Office Open XML (OOXML) is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations, and word processing documents. It was standardized by Ecma International as ECMA-376 and later by ISO and IEC as ISO/IEC 29500.
OOXML is used in various Microsoft Office applications, such as Word, Excel, and PowerPoint. The file formats include:
.docx for word processing documents
.xlsx for spreadsheets
.pptx for presentations
The format is designed to be open and interoperable, allowing different software applications to read and write OOXML files. This makes it easier to share and collaborate on documents across different platforms and devices.
