SXC to GIF Converter

The SXC (StarOffice Calc) format is a legacy XML-based spreadsheet file developed by Sun Microsystems for the StarOffice suite (versions 5.2 through 7.0). It acts as the technical predecessor to the modern OpenDocument (ODS) standard. The format utilizes ZIP compression to encapsulate XML data describing cell values, formulas, and formatting. While largely obsolete following the standardization of ODF in 2005, SXC remains significant in the history of open-source office software development.

Modern native OS support for SXC is non-existent without third-party tools. The most reliable software for opening SXC files is LibreOffice Calc or Apache OpenOffice, both of which maintain backward compatibility with legacy StarOffice formats. Microsoft Excel does not support SXC natively and requires file conversion prior to access.

The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.

GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
