I am trying to select the "Report Details" worksheet from my excel file. However, I am having trouble selecting it,
The Microsoft Jet database engine could not find the object 'Report Details'. Make sure the object exists and that you spell its name and the path name correctly.
if (fileExtension == ".xls")
{
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
}
else if (fileExtension == ".xlsx")
{
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
OleDbConnection con = new OleDbConnection(connString);
OleDbCommand cmd = new OleDbCommand();
cmd.CommandType = System.Data.CommandType.Text;
cmd.Connection = con;
OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd);
DataTable dtExcelRecords = new DataTable();
con.Open();
DataTable dtExcelSheetName = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
cmd.CommandText = "SELECT * FROM [Report Details]"; //ERROR HERE
dAdapter.SelectCommand = cmd;
dAdapter.Fill(dtExcelRecords);
con.Close();
GridView1.DataSource = dtExcelRecords;
GridView1.DataBind();
Viewing my "Tables" in the dataset viewer, the connection string is able to access the file. The Report Details column is displayed as 'Report Details$'. I have tried entering it that way, but I am still getting an error.
Your question title says EXCEL/C# Cant Find Worksheet
Your post says I am trying to select the "Report Details" WORKSHEET from my excel file.
The error you are getting is
The Microsoft Jet database engine could not find the object 'Report Details'. Make sure the object exists and that you spell its name and the path name correctly.
Solution
You are missing a $ sign
Try this (TRIED AND TESTED)
cmd.CommandText = "SELECT * FROM [Report Details$]";
I was able to get the tabel name throuh dtExcelSheetName
cmd.CommandText = "SELECT * FROM [" + con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[1][2].ToString() + "]";
It is working now.

I am building an app to read measurement data (saved as .xls files on our network) from comparators throughout our facility via a Webform. When I query this group of files I only retrieve the headers. My code (pretty standard) will read any other Excel file I can find. I tried to remove a file from the network and save it locally, as well as rename and save it from office 2016. Note - these are .xls files and I can't change that.
** - I just discovered that there are named ranges with the same name as the file. The results I am getting are just the values in the named range and not the data from the workbook.
Here is an example of how they are named (autogenerated) "R87_1RCR0009654S_COIN"
If I rename or remove the named range this works fine.
Is there a way I can change my select statement to read these?
Here is a code sample, not sure there if there is a change I can make here to read these files.
private string Excel03ConString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'";
private string Excel07ConString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'";
string conStr, sheetName;
conStr = string.Format(Excel03ConString, info.FullName, "YES");
string fullPathToExcel = info.FullName;
//Get the name of the First Sheet.
using (OleDbConnection con = new OleDbConnection(conStr))
{
using (OleDbCommand cmd = new OleDbCommand())
{
cmd.Connection = con;
con.Open();
DataTable dtExcelSchema = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
sheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
con.Close();
}
}
using (OleDbConnection con = new OleDbConnection(conStr))
{
using (OleDbCommand cmd = new OleDbCommand())
{
using (OleDbDataAdapter oda = new OleDbDataAdapter())
{
DataTable dt = new DataTable();
cmd.CommandText = "SELECT * From [" + sheetName + "]";
cmd.Connection = con;
con.Open();
oda.SelectCommand = cmd;
oda.Fill(dt);
con.Close();
}
}
}
I Want to skip a few rows in an excel file, 15 rows(A1 to A14) to be able to import in sql server... But What I'm finding in internet doesn't work with me, I was thinking if you guys could take a look in my code
protected void Upload_Click(object sender, EventArgs e)
{
string excelPath = Server.MapPath("~/Nova pasta/") + Path.GetFileName(FileUpload1.PostedFile.FileName);
string filepath = Server.MapPath("~/Nova pasta/") + Path.GetFileName(FileUpload1.FileName);
string filename = Path.GetFileName(filepath);
FileUpload1.SaveAs(excelPath);
string ext = Path.GetExtension(filename);
String strConnection = #"Data Source=PEDRO-PC\SQLEXPRESS;Initial Catalog=costumizado;Persist Security Info=True;User ID=sa;Password=1234";
string excelConnectionString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Extended Properties=\"Excel 12.0 Xml;HRD=YES;IMEX=1;\"";
OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
OleDbCommand cmd = new OleDbCommand("Select * from [rptListaMovs_4$]", excelConnection);
excelConnection.Open();
cmd.ExecuteNonQuery();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("Select * from [rptListaMovs_4$] ", strConnection);
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
using (SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection))
{
sqlBulk.DestinationTableName = "Dados";
sqlBulk.ColumnMappings.Add("Data Mov", "Data Mov.");
sqlBulk.ColumnMappings.Add("Data Valor", "Data Valor");
sqlBulk.ColumnMappings.Add("Descrição do Movimento", "Descrição do Movimento");
sqlBulk.ColumnMappings.Add("Valor em EUR", "Valor em EUR");
sqlBulk.WriteToServer(dReader);
}
excelConnection.Close();
}
I already tried put the "IEnumerable" but it didn't work, I probably did it wrong.
If you know you always want to skip exactly the first 14 rows and start your query importing at A15, then you can write your SQL query like this:
Select * from [rptListaMovs_4$A15:G]
Replace G with the correct column Letter
P.S. Credit to this answer for this inspiration.
#MacroMarc and ADyson Helped me
Here's the solution:
OleDbCommand cmd = new OleDbCommand("Select * from [rptListaMovs_4$A15:D75]", excelConnection);
Insted of This:
OleDbCommand cmd = new OleDbCommand("Select * from [rptListaMovs_4$]", excelConnection);
I have a requirement to import the excel file in ASP.NET MVC. The importing is working as needed, there are 78 columns in the excel file. all the columns are imported except the last column.
