 XLSReadWriteII 5 works with Delphi/C++Builder/RAD Studio 5 to XE8. Firemonkey (Win and OSX) is supported
Here are some of the advantages that you will have with XLSReadWriteII 5:

 Read and write any cell values...
  • Numeric, string, boolean and error cells. But what about date and time cells? There are no such cells in Excel. Excel store date and time values in the same way as Delphi, i.e. as floating point numbers. What make's it a date or time value, is the formatting.
  • Full support for formulas. You can use the same functions as in Excel. Formulas with referrences to external workbooks are supported as well. You can even read the result from an external referrense.
  • Cells are accessed in the same way as the TStringGrid that comes with Delphi, or by giving the cell as a string, like: 'D7'.
  • Read cell values as a string formatted according to the rules of the cell.


  • XLSReadWriteII is designed with optimal performance in mind. As Excel 2007+ files permits up to 16,000 x 1,000,000 cells, performance is important.
  • Read and write speed of Excel 2007+ files at least twice as fast as Excel. As these files are compressed XML files both decompressor anb XML parser must be fast.
  • XLSReadWriteII uses it's own memory manager. Memory usage shall not be more than half of what
    Excel uses, and most times it's much less than that.
  • Due to the fact that pre Excel 2007 files are binary file, these files are read and written much faster.

 Format the cells as you want...
  • Formatting is easy. By adressing the cell, you can access the formatting properties for it. Example: XLSReadWriteII.Sheet[n].Cell[Col,Row].FontSize := 12;
  • XLSReadWriteII has objects for formatting a worksheet in the same way as the Excel Format Cells dialog. You can format cells or areas of cells in the same way as Excel.
