What is an SXC file?
An .SXC file is a spreadsheet document created by early versions of OpenOffice.org or StarOffice. Specifically, it is a StarOffice Calc Spreadsheet originally developed by Sun Microsystems. Underneath the surface, an .SXC file is a standard ZIP compressed archive that holds XML files. These XML files store the rows, columns, formulas, and formatting of your spreadsheet data.
How to open SXC files?
Because .SXC is a legacy format, many older systems used the original StarOffice software to edit them. Today, the most reliable desktop software to open an .SXC file is LibreOffice Calc or Apache OpenOffice Calc. Modern versions of Microsoft Excel can also import these files in most cases. If you want to look at the internal XML structure of the spreadsheet, you can rename the .SXC file extension to .ZIP and extract it with archiving tools like 7-Zip or WinRAR.
Inspecting and Converting SXC Files
Since the .SXC file format is older, it can sometimes be difficult to know the exact software version that created it. viewer.online/sxc analyzes .SXC files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need to edit the file permanently on modern systems, we recommend file conversion to sensible target formats like .ODS, .XLSX, or .CSV on convert.guru.
Summary
Handling legacy spreadsheet files does not have to be difficult. viewer.online/sxc directly opens and previews .SXC files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
