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 want to load the data from an EXCEL 2007 file to SQL Server 2008 database. I am geting following error.
The Microsoft Office Access database engine could not find the object 'Sheet1$'. Make sure the object exists and that you spell its name and the path name correctly.
Following is the complete source code. Kindly any senior member guide me what is the problem in the following code.
I have a scenario where I have to read an excel file to dump records in a mysql database. The code generates an exception Sheet1 not found. I have pasted the code below. Please let me know the solution to the exception. I have given the correct read/write/modify settings to my excel file.
if (fileUpload1.PostedFile.FileName.EndsWith(".xls") || fileUpload1.PostedFile.FileName.EndsWith(".XLS")) { string fileName = Server.MapPath(fileUpload1.PostedFile.FileName); string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=Excel 8.0"; // Create the connection object OleDbConnection oledbConn = new OleDbConnection(connString); try { // Open connection oledbConn.Open(); // Create OleDbCommand object and select data from worksheet Sheet1 OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]" , oledbConn); // Create new OleDbDataAdapter OleDbDataAdapter oleda = new OleDbDataAdapter(); oleda.SelectCommand = cmd; // Create a DataSet which will hold the data extracted from the worksheet. DataSet ds = new DataSet(); // Fill the DataSet from the data extracted from the worksheet. oleda.Fill(ds, "RestaurantExcelData"); for (int i = 0; i < ds.Tables[0].Rows.Count; i++) { Response.Write("Data: " + ds.Tables[0].Rows[i].ItemArray[0].ToString() + ""); } } catch(Exception e1) { } finally { // Close connection oledbConn.Close(); } } else { Response.Write("File Not Excel (xls||XLS)"); }
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.
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.
objConn = New OracleConnection(gstrConnectionString) objConn.Open()

I have some code that reads records from an excel file and then imports that data into an sql database. The issue only happens when the excel file has more then 350 rows in it. In the middle of the import it just stops executing and I get directed to the 'Internet Explorer cannot display the webpage' page or just a blank page when using firefox.
I dont get any time out errors or any error at all but still I tried messing around with the script timeout settings but still does the same thing at about the 2 min 30 sec mark.
I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.
[Code]....
Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.
I understand how to use a connection string object to read excel sheets. What I don't know is how to follow a hyperlink inside excel, grab matching data from the linked page and return it to my database. Essentially, the spreadsheet has two columns:
Title | Class#
Class# has the hyperlink which links to an internal web site. The connected page has a course description and any pre-required classes that must be taken before you can take this class. This is where I'm rather stumped as I've not had to do this type of thing before.
in my application i have to read from an excel files and check the value of every cell i'm using an OleDb connection to open it and reading but i have this issue if some of the cells in the excel sheet is having this warning when i try to read it returns DBNull ??could any one give me a clue ....knowing that i can not force the user for not having this warning ...i have to solve this within my code .
My web app is allowing the user to load a column of data from an Excel spreadsheet. For whatever reason, as it parses the data, fields that are just integers are coming up as System.DBNull. (Code in VB.NET but I work with C# as well, so feel free to post C# solutions)
[Code]....
dataRow(0) is System.DBNull when the Excel file has a number in Column A. Here's what the Excel looks like
Column A 100S200 WEIRD ABCDEFG 123456 100S12791 119655902 100S12792 105E17530 123456 and 119655902 come through as DBNull

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'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?
I 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:
byte[] data = GetData(excelData); MemoryStream memoryStream = new MemoryStream(data); 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.
The code Export data from GridView to Excel is working fine but in our office network all machines have MS Office2007 so when user click to export data and save the file it is always saving in the old format and when user wants to open that excel file then a popup asks the compatibility of version to open yes or no. So to open the file user everytime click Yes.
I just want to export data from GridView to Excel in MS Office 2007 version, so that when user click to open then it directly open the file without asking any question.
Following is the code which I used in my projects's web pages:
Therefore I cannot try any other code. I just want minor ammendment's in this code to accomplish this task.
Is there a way to import an amount of data from an excel sheet using the sheet rowindex, something like: SELECT * FROM [PLAN1$] WHERE ROWINDEX BETWEEN 1 AND 1000?
Now I need to load the CSV in C # and column 3 to distinguish what the operation is carried out.When the load line in column 3 contain the value 1, so will save the table 'Cats' when the value 2 and is saved in the table "Dogs".(Note: Data are separated ";")
