Hi Arun,

first load excel sheet into dataset and find text in dataset.

use below sample code to load excel to dataset:

C#

public void LoadallAttributions(string filePath)
        {
            IExcelDataReader excelReader = null;
            DataSet result = new DataSet();
            FileStream stream = null;
            try
            {
                stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
                if (String.Compare(Path.GetExtension(filePath), ".xls", true) == 0)
                    excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
                else if (String.Compare(Path.GetExtension(filePath), ".xlsx", true) == 0)
                    excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);

                if (excelReader != null)
                {
                    excelReader.IsFirstRowAsColumnNames = true;
                    result = excelReader.AsDataSet();
                    dataset = result;

                }
            }
            catch (Exception ex)
            {
               // clsErrorLog.WriteErrorLog(ex);
                MessageBox.Show(Path.GetFileName(filePath).ToString() +" file opened out side the application, please close and try again.");

            }
            finally
            {
                //if (excelReader != null && !excelReader.IsClosed)
                //{
                    excelReader.Close();
                    excelReader.Dispose();
               // }
                if (stream != null)
                {
                    stream.Close();
                    stream.Dispose();

                }
            }
           // return result;

           
        }
