About formats

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 While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.

KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.

Frequently Asked Questions

Why convert SXW to KWD?

KWD is the native format of KWord in the KDE suite — useful if you work in a KDE desktop environment with Calligra applications.

What software opens KWD?

KWord (now Calligra Words) is the primary editor. Some other KDE-based document tools may also import KWD files natively.

Does formatting carry over?

Text, basic styles, and paragraph structure transfer. Advanced SXW formatting may be simplified in the KWD output file.

Is this free?

Standard SXW to KWD conversion is free. Premium plans provide higher volume limits and priority processing on Convertio.

Can I use this on any OS?

Yes — the web-based converter works in any modern browser on Windows, macOS, Linux, or mobile platforms equally well.

How fast is the conversion?

Most files convert in seconds. Cloud-based processing ensures your device performance remains unaffected during the process.
