.NET xlReader for Microsoft Excel is a set of classes, specifically designed to read Microsoft Excel files from .NET applications. The latest version of the component is implemented as a .NET Managed Provider with read-only capabilities which allow it to read data from native Microsoft Excel files without the need to use Microsoft Excel or any additional providers. This also results in a familiar look-and-feel and allows for future extension of the component. .NET xlReader uses 100% .NET managed code and is designed to use minimal PC memory to achieve maximum performance.

There are some limitations with this provider...

- No support for password-protected Excel files.

- .NET xlReader for Microsoft Excel supports only Excel files saved in a BIFF8 binary format supported by Microsoft Excel 97 or newer version of Microsoft Excel and Excel files saved in XLSX format supported by Microsoft Excel 2007 or newer version of Microsoft Excel.

- Limited support for the SQL statements. Current version of the reader supports only delimited list of the spreadsheet names in following format: "shreadsheetname1;spreadsheet2;.... spreadsheetN;" and treats each spreadsheet as a table. List of the spreadsheet names should contain at least one spreadsheet name. See more details inside of examples on how to query data from the spreadsheets.

- Component does not support updates of the data from the DataTable/DataSet to the underlying Microsoft Excel file. ExcelDataAdapter allows populating DataTable/DataSet with the data from the spreadsheet(s), but current version does not support updates.
