    Note

    Please try the latest source from the repo before reporting issues as there have been recent changes.
    Also, if you are reporting an issue it is really useful if you can supply an example excel file as this makes debugging much easier and without it we may not be able to resolve any problems.

    How to use

    C# code :

    FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
    
    //1. Reading from a binary Excel file ('97-2003 format; *.xls)
    IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
    //...
    //2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
    IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
    //...
    //3. DataSet - The result of each spreadsheet will be created in the result.Tables
    DataSet result = excelReader.AsDataSet();
    //...
    //4. DataSet - Create column names from first row
    excelReader.IsFirstRowAsColumnNames = true;
    DataSet result = excelReader.AsDataSet();
    
    //5. Data Reader methods
    while (excelReader.Read())
    {
    	//excelReader.GetInt32(0);
    }
    
    //6. Free resources (IExcelDataReader is IDisposable)
    excelReader.Close();
    

    VB.NET Code:

    Dim stream As FileStream = File.Open(filePath, FileMode.Open, FileAccess.Read)
    
    '1. Reading from a binary Excel file ('97-2003 format; *.xls)
    Dim excelReader As IExcelDataReader = ExcelReaderFactory.CreateBinaryReader(stream)
    '...
    '2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
    Dim excelReader As IExcelDataReader = ExcelReaderFactory.CreateOpenXmlReader(stream)
    '...
    '3. DataSet - The result of each spreadsheet will be created in the result.Tables
    Dim result As DataSet = excelReader.AsDataSet()
    '...
    '4. DataSet - Create column names from first row
    excelReader.IsFirstRowAsColumnNames = True
    Dim result As DataSet = excelReader.AsDataSet()
    
    '5. Data Reader methods
    While excelReader.Read()
        'excelReader.GetInt32(0);
    End While
    
    '6. Free resources (IExcelDataReader is IDisposable)
    excelReader.Close()
