OpenOffice.org XML is an open XML-based file format developed as an open community effort by Sun Microsystems in 2000–2002. The open-source software application used the format as their native and default file format for saving files. The XML format is no longer widely used, but it is still supported in recent versions. That is why we are one of the rare websites providing this format so outdated customers can save their files without any hassle and help them assist not to lose the saved files and documents in this format.
