Native access to Excel files. The user doesn't need to have Excel, or any other software installed. XLSReadWriteII uses it's own memory manager that is optimized for storing cell values. This means that you can work with larger files. If your files still not will fit in memory, there is a Direct Read and Direct Write modes that let you process files on disc. Stability. One of the major goals with XLSReadWriteII was to create a product that won't corrupt the Excel files and won't alter any data in the file. The engine that handles XLSX files is automatically built directly from the file format specifications with our special developed tool. This will ensure maximum compatibility.

How can XLSReadWriteII help you?

Native access to Excel files. The user doesn't need to have Excel, or any other software installed.
XLSReadWriteII works as an invisible Excel workbook. All cell values are always accessible.
Stability. One of the major goals with XLSReadWriteII was to create a product that won't corrupt the Excel files and won't alter any data in the file.
XLSReadWriteII is easy to use. With the formatting interface, you can format cells through a cell object.
Fast and efficient support when you have any questions.
No runtime fees for the component.
Full source code included.
We released the first version of XLSReadWrite in 1998. At that time it was the only component that could read and write Excel 97+ files. We are commited to have the leading Excel solution for Delphi in the future as well.

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.

Performance

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.
Support for all Excel formatting options.
