In an effort to create an open document standard, Microsoft in collaboration with ISO/IEC and Ecma, developed the Office Open XML standard in 2006. One of the filename extensions supported in this specification is the .docx extension, a text document filename extension. The .docx was introduced in Microsoft Office Word 2007 and has been supported ever since in later iterations. It has become the default filename extension for all text documents produced using Microsoft Office Word. Given the open source nature of the XML specification, more alternative document processing applications support read and write capabilities on documents saved with the .docx filename extension. This is in comparison to the .doc filename extension which is a proprietary asset owned by Microsoft.
StarOffice, otherwise known as Oracle Open Office, was a proprietary office suite initially released in 1985 and developed by Sun Microsystems before being acquired by Oracle. Prior to adopting the Open Document XML file format, the suite had its own proprietary components and filename extensions for word processing, spreadsheets, presentations, databases, and drawing. The .sxw filename extension was one such filename extension associated with the native file format of documents authored by the Star Office Writer (a word processor) application version 6 and above. Prior to this version, the filename extension .sdw was used.
FreeFileConvert uses tuned encoding for DOCX to SXW conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload DOCX files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized SXW results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent SXW audio with dependable progress tracking.
The .docx filename extension is specified in the open standard ISO/IEC 29500-1:2012. A free compatibility update allows older versions of Microsoft Office Word such as Office 2003 to open .docx documents.
The sxw format is part of the Star office xml format which was later discontinued in favor of the open document standard. The format uses an XML structure contained in a ZIP archive. Compression is not used for document meta data allowing for easier searching and or extraction.
Upload your document file in the DOCX format from your device, Dropbox, or Google Drive.
Select SXW as the output format and click Convert. Adjust optional settings if needed.
Download the converted document file. Each file stays available for up to 5 downloads.
