I am reading excel sheet using below code but that gives blank data table.
public static DataTable ReadExcel(string fileName)
{
string fileExt = ".xlsx";
string conn = string.Empty;
DataTable dtexcel = new DataTable();
if (fileExt.CompareTo(".xlsx") == 0)
conn = #"provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";Extended Properties='Excel 8.0;HRD=Yes;IMEX=1';"; //for below excel 2007
else
conn = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties='Excel 12.0 Xml;HDR=YES';"; //for above excel 2007
using (OleDbConnection con = new OleDbConnection(conn))
{
try
{
OleDbDataAdapter oleAdpt = new OleDbDataAdapter("select * from [Sheet1$]", con); //here we read data from sheet1
oleAdpt.Fill(dtexcel); //fill excel data into dataTable
}
catch(Exception ex) { }
}
return dtexcel;
}
It displays empty data table as below screenshot.
you forgot few things, like OleDbConnection.Open(); and using OleDbCommand
public DataTable ReadExcel(string fileName)
{
string fileExt = ".xlsx";
string sheetName = "Sheet1$";
string conn = string.Empty;
DataTable dt = new DataTable();
if (fileExt.CompareTo(".xlsx") != 0)
conn = #"provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";Extended Properties='Excel 8.0;HRD=Yes;IMEX=1';"; //for below excel 2007
else
conn = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties='Excel 12.0 Xml;HDR=YES';"; //for above excel 2007
using (OleDbConnection con = new OleDbConnection(conn))
using ( OleDbCommand cmd = new OleDbCommand())
{
con.Open();
try
{
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM [" + sheetName + "]";
dt.TableName = sheetName;
using (OleDbDataAdapter da = new OleDbDataAdapter(cmd))
{
da.Fill(dt);
}
}
catch (Exception ex) { }
}
return dt;
}
try rhis code hope it help you
protected void btn_Click(object sender, EventArgs e)
{
string filename = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(Server.MapPath("File/" + filename));
string CurrentFilePath = Server.MapPath("File/" + filename);
string connectString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + CurrentFilePath + ";Extended Properties=\"Excel 12.0 Xml;HDR=YES;IMEX=1;\"";
OleDbConnection conn = new OleDbConnection(connectString);
conn.Open();
DataTable Sheets = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
foreach (DataRow dr in Sheets.Rows)
{
string sht = dr[2].ToString().Replace("'", "");
OleDbDataAdapter da = new OleDbDataAdapter("Select * From [" + sht + "]", conn);
DataTable dt = new DataTable();
da.Fill(dt);
}
}
For me working following code
string filePath = AppDomain.CurrentDomain.BaseDirectory.Replace("\\bin\\Debug", "").Replace("\\bin\\Release", "");
string fileLocation = filePath + ConfigurationManager.AppSettings["EmployeeDetailsFilePath"];
Stream inputStream = File.Open(fileLocation, FileMode.Open, FileAccess.Read);
IExcelDataReader reader = ExcelReaderFactory.CreateOpenXmlReader(inputStream);
reader.IsFirstRowAsColumnNames = true;
DataSet dataSet = reader.AsDataSet();
inputStream.Dispose();
reader.Dispose();
here must add reference of ExcelDataReader dll in your project.
I am using the below code to import excel data into DB table. The code works fine in my local and when I move this code to server the import fails in between. Also I don't get any error messages and I get a message data saved successfully.
For Ex: The excel has 75,000 data's and only 13,500 records are getting inserted and the size of the excel file is 5 MB.
Any suggestions about the possible problems?

Hi remove the data reader on you code which read the excel file twice and use the dataset to fill out your SQL table:
See below:
DataTable dtexcel = new DataTable();
using (OleDbConnection conn = new OleDbConnection(strCS))
{
conn.Open();
DataTable schemaTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
//Looping a first Sheet of Xl File
DataRow schemaRow = schemaTable.Rows[0];
string sheet = schemaRow["TABLE_NAME"].ToString();
if (!sheet.EndsWith("_"))
{
string query = "SELECT * FROM [" + sheet + "]";
OleDbDataAdapter daexcel = new OleDbDataAdapter(query, conn);
dtexcel.Locale = CultureInfo.CurrentCulture;
daexcel.Fill(dtexcel);
}
}
using (SqlConnection sqlconn = new SqlConnection(strCon))
{
SqlCommand sqlcmd = new SqlCommand(sclearsql, sqlconn);
sqlconn.Open();
sqlcmd.ExecuteNonQuery();
}
using (SqlConnection sqlconn = new SqlConnection(strCon))
{
using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(sqlconn))
{
//Set the database table name
sqlBulkCopy.DestinationTableName = strSqlTable;
sqlconn.Open();
sqlBulkCopy.WriteToServer(dtexcel);
}
}
Have you tried using the dts wizard? it is a nice tool if you have a excel sheet with data.
you use it by opening the command prompt. windowsbutton + r, and the write cmd.
and from in here you write dtswizard
then a wizard opens in a new window where you can select the excel sheet that you want to insert. There is many tutorials on google.
