About SXC files
The .SXC file extension represents a legacy spreadsheet format created by Sun Microsystems for OpenOffice.org 1.0 and StarOffice. Under the hood, it is a ZIP-compressed archive containing XML data that dictates rows, columns, formulas, and cell formatting. You can open these files natively using LibreOffice Calc or Apache OpenOffice. However, maintaining files in the .SXC format is a severe liability today. It is an obsolete standard that was officially replaced by the ODS (OpenDocument Spreadsheet) format over fifteen years ago. Modern commercial tools, notably Microsoft Excel, do not natively support .SXC, resulting in immediate compatibility roadblocks and workflow friction. To guarantee your data remains accessible, you must convert it. For modern open-source compatibility, convert to ODS. For seamless integration into corporate environments, convert to XLSX. If you only need the raw data stripped of all fragile formatting, convert to CSV. For archiving read-only financial reports, convert to .PDF/A. Drag and drop your file here to analyze and convert it securely right in your browser without installing obsolete software.

The SXC Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SXC converter.
