TOML vs SXW Format Comparison

Aspect TOML (Source Format) SXW (Target Format)
Format Overview
TOML
Tom's Obvious Minimal Language

A minimal configuration file format created by Tom Preston-Werner in 2013. Designed for obvious semantics and formally specified. Supports typed values including strings, integers, floats, booleans, dates, arrays, and tables. Standard format for Cargo.toml, pyproject.toml, Hugo, and Netlify.

Modern Config Typed Values
SXW
StarOffice/OpenOffice.org Writer

A document format used by StarOffice and early versions of OpenOffice.org Writer. Based on XML stored within a ZIP archive. Predecessor to the ODF (Open Document Format) standard. While considered legacy, SXW files are still encountered in archived documents and organizations that used StarOffice or early OpenOffice.org installations.

Legacy Format OpenOffice Origin
Technical Specifications
Structure: Hierarchical tables and key-value pairs
Encoding: UTF-8 required
Data Types: String, Integer, Float, Boolean, DateTime, Array, Table
Nesting: Tables and inline tables
Extensions: .toml
Structure: ZIP archive containing XML files
Encoding: UTF-8 (XML content)
Data Types: Formatted text, tables, images, styles
Nesting: XML element hierarchy
Extensions: .sxw
Syntax Examples

TOML uses structured key-value pairs:

[company]
name = "Acme Corporation"
founded = 1985
employees = 250

[company.address]
street = "123 Business Ave"
city = "Springfield"
state = "IL"
zip = "62701"

SXW contains XML within ZIP archive:

<office:body>
  <text:h text:style-name="Heading_1">
    Company Information
  </text:h>
  <text:p>
    Name: Acme Corporation
  </text:p>
  <text:p>
    Founded: 1985
  </text:p>
</office:body>

Why Convert TOML to SXW?

Converting TOML configuration files to SXW format is necessary when working with legacy OpenOffice.org or StarOffice environments that require documents in the original SXW format. While SXW has been largely superseded by the ODT (Open Document Text) standard, some organizations and archival systems still operate with SXW as their primary document format due to long-established workflows or regulatory requirements.

The SXW format, introduced with OpenOffice.org 1.0 in 2000, uses an XML-based structure stored within a ZIP archive. This architecture was the precursor to the OASIS Open Document Format (ODF) that became an ISO standard. Converting TOML to SXW creates formatted documents with section headings derived from TOML tables, organized key-value displays, and professional styling that OpenOffice.org and LibreOffice can open and edit natively.

This conversion serves organizations that maintain document archives in SXW format. Configuration documentation, system reports, and project metadata stored in TOML can be converted to SXW for integration into existing document management systems. The formatted output includes proper headings, tables for structured data, and paragraph styles that conform to the SXW document model.

For migration scenarios, converting TOML to SXW can serve as an intermediate step. Organizations moving from legacy StarOffice systems to modern platforms can first generate SXW documents from their configuration data, then use LibreOffice or other tools to batch-convert these documents to ODT, DOCX, or PDF. This staged approach ensures compatibility at each step of the migration process.

Key Benefits of Converting TOML to SXW:

  • Legacy Compatibility: Works with OpenOffice.org 1.x and StarOffice
  • Archive Integration: Fits into existing SXW document repositories
  • Formatted Output: Headings, tables, and styled content
  • LibreOffice Ready: Opens seamlessly in modern LibreOffice
  • XML Foundation: Clean, structured document internals
  • Migration Step: Bridge between config data and document systems
  • Compressed Format: ZIP container keeps file sizes small

Practical Examples

Example 1: Organization Configuration Report

Input TOML file (org-config.toml):

[organization]
name = "Regional Health Authority"
code = "RHA-2024"
region = "Northwest District"

[organization.contact]
phone = "+1-555-0123"
email = "[email protected]"
address = "450 Government Plaza, Suite 200"

[systems]
ehr_version = "3.8.1"
database = "Oracle 19c"
backup_schedule = "daily"

Output SXW file (org-config.sxw):

SXW document containing:

Frequently Asked Questions (FAQ)

Q: What is SXW format and why is it still used?

A: SXW is the native document format of OpenOffice.org 1.x and StarOffice. While replaced by ODT (Open Document Text) in 2005, SXW files persist in organizational archives, legacy document management systems, and environments that still run older StarOffice or OpenOffice installations. Some government and institutional archives maintain SXW documents from the early 2000s.

Q: Can LibreOffice open SXW files?

A: Yes. LibreOffice Writer fully supports opening, editing, and saving SXW files. It can also convert SXW to modern formats like ODT or DOCX. Apache OpenOffice, Calligra Suite, and some other office applications also support SXW.

Q: How are TOML tables represented in the SXW document?

A: TOML table names become section headings in the SXW document with appropriate heading styles. Key-value pairs are rendered as formatted text with bold keys and indented values. Nested tables create subsection hierarchies with incrementing heading levels.

Q: Should I use SXW or ODT for new documents?

A: For new documents, ODT (Open Document Text) is strongly recommended. ODT is the ISO-standardized successor to SXW with better features, broader support, and active development. Use SXW only when specifically required for compatibility with legacy systems or archival requirements.

Q: Can I convert the SXW file to other formats later?

A: Yes. LibreOffice can convert SXW to ODT, DOCX, PDF, HTML, RTF, and many other formats. This makes SXW useful as an intermediate format when bridging between configuration data and various document requirements.

Q: How does SXW differ from ODT internally?

A: Both SXW and ODT use XML within a ZIP archive. However, SXW uses the pre-OASIS XML namespace and schema, while ODT follows the formal OASIS Open Document Format specification (ISO/IEC 26300). The structural concepts are similar, but the exact XML elements and attributes differ between the two formats.

Q: Will TOML data types be visible in the SXW output?

A: TOML values are rendered as formatted text in the SXW document. Numeric values appear as numbers, booleans as true/false or Yes/No, and dates in human-readable format. The document format does not enforce data types, but the visual representation preserves the semantic meaning of each value.

Q: Can Microsoft Word open SXW files?

A: Microsoft Word has limited SXW support. Some versions can import SXW files, but the results may not be perfect. For best compatibility with Microsoft Word, consider converting to DOCX or RTF instead. LibreOffice provides the most reliable SXW support and can serve as an intermediary for conversion to Word-compatible formats.
