Excellent Dll. The performance is very good.

Simple to use, but incredibly slow with larger data sets.
Downloading some 5000+ rows from our DB and writing to an Excel file spiked the CPU on all 4 cores on the test machine...
If your application requires using large data, use this library

Is there a way to recover the corrupted .xlsx file which is created with excelpackage?

Works but slow while writing large files. I've started a new project on codeplex for writing excel which is fast and light weight. You can find it at https://openxmlpackaging.codeplex.com/.

GPL make me not to use this (:

It's working for reading and writing. but it's dead slow.
I tested writing 1000 rows with 5columns. Means 5000 Cells.
I tool 11.7455057 seconds. To write big files, it's taking hours.
So I personally may not suggest for real time where you would need to handle huge files.

I tried this, but it didn't work for me, so in the end, I wrote my own open-source version.

Works great, but unusable for me because of GPL. What's the point of a .NET GPL library?

Any one knows how to export HTML content to .XLSX file using Office Open XML ?

This works perfectly to me, but GPL is out of question.
There is no sense in build a .NET component under GPL dude.
Maybe if work with perl or ruby...

Looking good ... but I am not sure what was made impossible by the fact it is GPL?
on Sep 16, 2011 at 2:28 AM
Very Good Library, but us would be much better served where it LGPL
on Aug 10, 2011 at 12:49 PM
Unusable due to GPL.. Is it a study/reference API/application?
on May 11, 2011 at 4:11 PM
Very good ! Viva GPL !
on Jan 20, 2011 at 2:51 PM
Great lib... But GPL makes it unusable
on Oct 8, 2010 at 4:30 PM
Just to clarify the comments on GPL; You are totally allowed to freely use the code as you please. But, IF you supply a public release of your project, THEN you must include the source code (or at least make it accessible).

Thank ou very much, i was looking for this long ago
on Jul 12, 2010 at 12:35 PM
Overall it's a useful utility, though working with styles is not very intuitive.
However, the GPL license makes it totally unusable at my company. Wouldn't be an issue if it was LGPL. For people who don't know: GPL license means to legally use this, your software which uses this library must be released as GPL-licensed open source software.

Finally, a GPL'd xlsx writer :)
on Jun 7, 2010 at 1:49 PM
This is currently buggy and it needs a little work. check out EPPlus which is built upon this with added features and its still maintained.

Sounds promising, but yes, GPL impossible.
on Feb 4, 2010 at 10:58 AM
Sounds like a good product, but the GPL license makes it unusable. Change the license please.
on Jan 21, 2010 at 6:34 PM
but seems to have been abandoned. there are a few critical bugs. i wish someone would pick up the reins again
on Jan 12, 2010 at 7:34 AM
Could you update the license to LGPL. It's a nice library, but it cannot be used in commercial environments. With the LGPL license commercial application can use the library, while changes to the library itself must be made public..

hello, why support only 2 sheets?
i can't write cell value in sheet after 3 number.
on Nov 17, 2009 at 10:49 AM
Fantastic piece of example code... been fighting with this for days.
on Sep 22, 2009 at 12:33 PM
As a suggestion you could change
DirectoryInfo outputDir = new DirectoryInfo(@"D:\ExcelPackageSamples\");
DirectoryInfo outputDir = new DirectoryInfo(System.Environment.CurrentDirectory.Substring(0, System.Environment.CurrentDirectory.Length - 9));
in the ExcelPackageSamples Main

Magnific piece of software.
Congratulations to Dr. JohnTunnicliffe and anandbisht.
I'll write a review on my blog as soon as I have the time.

Good stuff, GPL makes it un-usable.
on May 5, 2009 at 7:25 PM
Nice library, though the GPL license is very disappointing.
on Mar 19, 2009 at 11:41 AM
I've been programming (foolishly) alot of Excel VBA. There is now no need to ever delve into that intolerable IDE. This library exposes the worksheet in a very similar fashion, making it intuitive to use. Thinking of writing your own report printer? You won't be after you use this library!
on Feb 10, 2009 at 6:45 AM
Good stuff, but very bad performance when dealing with big XLS files. Writing to disk --> slow, Memory increases until the OutOfMemory exception is thrown. Ideal for small XLS files...
on Oct 2, 2008 at 12:44 PM
Beautiful, this is a great project for a very average programmes who is struggling for budget an still want the bestt quality to offer
on Sep 27, 2008 at 5:00 PM
Excelent for treating Excel-info in a ".NET-way"
on Sep 22, 2008 at 9:59 AM
Fantastic product. It makes creating the new excel file format files very easy. Pitty it has not been updated and expanded for some time.
on Sep 1, 2008 at 11:37 AM
I am astounded that this has no other reviews! I think it is great! An initial release that does what it is supposed to. This is a useful application as it came out and the input from developers has made it better, yet.

Opera does not support ClickOnce X
To install this application, save it and then open it. Opening it directly from Opera will not work correctly.
