Web Forms :: Reading Data From An Excel Document Posted Via FileUpload Control?
Jun 9, 2010
I am working on a comparison tool that will take an excel file and a .csv file and find differences. The user is going to be selecting the two files from their local machine via the .NET FileUpload control. The issue I am running into is that I don't want to write the files to the server first so using something like below won't work for me, as "Book1.xls" or even " + FilePath + " in place of it won't work. I need to be able to read the posted files into memory, then create maybe datatables of them, then do my comparison code.
[Code]....
I have some code that reads the PostedFile into a stream but I don't know how I can use that stream with the above code. Then I have some that can read the .csv file, but if it is an excel file, I get a bunch of Excel garbage along with the data...
[Code]....
How can I read into clean data from a FileUpload control of an Excel document?

I have made an application to read data from an excel file and save to database "Access". It's working perfect except one thing that..There are 4 columns in excel file as :
Shop no
owner address
alternate member address
permanent member address
For all fields i have kept same datatype in database as "text". As in above image In Column A "shop no" in some rows there are same shop no with A,B,C classes. Now when I am uploading this excel file it saving all data, but in Column A cells which having only numbers would be saving to database eg: 185, 187, 188. And the cells which has both number and class eg: 185 A, 185 B would be reading as null values.

1) I need to make reading CSV file from the fileupload and then retrieve the data.
2) I need to load CSV and the 3 columns rise two functions.
Load CSV data and then stored in a database, but I need to save storage space vary according to 3 column.
CSV Example:
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2
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 ";")

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 am trying to read data from excel file in asp.net. I have added the connection string to webConfig file:
<add name="xls" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=HPM_DB.xls;Extended Properties=Excel 8.0"/>
But it shows me an errormessage when I run this query:
string query = "Select * from [IO_Definition$]";
IO_Definition is the name of the spreadsheet in my excel file. I also added the excel file to the App_Data folder of the website.
The error is:
The Microsoft Jet database engine could not find the object 'IO_Definition$'. Make sure the object exists and that you spell its name and the path name correctly.
The thing is, when I write the absolute path of the excel file in the connectionString it does work. Is there anyway I can make it work without writing the absolute path?

I have a client that provides a .xls file on their site that we have no control over that we download the file and then read it to update inventory. The first column is the SKU and in cell A2 it has the value 1028. This outputs fine but when I get to A8 the value is '1051-LV' and in my output it is blank. I am thinking in my dataset it reads A2 value and that becomes the type for the remainder of the rows. But what if that is wrong? How do I fix so it doesn't set the datetype to say int when it could be a string type?
Below is my code and works but the output of certain rows sku values are blank and are not like that in the excel file.
Code:
Protected Sub btnGetExcelFile_Click(sender As Object, e As System.EventArgs) Handles btnGetExcelFile.Click
litOutput.Text = ""
Dim ws As New WebPost
ws.URL = "http://www.domain.com/dropship/feed.xls"
'downloads excel file based on url
Dim bExcel() As Byte = ws.RequestBinaryData("", True)

[Code]....
But some times the file that is read, reports that there is more rows than there actually are. i.e. I only have 300 lines of data but the read reads in 500. My question is, and I am sure I have seen this somewhere but I cannot find it now, is how do I get the reader to stop reading at the first blank line?

We have some table with messages. Each message could have attachments.
We need to have text of attachmnet inside html table of messages on web page. For the first stage we need to have at least support of doc, excel attachments (in future possibly will desire pdf). So in table we show from, subject and body as html cells of message tr. And cell for body should contain firstly rendered content of attached documents (with all images and styles), and then real message body. They don't want any links for download or something similar :(
I know only about possibility to use MS Word Save As logic (but don't have a lot of details). So in this case I should have MS word, excel installed on server. And based on type of attachment use one of the compopnents.