How could I retrive last column from the excel file?
string conString = string.Empty;
if (getFileExtension.ToLower() == ".xls")
{
conString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + getFileName + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\""; ;
}
else if (getFileExtension.ToLower() == ".xlsx")
{
conString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + getFileName + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
OleDbConnection con = new OleDbConnection(conString);
if (con.State == ConnectionState.Closed) con.Open();
DataTable ExcelSheets = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
string SpreadSheetName = ExcelSheets.Rows[0]["TABLE_NAME"].ToString();
string query = "SELECT * FROM [" + SpreadSheetName + "]";
OleDbCommand cmd = new OleDbCommand(query, con);
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
da.Dispose();
con.Close();
con.Dispose();
According to Import from excel to datatable skipping last column values, this may be an Excel or OleDb bug.
As a workaround, you might consider modifying the Excel sheet so as to add an additional column header at the end, with no data in the column. Then, the column that is skipped during import will be the one you don't need.
I have run into a snag when reading info from a workbook in excel that contains a "#" in the name of the sheet. I am able to select the WHOLE worksheet but not a range in the worksheet.
Code:
using (OleDbConnection conn = new OleDbConnection())
{
DataTable dt = new DataTable();
string Import_FileName = "C:/TestExcel/TestWorkbook.xlsm";
conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Import_FileName + ";" + "Extended Properties='Excel 12.0 Xml;HDR=YES;'";
using (OleDbCommand comm = new OleDbCommand())
{
comm.CommandText = "Select * from [Sheet #1$A1:A22]";
comm.Connection = conn;
using (OleDbDataAdapter da = new OleDbDataAdapter())
{
da.SelectCommand = comm;
da.Fill(dt);
}
}
}
And the following queries work just fine.
comm.CommandText = "Select * from [Sheet #1$]";
comm.CommandText = "Select * from [Sheet2$A1:A22]";
I get the following exception saying it cannot find the table in question.
The Microsoft Office Access database engine could not find the object 'Sheet .1$A1:A22'.
I have Excel files that are in 2000 & 2003 format. I need to import them via C# code into an access DB. I have written a method to read the file into a data table. No matter which connection string i use (I have checked the other posts on this topic) I continue to get "Table is not in the correct format" error. Can someone please explain to me what I am doing wrong.
public static DataSet ParseExcel(string excelFile)
{
string sheetName = Path.GetFileNameWithoutExtension(excelFile);
string excelQuery = #"SELECT * FROM [" + sheetName + "]";
string excelConnctionString = #"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + "" + excelFile + "" +
#";Extended Properties=" + "" + #"Excel 8.0;HDR=Yes;" + "";
if(File.Exists(excelFile))
{
var myConnection = new OleDbConnection(excelConnctionString);
myConnection.Open();
var myCommand = new OleDbDataAdapter(excelQuery, excelConnctionString);
myCommand.TableMappings.Add("Table", "TestTable");
var dtSet = new DataSet();
myCommand.Fill(dtSet);
myConnection.Close();
return dtSet;
}
return null;
}
Go through this code example carefully and try to understand the work flow. You will get it real easy to write any kind programs for accessing excel data according to your requirements.
1.Here I just have a Upload Field in order to select the Excel File in .aspx file
<asp:FileUpload ID="Upload_File" runat="server" />
<asp:Button ID="Upload_Button" runat="server" Text="Upload" onclick="btnUpload_Click"/>
<asp:GridView ID="Gridview_Name" runat="server">
</asp:GridView>
Now lets see what happens in code behind file (.aspx.cs file)
protected void Upload_Button_Click(object sender, EventArgs e)
{
string connectionString = "";
if (Upload_File.HasFile) // checking whether file is selected to be uploaded
{
//getting name of the file
string fileName = Path.GetFileName(Upload_File.PostedFile.FileName);
//getting extension of the file (for checking purpose - which type .xls or .xlsx)
string fileExtension = Path.GetExtension(Upload_File.PostedFile.FileName);
string fileLocation = Server.MapPath("" + fileName); //exact location of the excel files
Upload_File.SaveAs(fileLocation);
//Check whether file extension is xls or xslx
if (fileExtension == ".xls")
{
connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
}
else if (fileExtension == ".xlsx")
{
connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
//Create OleDB Connection and OleDb Command
OleDbConnection con = new OleDbConnection(connectionString);
OleDbCommand cmd = new OleDbCommand();
//cmd.CommandType = System.Data.CommandType.Text;
cmd.Connection = con;
OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd);
DataTable dtExcelRecords = new DataTable();
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);
con.Close();
Gridview_Name.DataSource = dtExcelRecords;
GridView_Name.DataBind();
}
else
{
Response.Write("Please Select a File to extract data ");
}
}
Step by Step Explanation :
We get the file name, extension, location .
And check it is the type (.xls or .xlsx - particularly for excels of 2003 or other formats).
Set connection strings according to the previous step.
Open oledb connection
Create the necessary data adapter and data table
open the connection
store the current table( where the data from excel is stored) in a datatable instance
Store the name of the sheet in astring by getting it from the current table
Fill the data adapter object(dAdapter) with the our data table (dtExcelRecords)
close the connection
Set datasource for the grid as out data table.
Bind it with our grid.
...And We are done!
Hope it helps.
Try this
OLEDB;Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";
