C# - How To Export Excel Worksheets Into New Workbooks
May 8, 2009
I have a bunch of Excel workbooks that contain multiple worksheets. I want to loop through each workbook and export each worksheet into it's own new workbook. I want one worksheet in each new workbook.
Here's what I've got so far:
Sub ExportWorksheet(ByVal worksheet As Excel.Worksheet, ByVal filePath As String)
Dim xlApp As Excel.Application = New Excel.ApplicationClass
Dim xlWorkBook As Excel.Workbook = xlApp.Workbooks.Add
worksheet.Select()
worksheet.Copy()
[Code] .....

In VB 2008, I am trying to create an app that will copy a range of cells from one worksheet ("xlWS1") in the first workbook ("xlWB1") to another worksheet ("2") in a second workbook ("xlWB2"), starting in cell A1. I would like this to be activated by a button.Then, another button will copy the same cells from "xlWS1" to "xlWB2", worksheet "3", and so on for each subsequent button.
xlWB1/xlWS1 contains data in the cells that is updated from our data acquisition system once per second. (we perform jet engine testing). "xlWB2" sheets (6 of them) will contain the saved data from the "live" screen (xlWS1, came cell range) in the first WB. There are several different versions (filenames) of the second workbook, one for each engine model.Both workbooks should already be open, but I would also like the app to open them if they are not open already.
We have been using VBA macros to do this, but run into problems when someone saves the second (destination) workbook under a different filename. For some reason, if the filename of the Wb that is already open isn't the same as what's in the macro for that button, the macro's defined workbook is renamed in the macro. I am trying to get away from using the macros to keep this from happening, and to make an app that's "foolproof" so it is more reliable.
I already have an app that will open the proper workbooks. I may combine the two apps in the future. I can't find a solution for this. The VBA code is quite different and simple as far as opening, activating, copying, etc. Basically, I can't seem to find any self-explanatory "activate/copy/paste, etc." namespace in Vb 2008 like I used in the VBA macros.
I'm sure the solution is simple, but I just can't seem to find it in the MSDN library or the VS 2008 book I have. Everything in the book talks about accessing databases, which we don't use (yet). There's nothing concerning this issue with Excel 2003 workbooks/worksheets.

I have 2 workbooks( Book1 and Book2) with multiple sheets.I am only interested in one of the worksheets in the workbooks(both the worksheets names are the same).The thing is that the data is in the form of pivot tables, so each time i have to filter according to specific categories, copy and paste into another new workbook.The thing is column headings in both the worksheets are different,BUT BOTH the worksheets data must be combined into 1 single worksheet( row after row).
Meaning in Book1, my columns are in the form of Cost, revenue,margin and in book2, the columns are in the form of Cost,Revenue, Profit Margin %.... That means i must add a profit margin % column in Book1 and a Margin column in Book2 before I combine the data into a single worksheet. Each week, new data gets added into Book1 and Book2, so I wish to automate this by creating a code, so that when the source data changes, my new workbook's data also changes.

So i am trying to add new worksheets to excel...not a problem there, but then I had a thought: What I really need is the proper code to add new worksheets on open that are named all of the dates in the current month minus saturday and sunday dates. That is what started to throw me for a loop. so i started with
set
newsheet = worksheets.add
newsheet.name = date

Trying to get names of all visible open excel workbooks. I found code online, that is below.I suspect the code is not working for me because either: I didn't include a reference (in addition to the MS Excel 12.0 Object reference and in addition to the Microsoft Office Interop reference, both were made) or something else basic being missed. i have been using the "early-bound" code below that is recognizing oExcelApp as visible...however, the open excel workbooks that I have open, are not being recognized.
I am using Windows XP and VB in Visual Studio 2010.Here is what I found online; disregard the late-bound if doesn't apply:

Our small business uses a VB project to 'process' information in excel workbooks. The project works on all machines except one (a new one) which generates a "Runtime Error 9". All machines are using Office 2003. When I try to debug it takes me to the following code, Workbooks(Tempname).Close SaveChanges:=False

I'm trying to generate Office 2010 files (xlsx) in a vb.net project (Visual Studio 2010 fw 4.0).On my developing PC it works. Once on the server it generates an error:Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).On the server I tried with dcomcnfg and navigate to DCOM Config and locate Excel. To solve the problem I would have chosen Customize in the Security tab under Launch and Activation Permissions and add the account under which the site is running (our server task user) and assign Local Launch & Local Activation permissions.[code]

I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
the stored procedure outputs XML and it is transformed by XSLT before it is displayed on EXCEL
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<HTML>
[code]....
adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?

I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

I need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:

But I do not know which one is better for my needs. I need to export not only grid row data but also Chart (image), thats why I am thinking about.

Using VB to open a .csv file with "excel.workbooks.open", editing it, then saving as .csv.
Even though it is saved as .csv, it is still identified as .xls.
Is there an alternate way to open this .csv file so that when it is saved as .csv the excel application actually identifies it as a comma delimited, not a spreadsheet?

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

We use a small bit of excel exporting code in our app code at work to export XML controls from our ASP pages into an excel format using the following code:
Public Shared Sub Export(ByRef xml As Xml, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response()
response.Clear()
[code]....
This is all fine, except we've encountered a rather frustrating bug. If the XML control has a link in it then the export code is called again. We have a button which will say "Export to Excel" from the .aspx page which simply calls ExcelExport.Export(Xml1, "MyFileName") which is in a LinkButton click event.Here's the order of events based on the form submit (selecting filters)
Enter filters
Submit form
Page_Load occurs
[code]....
So the user submits a form which loads up the XML control in a nice viewable XSLT page. Then they click "export to excel" which will give them the page in excel instead, then they click on the XSLT page, for example a link, but the save dialog for excel comes up again. We've gone through the series of events, and if we do not call the excel exporter it goes through the series of events as normal. If we do call the excel exporter it will go through the page load event and unexpectedly go into the link button click event.
