About formats

TXT (Plain Text) is the most fundamental digital document format, storing unformatted text as a sequence of character codes with no embedded styling, layout instructions, or metadata beyond the characters themselves. The foundation of plain text computing traces to the ASCII standard published in 1963 by the American Standards Association (now ANSI), which defined 128 character codes including uppercase and lowercase Latin letters, digits, punctuation, and control characters. Modern plain text files typically use UTF-8 encoding, a variable-width Unicode scheme that encompasses virtually every writing system worldwide while maintaining backward compatibility with ASCII. Line endings vary by platform convention — LF on Unix/macOS, CR+LF on Windows — though most contemporary tools handle both transparently. One advantage is absolute universality — TXT files can be created, read, and edited on every computing device ever manufactured, from 1960s mainframes to modern smartphones, without any specialized software. The minimal overhead is another core strength: plain text carries zero formatting baggage, making TXT files ideal for configuration files, log output, data interchange, source code, scripts, and any context where content must be processed programmatically. Plain text serves as the substrate for structured formats like CSV, JSON, XML, YAML, and Markdown, and remains the input/output medium for virtually all command-line tools and programming environments. Despite decades of richer alternatives, TXT endures as the one truly universal document format.

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.
