OK, got somewhere on the multi-line entries.

This method may go horribly wrong if you have special characters such as ampersand, gt, lt etc since currently it's writing raw text.

Working on getting it to just do better carriage return character only but....

In WriteHeaderInfo //default styling add the second line of

xw.WriteAttributeString("ss", "Vertical", null, "Bottom");

xw.WriteAttributeString("ss", "WrapText", null, "1"); //added for multiline support

and in Data styling change the wrap:

xw.WriteAttributeString("ss", "WrapText", null, "1");

Then in the cell writing bit change as below:

//xw.WriteString(output);

xw.WriteRaw(output.Replace(Environment.NewLine, "& #xA;")); //remove the space between & and # of course.

I'm looking at overriding the settings.NewLineChars though so there is no need for the raw writing.

Edit: OK, setting.NewLineChars is just how it writes the newlines in the whole file, not those in the data so no good.

That method does not work on 64-bit SQLm the CLR method does

Which method does not work? You may need to be more specific or quote the post you were referring to since there are many pages worth.

The extension hardening got a little harder trying to name file with xlsx extension.

When I change C# source to have xlsx extension the Excel file will not open. Granted Office 2007 opens it fine with xls extension - I would still like to make it work with xlsx - anybody have any ideas on what needs to change in the C# source to make it happen - or is it something on the Office side.

Definitely an office side thing.

By specifying xlsx you are telling it it that it is definitely written in 2007 format which is the MS office XML format zipped. Since it has no zip header it won't open I assume.

Quite good actually, if you have somethign like 7zip you can extract the contents of any office2007 file to view the xml that's at the back end of it.

I just wanted to say thanks to the author for this article. It worked out of the box for me on a project I am doing for a process engineering firm.

I am not using the CLR approach, just using it from a web application that exports an equipment list of manufacturing plant components. Some of thse lists can be quite big and XML is kind of verbose, so I am going to have to try this with a big file.

I read SQLServerCentral.com newsletters all the time. I get a couple newsletters and these are the best.

Anyway, thanks for this article!

I'd like the dll itself as a direct download, don't have the tools here to compile the sourcecode myself 🙁

In the source download, the dll is in the folder \ExcelExport\bin\Release 😀

This is working fine for me when the filepath is to a local directory (C:\..), but when I try using a network location I get an error returned.

Msg 6522, Level 16, State 1, Procedure ExportToExcel, Line 0

A .NET Framework error occurred during execution of user-defined routine or aggregate "ExportToExcel":

System.UnauthorizedAccessException: Access to the path '\\project.co.uk\project\build\ExportTest.xls' is denied.

Where do I need to give permissions for this to work?

SQL Server is running the CLR... SQL Server must be runing as a user that has the privs to "see" the UNC.

I have tried this and it seems to work fine, however it does not recognise excel when I tried to open although it opens it and my main point is it does not work on a network drive, basically the file needs to be saved in the server where sql server is installed.

Any way to make this work on a network drive? I tried and have required permissions but not working.

Ideally I need it to run on a nework driver to avoid round trips to the server to retrieve the created file.

Thanks

I normally just create a very restriced access share on the DB machine so I can grab the files off it remotely. I find that with SQL server it's a great sanity saver to work with local drives within SQL and work out the access elswhere.

For this exact issue though when users needed access. I actually set the file location to the SQL server local folder that Reporting Services web site is hosted in.

I had a report that ran this SP as well as the same results in the web report and included a static hyperlink to the file.

Nice easy solution.

Basically the reason for this was that they wanted the report both pretty for sending on but still able to sort through in excel and any kind of prettyness messes up the exported file's ability to sort due to merged cells etc in RS.

I do this on several of my reports that I wrote this code for. As have been noted above, you should be able to do it with the account that SQL runs under's permission on the folder.

Another way I use it is part of SSIS packages, and then use the file copy in SSIS to put the file in it's final folder (I have some that for various reasons go to multiple locations).

Most of mine though are mailed out from SQL directly to the recipients.