Hope you can use this
I want to import excel file data in to SQL Server but this gives an error as shown below:
external table is not in the expected format xls
I am working on windows 8.1 OS and excel 2013. I am using the following code.
try
{
if (FlUploadcsv.HasFile)
{
string FileName = FlUploadcsv.FileName;
string filePath = "C:\\Users\\admin\\Desktop\\Sheet1.xlsx";
string path = filePath;// string.Concat(Server.MapPath("~/Document/" + FlUploadcsv.FileName));
FlUploadcsv.PostedFile.SaveAs(path);
OleDbConnection OleDbcon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;");
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", OleDbcon);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter(cmd);
ds = new DataSet();
objAdapter1.Fill(ds);
Dt = ds.Tables[0];
}
}
catch (Exception ex)
{
}
First you need to Replace Connection string :
OleDbConnection OleDbcon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;");
With this :
If you are use import for .xls then use below one :
OleDbConnection OleDbcon = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + "; Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"");
If you are use import for .xlsx then use below one :
OleDbConnection OleDbcon = new OleDbConnection(#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + "; Extended Properties='Excel 12.0;HDR=YES;IMEX=1;';");
Try this blow one :
try
{
if (FlUploadcsv.HasFile)
{
OleDbConnection OleDbcon;
OleDbCommand cmd = new OleDbCommand(); ;
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
DataSet ds = new DataSet();
DataTable dtExcelData = new DataTable();
string FileName = FlUploadcsv.FileName;
string filePath = "C:\\Users\\admin\\Desktop\\Sheet1.xlsx";
string path = filePath;// string.Concat(Server.MapPath("~/Document/" + FlUploadcsv.FileName));
FlUploadcsv.PostedFile.SaveAs(path);
if (Path.GetExtension(path) == ".xls")
{
OleDbcon = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + "; Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"");
}
else if (Path.GetExtension(path) == ".xlsx")
{
OleDbcon = new OleDbConnection(#"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + "; Extended Properties='Excel 12.0;HDR=YES;IMEX=1;';");
}
OleDbcon.Open();
cmd.Connection = OleDbcon;
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT * FROM [Sheet1$]";
objAdapter1 = new OleDbDataAdapter(cmd);
objAdapter1.Fill(ds);
dtExcelData = ds.Tables[0];
string consString = "Your Sql Connection string";
/* You want insert into your sql database table using SqlBulkCopy. */
using (SqlConnection con = new SqlConnection(consString))
{
using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con))
{
//Set the database table name
sqlBulkCopy.DestinationTableName = "SqlDatabase Table name where you want insert data";
//[OPTIONAL]: Map the Excel columns with that of the database table
sqlBulkCopy.ColumnMappings.Add(".xls/.xlsx Header column name(Id)", "Your database table column(IndexId)");
.
.
.
con.Open();
sqlBulkCopy.WriteToServer(dtExcelData);
con.Close();
}
}
/* You want insert into your sql database table using SqlBulkCopy. */
}
}
catch (Exception ex)
{ }
Here is a similar way to do it:
string filename = System.IO.Path.GetFileName(FileUpload1.FileName);
if (FileUpload1.HasFile == true) {
string fp = System.IO.Path.GetDirectoryName(FileUpload1.FileName);
string full = "C:\\Users\\user\\Documents\\" + filename;
TextBox1.Text = full;
//FileUpload1.SaveAs(Server.MapPath("Files/" + filename))
try {
string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=full;Extended Properties=Excel 8.0;HDR=YES;";
string cmdStr = "Select * from [Sheet1$]";
using (OleDbConnection oledbconn = new OleDbConnection(connStr)) {
using (OleDbCommand oledbcmd = new OleDbCommand(cmdStr, oledbconn)) {
oledbconn.Open();
OleDbDataAdapter oledbda = new OleDbDataAdapter(oledbcmd);
DataSet ds = new DataSet();
oledbda.Fill(ds);
//save to an SQL Database
oledbconn.Close();
}
}
} catch (Exception ex) {
TextBox2.Text = ex.ToString();
}
}
I want to import data from an Excel 2003 file, but my C# program gives error

{
//Check the Content Type of the file

{
try
{
//Save file path
string path = string.Concat(Server.MapPath("~/TempFiles/"), fileuploadExcel.FileName);
//Save File as Temp then you can delete it if you want
fileuploadExcel.SaveAs(path);
string excelConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"";

Hi here i am using this to import from Excel File.Try this.Works 100%...
