I'm really stuck tryign to figure this out. Converting XLS to CSV is no big deal or at least it seems that way. However, trying to go xlsx to csv seems to be more difficult. For grins, I grabbed some code that is supposed to read a sample xlsx file and convert that into a gridview called GridView1. I figure it can't be much different to turn that into CSV.

Want to create a web based application for reading and writing excel files.
Issue :
1. Want to upload an excel file and store it some location.
2. Read data from excel file, performing some sorting and filtering
3. Write filtered data to new excel file.
I am loading documents into our Oracle database and then retrieving them for the users to view. So far PDF, DOC, XLS, CSV, etc. all perform as expected, however; DOCX, XLSX, etc. files have one annoyingly persistent issue.
When the document is downloaded by the user and they open it you get the first in a series of messages:
The file 'thefile.docx' cannot be opened because there are problems with the contents.
Details: The file is corrupt and cannot be opened.
and then:
Word found unreadable content in 'thefile.docx'. Do you want to recover the contents of this document? If you trust the source, click Yes.
After clicking yes the file opens and all of the content appears correct. Including images, formatting, tracked changeds and comments, equations, etc.
I have tried multiple methods along these lines to no avail. I simply want the files to open without the false-positive error messages.
I am using VS2010, with the website targeted at .Net Framework 2.0.

The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?

I have a web application (ASP.NET 3.5) that allows the users to upload their own excel sheet. This sheet contains information about items that needs to be inserted to SQL Server 2005.
I already have this functionality, however, it's very slow (it takes almost 20 minutes to finish the request). I need a better way to handle this problem.
The sheet contains information about an item. These properties will be inserted into multiple tables for example (Books, Authors, Titles ... etc ...).
What I'm currently doing is the following:
The user uploads the file. The application opens the file. Read each row and update the database accordingly.
I'm using Microsoft.Office.Interop.Excel
Edit: I'm working with 10.000+ rows per sheet.
I've used the Import/Export wizard to get data into SQL from Excel and it works great. When I want to reverse the process, however, I can't. I've gone through the wizard multiple times and I've done what I think is everything to try to get the data out. What am I doing wrong?
View 10 RepliesI have an small ASP.NET application that reads data from a table and sends it out as an excel attachment in an email message. The data is simply HTML table tr td tagged data. The way I am sending the message is by the following code:

mm.Attachments.Add(new Attachment(memoryStream, "info.xls", "text/plain"));
This has been working fine in Excel 2003 but for some reason Excel 2007 keeps trying to convert the whole thing to a formula and I get a "Cell Data too Long" error. I've tried searching but couldn't really find anything specific about why this might be happening in 07 or a simple way to fix it. I know 07 probably handles data a little bit different than 03 but I don't have a lot of time to dedicate to reworking this app if possible.
When i export the data table to excel 2003 i get the output in a very fast manner and when i want to use the same in excel 2007 debugging gets stopped and nothing happens.... It does not show any errror on it to. When i slowly debugged i find that in saveas() it takes longer time and it seems like execution gets stopped in this process.
Its like in new window it shows loading for more than 10 min and after some time the particular window gets closed and nothing happens can anyone tell me what can be wrong.When the same code works great when i export to 2003.
