Here Mudassar Ahmed Khan has explained with an example, how to read (import) Excel file without using OLEDB or installing Microsoft Office Excel or Interop Library in C# and VB.Net.

The Excel file will be read using ClosedXml and OpenXml DLLs which does not require OLEDB and does not require Microsoft Office Excel or Interop Library software to be installed.

In this article I will explain with an example, how to read (import) Excel file without using OLEDB or installing Microsoft Office Excel or Interop Library in C# and VB.Net.

The Excel file will be read using ClosedXml and OpenXml DLLs which does not require OLEDB and does not require Microsoft Office Excel or Interop Library software to be installed.

 
 
Download DocumentFormat.OpenXml and ClosedXml Libraries

You can download the libraries using the following download locations.

Download OpenXml SDK 2.0 (http://www.microsoft.com/en-in/download/details.aspx?id=5124)

Download ClosedXml Library (https://github.com/ClosedXML/ClosedXML)

 Note: The DLL files of both OpenXml and ClosedXml are present in the attached sample.

 
Form Controls

I have added a DataGridView and a Button to the Windows Form. I have also added an OpenFileDialog to the Form which allow us to select the excel file.

Namespaces

You will need to import the following namespaces.

C#

using System.IO;
using System.Data;
using ClosedXML.Excel;
 
VB.Net

Imports System.IO
Imports System.Data
Imports ClosedXML.Excel
 

 
Selecting the Excel File

When the Select File button is clicked, it shows the Open File Dialog, using which we need to select the Excel file we want to import to DataGridView control.

C#

private void btnSelect_Click(object sender, EventArgs e)


{
    openFileDialog1.ShowDialog();
}
 
VB.Net

Private Sub btnSelect_Click(sender As Object, e As EventArgs) Handles btnSelect.Click


    OpenFileDialog1.ShowDialog()

End Sub

 
Importing the Excel File’s Sheet to DataGridView control

When the Open Button is clicked, the following event handler is executed. First the path of the selected Excel file is read and then the Excel file is read using the ClosedXml WorkBook class object.

Then the instance of the first Sheet is determined and all the rows present in the Sheet are fetched.

Finally a loop is executed over the fetched rows and a DataTable is populated which is then used to populate the DataGridView.

C#

private void openFileDialog1_FileOk(object sender, System.ComponentModel.CancelEventArgs e)


{
    string filePath = openFileDialog1.FileName;
 
    //Open the Excel file using ClosedXML.
    using (XLWorkbook workBook = new XLWorkbook(filePath))
    {
        //Read the first Sheet from Excel file.
        IXLWorksheet workSheet = workBook.Worksheet(1);
 
        //Create a new DataTable.
        DataTable dt = new DataTable();

                int i = 0;
                foreach (IXLCell cell in row.Cells())
                {
                    dt.Rows[dt.Rows.Count - 1][i] = cell.Value.ToString();
                    i++;
                }
            }
 
            dataGridView1.DataSource = dt;
        }
    }
}
 
VB.Net

Private Sub openFileDialog1_FileOk(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk


    Dim filePath As String = OpenFileDialog1.FileName
    'Open the Excel file using ClosedXML.

Just want to thank you very much for this article. I have spent hours searching for a solution to a very similar page I am building and I was giving up hope on getting it to work.

Thanks to this page and this site.
