Databases :: Reading Data From An Excel Workbook (.xls)
Mar 1, 2011I 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)");
}

looks like below
Sno Description

// based on the preceding SQL SELECT statement.
