I am try to load multiple excel files into database, I have tried this link:
How to loop through Excel files and load them into a database using SSIS package?
but it keeps looping through the files and never ends.
can anyone help?
This is not likely given you have a small number of files which you should when testing.
You need to log the file names inside the ForLoop and see if the values are ever changing.
With the dynamic sheet name may have a stability problem, e.g. some characters may not be able to be picked up by the OLEDB driver.
This is in general a not recommended practice to process dynamic data.

Is it possible to insert a code so we can track all copied excel files in the future?
The reason why: we are creating a template excel file that people can copy and fill in. The problem is that they regularly have to fill in the same information so instead of starting from the template they copy the already filled in template.
If we decide to change the template, we want to change all the files that were copied so there are no multiple versions going around.
All the files are stored on a server in subfolders so We can access them all. Titles of the file will vary based on the wishes from the customer.
After reading you, I see that:
Summary:
You have one single Template that everybody copies
You store all the filled templates on one Server Subfolder
Title of the Files varies from Customer's needs
Challenges:
For Performance shake, you might need of a program than Excel to manage those files
Otherwise, it is possible to use Excel VBA, but is somehow/enough complicated so you would need to have an advanced skills and enough time to write everything handling that Subfolders' file renaming if you wish to collect the data in one Single Excel.
Suggested Solution:
I recommend you to have A Locked Worksheet + Workbook Excel
Template so your customers won't be able to edit its structure and
it will keep all of your templates to be the same.
You better have some kind of the Standard in the nomenclature of your Excel Files which will help you use that description later on for search/filter/sorting ...
You can have a Reset Button as well within the Template where your customers will click and will empty all the fields effortless.
In short, If you wish to track of files being copies, you would need more than Excel VBA for that as you need to play with A windows service for you to track them.
Hope this will give you some ideas. All the Best!
I am trying to combine (or perhaps append is a better term) a group (10) of identical column Excel files into one master file.
I have tried a very simple process using a foreach loop in the control flow and simply doing an Excel Source to an Excel Destination. The process was not only slow (about 1 record pasted per second) but the process died after about 50k records.
It looks like:
Foreach Loop Container --> Data Flow task
where the Data Flow Task is Excel Source --> Excel Destination
At the end, I'd want to see one master file with all files appended. I recognize there are other tools that can do this like PowerQuery directly in Excel, but I'm trying to better understand SSIS and I have a lot of processing that would be better done in SQL Server.
Is there a better way to do this? I searched high and low online but couldn't find an example of this in SSIS.
This is very simple. The one thing I would suggest is to load to a flat file in csv format that easily opens in Excel.
Foreach Loop enumerated on filename.
In Foreach GUI set:
The path of the Excel files
The structure of the file (ex myfiles*.xls)
Go to Variable mapping and map the fully qualified name to a variable
Create an Excel connection to any one of the files.
In excel connection properties open Expression and set filepath to the variable from 5
Also in properties set delay validation to true
Add a dataflow task to the foreach loop container
goto dataflow
Use source assistant to read excel source
use destination assistant to load to a flat file (may sure not to overwrite destination or you will only get the last workbook
I have to .xlsx files. One has data "source.xlsx" and one has macros "work.xlsm". I can load the data from "source.xlsx" into "work.xlsm" using Excel's built-in load or using Application.GetOpenFilename. However, I don't want all the data in the source.xlsx. I only want to select specific rows, the criteria for which will be determined at run time.
Thinks of this as a SELECT from a database with parameters. I need to do this to limit the time and processing of the data being processed by "work.xlsx".
Is there a way to do that?
I tried using parameterized query from Excel --> [Data] --> [From Other Sources] but when I did that, it complained about not finding a table (same with ODBC). This is because the source has no table defined, so it makes sense. But I am restricted from touching the source.
So, In short, I need to filter data before exporting it in the target sheet without touching the source file. I want to do this either interactively or via a VBA macro.
Note: I am using Excel 2003.
Any help or pointers will be appreciated. Thx.
I used a macro to convert the source file from .xlsx to .csv format and then loaded the csv formatted file using a loop that contained the desired filter during the load.
This approach may not be the best, nevertheless, no other suggestion was offered and this one works!
The other approach is to abandon the idea of pre-filtering and sacrifice the load time delay and perform the filtering and removal of un-wanted rows in the "work.xlsm" file. Performance and memory size are major factors in this case, assuming code complexity is not the issue.
I am currently generating the excel files dynamically using foreach loop+file system task+ data flow task which will load data to the excel files.
But, when i am getting duplicate records instead of over writing already created excel file. I want the duplicate records to load into already created file.
For example if for one product there are four prod items having same name. The file created with a specific product should have all the product items in it.
Please suggest me a solution.
Since this is excel generation which is most hectic thing in ssis.. please try to provide soln elaborately.
Thanks in advance.
Use a script task to see if the file exists. If it does, delete the file and regenerate.
Here are examples:

I have a two dimentional array formed by iterating a data reader. Earlier i was using automation to write to excel and using range, i was able to write the contents of two dimentional array to excel in one shot. This improves the performance a lot because of only one interaction with excel. but came across a problem that my server does not have office installed, so am trying a different alternative using openxml(as i justneed to install only one dll in this case).
Online i saw few example of using the openxml, but i am not sure if there is a way to directly transfter the contents of two dimentional array to the worksheet. i don't want to iterate the datareader and update each cell by cell as i have 65 columns and almost 90000 rows.
So does the SDK offer any inbuild command to do this?
you should't fear the iteration because there's no longer an "interaction with excel" dcom penalty. The open xml is just writing to a stream, which you can buffer to save flushing to disk.
fyi i've personally used closed xml (nuget # http://nuget.org/packages/ClosedXML ) to create Excel files and found it much better than working with the raw Open XML standard.
finally, even if you had excel on the server you should never use excel as a dcom server in a no UI environment.
