Convert Markdown to SXW

Why Convert Markdown to SXW?

Converting Markdown to SXW is necessary when you need to produce documents compatible with legacy OpenOffice.org 1.x installations, StarOffice 6/7 environments, or archival systems that require the original OpenOffice.org Writer format. While SXW has been superseded by ODT, it remains relevant for organizations maintaining older document management systems.

Markdown, created by John Gruber in 2004, is the dominant documentation format on modern platforms like GitHub, Stack Overflow, and Reddit. Converting Markdown content to SXW bridges the gap between contemporary writing practices and legacy office environments, ensuring that modern documentation can be accessed by older systems that only understand the SXW format.

SXW was introduced with OpenOffice.org 1.0 in 2000 by Sun Microsystems. It uses a ZIP archive containing XML files for content, styles, and metadata. This XML-based approach was revolutionary at the time and later evolved into the OASIS Open Document Format (ODF), which became the ISO standard. SXW can be considered the direct ancestor of the modern ODT format.

While most users should prefer ODT for new documents, SXW conversion remains important for archival compliance, legacy system compatibility, and situations where government or institutional requirements mandate the original OpenOffice.org format. LibreOffice and Apache OpenOffice continue to support SXW files for backward compatibility.

Key Benefits of Converting Markdown to SXW:

• Legacy Compatibility: Works with OpenOffice.org 1.x and StarOffice 6/7
• Open Format: XML-based, documented, and non-proprietary
• Rich Formatting: Supports styles, tables, images, and layout
• Archival Compliance: Meets requirements for legacy format archives
• LibreOffice Support: Fully readable and editable in modern LibreOffice
• Compressed Storage: ZIP archive for smaller file sizes
• Migration Path: Easily convertible to modern ODT format later

Frequently Asked Questions (FAQ)

Q: What is SXW format?

A: SXW is the native document format of OpenOffice.org Writer 1.x, introduced by Sun Microsystems in 2000. It is a ZIP archive containing XML files that store the document content, styles, and metadata. SXW was the default Writer format until OpenOffice.org 2.0 adopted the OASIS Open Document Format (ODT) in 2005.

Q: What is the difference between SXW and ODT?

A: Both are XML-based ZIP archives for word processor documents, but they use different XML schemas. SXW uses the OpenOffice.org 1.x XML format, while ODT uses the OASIS Open Document Format (ODF), which became an ISO standard. ODT is the modern successor with broader support, better standardization, and more features. SXW is considered a legacy format.

Q: Can I open SXW files in modern software?

A: Yes! LibreOffice and Apache OpenOffice fully support SXW files for both reading and writing. Microsoft Word can import SXW files with some limitations. Google Docs can also open SXW files. For best results, use LibreOffice Writer, which provides complete backward compatibility with the SXW format.

Q: Why would I need SXW instead of ODT?

A: Use SXW only when specifically required for compatibility with OpenOffice.org 1.x installations, StarOffice 6/7 environments, or legacy document archival systems that mandate the original OpenOffice.org format. For all other purposes, ODT is the recommended format as it is the modern standard with wider support.

Q: Will Markdown formatting be preserved in SXW?

A: Yes, all standard Markdown formatting converts well to SXW. Headings become Writer heading styles, bold and italic are preserved as character formatting, lists become formatted lists, and tables are converted to Writer tables. Code blocks are rendered in monospace font. The SXW format supports all the formatting that Markdown can express.

Q: Is SXW an open format?

A: Yes, SXW is an open, documented format. The XML schema was publicly available, and the format was the basis for the OASIS Open Document Format standardization effort. Anyone can read and write SXW files without licensing restrictions. The open nature of SXW was one of OpenOffice.org's key advantages over proprietary formats.

Q: Can I convert SXW to other formats later?

A: Absolutely! SXW files can be opened in LibreOffice and saved as ODT, DOCX, PDF, HTML, or any other format that LibreOffice supports. This makes SXW a reasonable intermediate format - you can always convert to modern formats when needed. Our converter also supports converting SXW to many other document formats.

Q: How large are SXW files compared to Markdown?

A: SXW files are typically larger than Markdown source files because they include XML markup, style definitions, and metadata. However, since SXW is ZIP-compressed, the size increase is moderate. A 10 KB Markdown file might produce a 20-40 KB SXW file, depending on the amount of formatting and content. SXW files are generally smaller than equivalent DOC files.
