I have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..

I seen some threads about export to Excel, but I tried all of it and nothing worked.I need to export the data on a DataGridView to an Excel (97 if it's possible or 2003 if not) sheet, using VB2010.
View 10 RepliesI've google so many examples but none of them work. Well they do but they don't perform the way I need it to:
1) Check if excel file with specific file name exists in application.startup path
2) If doesn't exist, then take DataGridView contents (including header names) and write it to a new excel file
If exists, then take DataGridView contents and append to the existing excel file (excluding header names)Can someone for the love of VB.NET paste some code that can do this? I've been at it for 3 days with no sleep and nothing has worked so far I make the smallest changes to code I find online and the bloody thing doesn't work anymore. I don't know why it does that...I already have Imports.Microsoft.Office referenced to my project so I can create Excel Applications on my form.

I'm exporting a datagridview to excel. The first column is a Date (not DateTime) which appears like '2/15/2011'. After exporting the datagridview to excel it appears in excel as '2/15/2011 0:00', furthermore the first 68 rows in excel appear as '6/14/1898 12:00:00 AM'. Where is the time coming from? The column type in the database is date. I've attempted to edit the cell style of the datagridview column to date. I've attempted to figure out how to pre-program the formatting in excel, but it's not working either.

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="/">

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.
