Could do with some more details on the data that you are actually trying to import.
The XML source reader is part of the standard packages.
And so is the excel destination
Meaning that in theory there isn't anything getting in your way. It's all about how complex your data can be. Especially because SSIS won't be doing any validation of its structure for you.
Also, bear in mind that exporting to excel can be a bit of a finicky process. Unless there is an specific requirement for this. I would recommend you to export to plain csv instead, which can also be opened in Excel and formatted prettily at a later stage.

This Question might be repeated, But I couldn't get solution regarding my problem so far. I'm new to Interop. I'm using excel file (as a database).
Here is data presentation in excel file
in my data If Card ID repeated then I need to increment '1' in Counter in the same row, similarly I need to fetch IP address of same row..
I'm using Interop Excel approach to insert data in excel file..
Kindly tell me how can I perform that update operation to that excel file through C# (WPF)
Sorry for bad English..
Thanks
I recommend using Closed XML
You write to the file directly and don't need Excel. It will need to be the latest version of an Excel file to work (The open xml standard).
Epplus.dll or npoi.dll will also read/write to excel files w/o excel.
Save the data in an XML or JSON file, then when you want to visualize them you create the excel file from these data, so you will have a very light file and easy to read and update if you wish.
I haven't done this specifically through wpf, but you can access powershell cmdlets through .net and powershell has commands for retrieving and writing Excel data.
That said, my experience has been it's very tedious and inconsistent with bugs. I would tell your client that using an Excel file as a database is impossible and certainly prone to failure in practice.
For one thing you will run into read/write restrictions if it is used by anything else.
If you don't mind to use comercial libraries, you can try to use Aspose.Cells. It has rich cells API and able to work without Excel interop API.
I need to make the information in the database usable by allowing the user to download it as a PDF or Excel spreadsheet (either one works, both is perfect).
I've looked around at a bunch of options, but I really can't decide which one I should use, let alone if any of those options are actually useful. Most of the options I've found revolve around converting already existing HTML files into PDFs which is not what I need. Also, it needs to be free. My bosses haven't given me a budget to spend on this
I'm not sure what other information I should include here.
Well, any help is greatly appreciated. If you have questions about missing information, I'll get it posted ASAP. I'm here all day, so I'll be able to respond to any comments very quickly.
EDIT: Oh wow! Huge thanks, guys, for the massive response! I got a ton of ideas. This is super-helpful. Thanks!
if you want to generate an Excel (or also a Word) you can use openXml. You can create a new document exactly the way you want from pure code.
OpenXml SDK page
The solution I usually propose to my clients in this situation is to use Sql Server Reporting Services (SSRS). You can use the ReportViewer control included with it in order to generate PDF's, Excel spreadsheets, XML files, CSV files, and others. If you need ad hoc reporting, there is a Report Builder available as well.
Barring that, you can use OpenXml to generate Excel spreadsheets and there are a host of PDF toolkits available.
Have you looked into the reportviewer control, which is part of Visual Studio?
It allows you to export the report in PDF or Excel format.

There are lots of reporting solutions out there such as SQL Server Reporting Services(for which you might already have a license). Take a look at Reporting (free || open source) Alternatives to Crystal Reports in Winforms which can likely be applied to the web with a bit of serialization.
I would suggest thinking about rolling your own depending on the situation. You could use pdfsharp for the pdf export and EPPlus for excel. They are both very easy to use and, I'm pretty sure, available in nuget with a couple of clicks.
If you want to go the Excel route, i'd recommend this article from Stephen Walther entitled ASP.NET MVC Tip #2 - Create a custom Action Result that returns Microsoft Excel Documents. This uses an old trick of writing an HTML document with an Excel mime type. This is different than streaming a native Excel file. And it's fairly easy to change the to rendering a CSV file if you want to strip it down, and make it a more universal file. Just remember to double-quote all the fields if there's a possibility of commas showing up.
If what your doing isn't too complicated you can use CSV files. CSV stands for comma separated values, and it is what it sounds like. You can create simple tables and columns using commas. For example paste the following lines into a text file:
heading1,heading2,heading3
info1,info2,info3
info1,info2,info3
Save the text file as a .csv file and voila - an excel spreadsheet. Obviously it is extremely easy to build these looping object collections. Mind you if you need any complicated text formatting etc then it is not really the best option.
I am interested in writing an application that will take in an excel document of a specific format, massage the data and create a new Excel document that has different formatting.
I am curious if anyone can recommend a good place to start on this.
My first thought was to write something my self in C#. I came across this tool on codeplex:
http://excelwrapperdotnet.codeplex.com/wikipage?title=Usage%20-%20Example&referringTitle=Documentation
But it appears to only be for Excel 2007.
Is there a best practice for doing this type of thing for Excel 2010 documents? Do I even need to program something custom to do this or does Excel offer something that might handle this?
Another nice library to modify Excel 2007/2010 documents (.xlsx) is EPPlus. It gives you a nice object model on your spreadsheets.
Excel files (.xslx) are archived XML files. They use 'Open XML', take a look here MICROSOFT Open XML
That should get you going on the right path.
I need to create a script that extracts some data from a complex Excel 2003 file (with multiple sheets and different tables inside a single sheet) and produces different XML files that need to be validated against a given XSD file.
My preferred language is Python;
to create and validate XML files i would go with lxml.
What do you suggest for parsing XLS files?
Is xlrd the right tool to use for complex Excel files?
Or do i need to convert all the sheets in CSV manually, and read files line by line, splitting and getting data?
I accept C#, VB6, VBA suggestions too.
[disclaimer: I'm the author of xlrd]
xlrd is quite suited for this kind of job. Get the latest version from PyPI. Get the flavour from the tutorial found here. XLSX support is in alpha test; e-mail me if you need it. The awkwardness and lossiness of the save-as-CSV approach was one of the things that prompted me to write xlrd.
Xlrd is OK. We use it extensively to import XLS files full of references and formulas with multiple sheets and data presented in custom (not Latin-1) encoding.
I am convinced the most simple solution for this task is using Excel VBA together with MSXML parser. Look here for some links how to use the MSXML parser in VBA for reading XML files; you can adopt this easily for writing XML files, I think.
I cant answer whether xlrd/python is the right tool for the job - as I don't know python well enough.
But there are many ways to access the excel data...in the main you have VBA built directly in to Excel.
Then you have Ado.net See David Hayden's article here which allows you to access the data via any DotNet language...even IronPython
I'm looking to generate some C# code based on Excel data. Basically the Excel sheet contains definitions of functions that need to be generated in C#.
My current experience with code generation is mainly with ORM's. But now the "input" is Excel data.
I'm asking this to prevent me from re-inventing the wheel. Reading data from Excel is easy, and generating C# also. But I'm a lazy programmer.
Is there a code generation tool that accepts Excel files as input?
You can use T4 templates. I know this too common/abstract answer, but this is the way, I think, and I don't think you can find something already exist for that purpose. Visual Studio 2008 has native supports for them. In your T4 template you can read excel file and then use its data to create any code file you want.
I am guessing you will have to hand roll this solution. This does seem a little wonky, would be curious how you got in a situation where you are needing to do code gen based on Excel?!?
Having worked with this problem before, I suggest that you convert the excel file to a CSV.
Im my case, I transformed the CSV file into C# classes (which include property and method definitions).
