Advantages of the XML Formats
- Files are more compact. In most cases, if you compare the size of an Office file saved in the binary format, with the same file saved in the equivalent Open XML format, the XML-formatted file will be smaller. This is largely because of the compression applied
to the Open XML files. However, files that contain a large number of graphics may not be smaller, because the graphics cannot be further compressed by the zip algorithm.
- Easier corrupted file recovery.
- Easier to locate and parse content.
- Files can be opened and edited with any XML editor.
- Files containing macros are easier to identify.
- it is useful when you try to automate Office files on server side, because on server side office interop give some errors on certain condition and situation but open XML works without any issue.
it is same for all office applications.
