About formats

DOTX is the Open XML template format for Microsoft Word, introduced with Office 2007. A DOTX file is a ZIP archive containing XML parts that define document styles, page layout defaults, theme colors, theme fonts, numbering formats, boilerplate content, headers, footers, and other elements that establish a reusable document foundation. When applied, a DOTX template creates a new DOCX document inheriting the template's complete formatting system. The XML-based structure provides advantages over the legacy DOT format: templates can be inspected and modified using standard XML tools, individual components (styles, themes) are cleanly separated into dedicated files, and ZIP compression yields smaller file sizes. One advantage is modular design management — DOTX templates encapsulate a complete formatting identity as a distributable package, and the XML architecture makes it straightforward to update specific elements like color schemes or font definitions without rebuilding the entire template. Broad compatibility is another strength: DOTX templates work in Word on Windows and macOS, LibreOffice Writer, and online platforms including Google Docs (with conversion). The format integrates with Word's template management system and organizational template libraries via SharePoint, enabling centralized document governance across large teams. DOTX has become the standard for distributing document formatting frameworks in corporate, academic, and publishing environments.

SXW is the word processing document format used by StarOffice 6.0 and OpenOffice.org 1.0, developed by Sun Microsystems and released in 2002. The format was one of the first mainstream office document formats to adopt an XML-based architecture, packaging document content, styles, metadata, and embedded media in a ZIP archive — a structural approach that directly influenced the later OpenDocument Format (ODF). The content.xml file describes the document body using XML elements for paragraphs, headings, lists, tables, footnotes, and inline formatting, while styles.xml defines the styling rules and meta.xml carries document properties. SXW represented a significant milestone in open-source office software, demonstrating that a non-proprietary XML format could handle the full range of word processing features including change tracking, indexes, cross-references, and complex page layouts. One advantage was transparency and openness — the XML structure made document content inspectable, transformable, and processable using standard tools, a sharp contrast to the opaque binary formats dominant at the time. The format's role as a technological precursor to the ODF standard is another historical significance: the OASIS OpenDocument Technical Committee used the OpenOffice.org XML format (including SXW) as the starting point for developing ODF 1.0. While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.

Frequently Asked Questions

Why convert DOTX to SXW?

SXW is the legacy StarOffice and early OpenOffice Writer format — useful when working with older systems or archives that require it.

What opens SXW files?

LibreOffice Writer, Apache OpenOffice, and legacy StarOffice installations open SXW files. Some modern apps can import them as well.

Does formatting survive conversion?

Core text formatting, paragraphs, tables, and basic styles transfer well. Some modern template features may simplify in the older format.

Can I batch convert DOTX to SXW?

Yes — upload several DOTX templates at once and convert them all to SXW in one Convertio session. No repeated uploads needed.

Is DOTX to SXW free?

Basic conversions are free on Convertio. Premium accounts offer larger file sizes and priority processing for demanding workflows.

Is SXW the same as ODT?

No — SXW predates ODT. SXW was the native format for StarOffice/OpenOffice.org 1.x, while ODT is the newer open standard successor.
