Xlsx format


What is exactly the official name of xlsx format created.
Is there any difference between office2007 and office2010?


XLSX is an Open Office XML based file format and both Excel 2007 and 2010 support this file format. Please check the topic for further reference:

Thank you.

it’s not crystal clear which output is linked to which format.

In aspose.cells.SaveForamt there are several constants. Which of them corresponds to MS Excel 2007, and MS Excel 2010?


Please use SaveFormat.XLSX constant for MS-Excel 2007 and 2010 files.

Let me tell you, Ms-Excel 2007 and Ms-Excel 2010 both saves the file in XLSX format.