Here you should have a folder inside your application named as "Files" where after uploading your excel file,it will be stored and your program will read from the excel file available inside "Files" Folder.
protected void btnImport_Click(object sender, EventArgs e)
{
ArrayList alist = new ArrayList();
string connString = "";
string strFileType = Path.GetExtension(fileuploadExcel.FileName).ToLower();
string fileBasePath = Server.MapPath("~/Files/");
string fileName = Path.GetFileName(this.fileuploadExcel.FileName);
string fullFilePath = fileBasePath + fileName;
//Connection String to Excel Workbook
if (strFileType.Trim() == ".xls")
{
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fullFilePath +
";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"";
}
else if (strFileType.Trim() == ".xlsx")
{
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fullFilePath +
";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=1\"";
}
if (fileuploadExcel.HasFile)
{
string query = "SELECT [UserName],[Education],[Location] FROM [Sheet1$]";
using(OleDbConnection conn = new OleDbConnection(connString))
{
if (conn.State == ConnectionState.Closed)
conn.Open();
OleDbCommand cmd = new OleDbCommand(query, conn);
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
Session["griddata"] = ds.Tables[0];
grvExcelData.DataSource = Session["griddata"];
grvExcelData.DataBind();
}
}
}
Try this: Connection String
string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;";
You can use SSIS tool( Sql server integration services)
create connection to excel sheet then add source and destination
your source will be excel sheet and your destination will be Database table
ok?
if you need more info please tell me...
I am trying to find the best way of selecting an excel spreadsheet (xls and xlsx) using a fileupload control and then parsing it with filestream object and then populating a dataset.
This is my code so far which does the job but how it differs is I am saving the excel spreadsheet to a folder in my solution then querying the data using Microsoft ACE OLEDB connection.
protected void btnUpload_Click(object sender, EventArgs e)
{
string connectingString = "";
if (ctrlFileUpload.HasFile)
{
string fileName =
Path.GetFileName(ctrlFileUpload.PostedFile.FileName);
string fileExtension =
Path.GetExtension(ctrlFileUpload.PostedFile.FileName);
//Path.GetExtension(ctrlFileUpload.PostedFile.ContentType);
string fileLocation =
Server.MapPath("~/App_Data/" + fileName);
ctrlFileUpload.SaveAs(fileLocation);
// Check whether file extension is xls or xslx
if (fileExtension == ".xls")
{
connectingString =
"Provider=Microsoft.ACE.OLEDB.4.0;Data Source=" +
fileLocation + ";Extended Properties=\"Excel 8.0;HDR=YES;IMEX=2\"";
}
else if (fileExtension == ".xlsx")
{
connectingString =
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
fileLocation + ";Extended Properties=\"Excel 12.0;HDR=YES;IMEX=2\"";
}
// Create OleDb Connection and OleD Command
using (OleDbConnection con = new OleDbConnection(connectingString))
{
try
{
OleDbCommand cmd = new OleDbCommand();
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd);
//DataTable dtExcelRecords = new DataTable();
DataSet ds = new DataSet();
con.Open();
DataTable dtExcelSheetName = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
string getExcelSheetName = dtExcelSheetName.Rows[0]["Table_Name"].ToString();
cmd.CommandText = "Select * FROM [" + getExcelSheetName + "]";
dAdapter.SelectCommand = cmd;
//dAdapter.Fill(dtExcelRecords);
dAdapter.Fill(ds);
//GridView1.DataSource = dtExcelRecords;
//GridView1.DataBind();
}
catch (Exception ex)
{
}
}
}
}
So to summarise I want to read the data in a spreadsheet and then bind it to a dataset but without saving the file to a physical path.
Is there a cleaner way of writing this code that I am missing. Thanks!!
I think it not possible to get data without save file to your server
If you can't save uploded file how can you give Data Source to your oleDbConnection string ??
you can delete file after finish this execution if you don't want to keep the file.
you can also refer this way https://stackoverflow.com/a/12420416/284240
