BBCode vs SXW Format Comparison

Aspect BBCode (Source Format) SXW (Target Format)
Format Overview
BBCode
Bulletin Board Code

Lightweight markup language used in online forums and message boards. Uses square bracket tags like [b], [i], [url] to format text. Designed for safe user-generated content where HTML is restricted. Widely adopted across phpBB, vBulletin, SMF, and other forum platforms.

Forum Markup User-Friendly
SXW
StarOffice/OpenOffice.org Writer Document

Legacy document format used by StarOffice and early versions of OpenOffice.org Writer (before version 2.0). SXW files are ZIP archives containing XML-based content, styles, and metadata. Predecessor to the ODF (Open Document Format) standard. Still encountered in archival settings and legacy document management systems.

Why Convert BBCode to SXW?

Converting BBCode to SXW format is necessary when forum content needs to be integrated into legacy document management systems that rely on the StarOffice/OpenOffice.org 1.x Writer format. While SXW has been superseded by ODT (Open Document Text), many organizations, particularly in government and education sectors, still maintain archives and workflows built around this earlier format. Converting BBCode to SXW ensures compatibility with these legacy environments.

SXW files are ZIP archives containing XML documents that describe content, styles, and metadata. This XML-based structure is a precursor to the ODF standard, offering a structured approach to document storage. When BBCode content is converted to SXW, the formatting tags are translated into XML elements within the content.xml file: bold text becomes styled spans, lists are converted to proper list structures, and links become hyperlink elements with proper anchoring.

The conversion is particularly relevant for organizations migrating historical forum data into document management systems. Government agencies that adopted StarOffice in the early 2000s may still have workflows that accept SXW files. Educational institutions with legacy OpenOffice.org installations can open and edit SXW documents directly. By converting forum content to SXW, you bridge the gap between web-based community content and institutional document standards.

Modern applications like LibreOffice can still open and convert SXW files, making them accessible even in current environments. However, if you do not have a specific need for SXW format, consider converting to the modern ODT (Open Document Text) format instead, which offers broader compatibility, more features, and active development. SXW conversion is best suited for targeted legacy system integration rather than general-purpose document creation.

Key Benefits of Converting BBCode to SXW:

  • Legacy Compatibility: Works with StarOffice and OpenOffice.org 1.x systems
  • XML Structure: Clean, inspectable document structure inside ZIP archive
  • Format Preservation: BBCode formatting translated to SXW styles
  • Compressed Storage: ZIP compression keeps file sizes manageable
  • LibreOffice Support: Modern LibreOffice can open and edit SXW files
  • Archive Standard: Suitable for legacy document archives
  • Migration Path: SXW files can be batch-converted to ODT when ready

Frequently Asked Questions (FAQ)

Q: What is the SXW format?

A: SXW is the native document format used by StarOffice Writer and OpenOffice.org Writer versions 1.0 through 1.1.5 (2000-2005). It is a ZIP archive containing XML files for content, styles, metadata, and settings. SXW was replaced by the ODT format when OpenOffice.org 2.0 adopted the OASIS Open Document Format (ODF) standard in 2005.

Q: Can modern software open SXW files?

A: Yes, LibreOffice and Apache OpenOffice can open SXW files and convert them to modern formats. When you open an SXW file in LibreOffice, it is automatically imported and can be saved as ODT, DOCX, or PDF. However, Microsoft Word does not natively support SXW files, so conversion to another format is needed for Word compatibility.

Q: What is the difference between SXW and ODT?

A: Both SXW and ODT are ZIP archives containing XML documents, but they use different XML schemas. SXW uses the older OpenOffice.org 1.x XML format, while ODT uses the standardized OASIS Open Document Format (ODF). ODT is an international standard (ISO/IEC 26300), has broader software support, more features, and is actively maintained. SXW is considered legacy.

Q: Why would I need SXW instead of ODT?

A: You would need SXW specifically if you are working with legacy systems that only accept the OpenOffice.org 1.x format, maintaining compatibility with old StarOffice installations, or adding documents to an archive that uses SXW as its standard. For all other purposes, ODT is the recommended choice as it is the modern successor with wider support and more features.

Q: How is BBCode formatting preserved in SXW?

A: BBCode formatting tags are converted to SXW style definitions stored in the styles.xml file within the ZIP archive. Bold text creates a text style with font-weight:bold, italic creates font-style:italic, and colors are mapped to style attributes. Lists become proper XML list elements, and links are stored as hyperlink elements in the content.xml file.

Q: Can I batch convert SXW files to ODT?

A: Yes, LibreOffice supports batch conversion via command line: libreoffice --headless --convert-to odt *.sxw. This makes it easy to migrate an entire collection of SXW documents to the modern ODT format. The conversion preserves formatting, styles, and content while updating the underlying XML schema to the ODF standard.

Q: What is inside an SXW file?

A: An SXW file is a ZIP archive containing: content.xml (the main document text and structure), styles.xml (formatting and style definitions), meta.xml (document metadata like author and date), settings.xml (application settings), and a META-INF/manifest.xml file listing the archive contents. You can examine these files by renaming .sxw to .zip and extracting.

Q: Is SXW an open format?

A: Yes, SXW is an open format. Its XML schema was publicly documented by Sun Microsystems as part of the OpenOffice.org project. This openness was a key advantage over Microsoft's proprietary DOC format at the time. The SXW format's openness directly influenced the development of the ODF standard, which formalized and improved upon SXW's XML-based approach to document storage.
