager (e.g. 'Sheet1$').
You're presumably changing the value of the variable at some point in your For Each File loop process, which makes sense, but at design time, you have to specify a real sheet name.
In your Control Flow, click on your data Flow Component
On properties, change the 'DelayValidation' to 'True'
I have a very strange issue that I cannot seem to find an answer to online.
I have a VB.NET application that creates an Excel of data (roughly 42,542 rows in total) and the saves the file to a folder location & opens it on screen for the user.
The onscreen version & folder version is only showing 16,372 rows of data like it is being cut off.
When I go through debug I can see all the rows are being added & if I save manually in debug all the rows save. Some data seems to get lost on the system save.
I am taking data from 4 record sets & writing each set one after the other with specific headers for each block on the Excel sheet.
My save line is:
xlWBook.SaveAs(Filename:=sFileName, FileFormat:=Excel.XlFileFormat.xlExcel7)
Would anyone please have any ideas as to what this might be?
Older version of Excel only support 16,384 rows per worksheet. You are saving as Excel7 (which is Excel 95) and has this limitation:
See here for a summary of sizes per version:
https://superuser.com/questions/366468/what-is-the-maximum-allowed-rows-in-a-microsoft-excel-xls-or-xlsx
Change your code to another format, See here for all the allowed formats: XlFileFormat Enumeration
However the file format is actually an optional argument in the SaveAs method, so you could leave it off altogether: "For an existing file, the default format is the last file format specified; for a new file, the default is the format of the version of Excel being used."

As occurring more often something simple is not so simple in SSIS (v 2008)
Situation before B.I. came in: data was loaded into linked tables in hidden excel sheets, there were macro's and manual adaptations.
After: Still hidden sheets but we replaced macro functionalities with SSIS and had to unlink the table to get rid of the pop-up when opening the files: "The following data may have been lost: -Table"
Since we unlinked the table (and by consequence deleted the connection) we can't address the hidden sheet anymore via SSIS: Excel Destination. Non-hidden sheets are no problem and are visible.
--> Question: how can you export to a hidden excel sheet?
Since above action the sheet is not visible anymore in the Excel Destination windows, dropbox "name of the excel sheet".
Thanks in advance for any advice!!

The trick when the GUI doesn't let you do something in SSIS is to tell it you know what you are doing. ;)
In this case, the drop down does not allow you to select values from a hidden tab. The connection manager points to a Excel file with 2 tabs, Sheet1 and Hidden which is hidden.
It does however allow you to select "Table name or view name from variable" or "SQL Command." This solution will use the variable approach but command should work just as well.
As you can see, I have defined a variables called SheetName and assigned it a value of Hidden$
