The .xlsx is an open source filename extension format developed by Microsoft in collaboration with ISO/IEC and ECMA. It is part of the Open Document family of file formats. The .xlsx is associated with spreadsheet authoring applications particularly with Microsoft's Office Excel 2007 and above. The format has existed since 2005 and is also supported by several other proprietary and open source spreadsheet authoring software other than Microsoft's Office Excel. The xlsx format is the default filename extension for all spreadsheet documents produced using Microsoft Office Excel 2007 SP2 and above.
The Open Document spreadsheet filename extension format is an alternative open source spreadsheet file format and is part of the larger OpenDocument family of open source file formats. The format is associated with documents where tabular or spreadsheet information is represented. Several proprietary and open source applications are compatible with the format, allowing for interoperability between software systems that support the OpenDocument format. Proprietary applications such as in Microsoft Office Excel 2007 and above can open .ods files however certain proprietary features in Microsoft Office Excel may not be compatible with the format. Other open source spreadsheet applications (such as OpenOffice) support the .ods filename extension in its entirety.

The xlsx filename extension is a compressed archive with an xml directory structure. It is specified in the open standard ISO/IEC 29500-1:2012. .xlsx files do not support macros by design, for that, the .xlsm format should be used. A free compatibility update allows older versions of Microsoft Office Excel such as Office 2003 to open .xlsx documents.
The ods file format extends the XML based file format for spreadsheets. It was standardized as an open source format for spreadsheet type documents in ISO/IEC 26300:2006 in 2005 by the OASIS consortium. It supports spreadsheet features such as OLE objects, hyperlinks, cell formating as well as advanced features such as cell formulas.
