SXC File Format

Overview

The SXC file format, standing for Sun XML Calc, is part of the OpenOffice.org office suite. Designed to meet the needs of spreadsheet enthusiasts, SXC files are XML-based documents that support a wide range of features such as formulas, functions, macros, and charts. One of its standout features is DataPilot, which automatically summarizes raw imported data in an individualized manner. This makes SXC an excellent choice for users who need robust data analysis capabilities without the complexity of more advanced tools.

SXC files are widely used by developers and technical professionals who work with OpenOffice Calc or LibreOffice Calc. These formats offer a free alternative to proprietary software, making them popular among those looking to reduce licensing costs while maintaining powerful functionality.

Key Features

  • XML-Based Structure: SXC files leverage XML for storing spreadsheet data, allowing for easy parsing and manipulation.
  • DataPilot Functionality: Automatically summarizes raw imported data in an individualized manner.
  • Compatibility with OpenOffice and LibreOffice: Seamlessly integrates with these office suites, providing a robust alternative to Microsoft Excel.
  • Supports Formulas and Functions: Enables complex calculations and data analysis within spreadsheets.
  • Macros and Charts: Allows for automation through macros and visual representation of data via charts.

Technical Specifications

Format Structure

SXC files are XML-based documents stored as ZIP archives. This structure allows them to contain multiple parts, such as header information, spreadsheet content, and metadata, all encapsulated within a single file.

Core Components

  • Header: Contains metadata about the document.
  • Body: The main section where actual spreadsheet data is stored in XML format.
  • Metadata Files: Additional files that provide extra information like styles and macros.

Standards & Compatibility

SXC files adhere to specific content types:

  • application/vnd.sun.xml.calc
  • application/vnd.sun.xml.calc.template

These formats ensure compatibility with Apache OpenOffice Calc, LibreOffice Calc, and other software supporting the SXC format. The format also supports exporting data to Microsoft Excel and other spreadsheet formats.

History & Evolution

SXC was introduced as part of StarOffice (later rebranded as OpenOffice.org) in the late 1990s. It aimed to provide a free and open-source alternative to proprietary office suites, focusing on XML-based document storage for better interoperability and ease of use. Major milestones include improvements in DataPilot functionality, enhanced compatibility with other formats like Microsoft Excel, and continuous updates to support modern computing environments.
