SXC to Excel Converter — Frequently Asked Questions ▼

SXC (StarOffice XML Calc) is the native spreadsheet format of StarOffice 6-7 and early OpenOffice.org 1.0-1.1, from approximately 2001-2005. The format was superseded by ODS (OpenDocument Spreadsheet) when OpenOffice.org adopted the OpenDocument standard. Neither LibreOffice Calc nor Microsoft Excel opens .sxc files in their current versions — the format is exclusively legacy archive material requiring conversion.
Standard mathematical and statistical formulas (SUM, AVERAGE, IF, VLOOKUP, etc.) use equivalent syntax in both StarOffice Calc and Excel and convert correctly. StarOffice-specific functions with no Excel equivalent are converted to their closest Excel counterpart where possible, or stored as static values. Review formulas in complex SXC files after conversion to verify calculation results.
Yes. All sheets in the SXC workbook are converted to corresponding sheets in the XLSX output. Sheet names, sheet order, and inter-sheet formula references are preserved.
StarOffice was Sun Microsystems' commercial office suite. Sun open-sourced the code in 2000, creating OpenOffice.org. When Oracle acquired Sun in 2010, community developers forked the project to create LibreOffice. Oracle donated OpenOffice.org to Apache in 2011. LibreOffice is now the actively developed successor; Apache OpenOffice development is largely dormant. SXC is the format from the original StarOffice/early OpenOffice.org era.
SXC files are uncommon in general use but do appear in specific contexts: enterprise and government organizations that deployed StarOffice or early OpenOffice.org in the early 2000s, particularly in Germany, the Netherlands, Brazil, and other regions that adopted open-source software in government. Organizations archiving data from that era may encounter SXC files on backup tapes or legacy servers.
StarOffice charts use StarChart format, which does not have a direct mapping to Office Open XML chart objects. Charts embedded in SXC files typically do not convert to Excel charts. The underlying data table the chart was based on converts correctly as cell data — you can recreate the chart in Excel from the converted data.
The online converter handles multiple SXC file uploads. For migrating entire directories of legacy StarOffice Calc files to XLSX — from backup tapes, legacy server archives, or optical media — Total Excel Converter (Windows, $29.90) processes entire folder hierarchies with command-line automation support.
 

 

Convert SXC to Excel Online — Migrate StarOffice Calc Files to XLSX

SXC is the spreadsheet format from StarOffice and early OpenOffice.org — software discontinued over a decade ago. Modern applications like Microsoft Excel, LibreOffice Calc, and Google Sheets do not open SXC without conversion. Converting SXC to Excel XLSX brings the data and formulas into the current standard format, making the content accessible and editable without legacy software.

What Is SXC?

SXC (StarOffice XML Calc) is the native spreadsheet format of StarOffice (versions 6–7) and early OpenOffice.org (1.0–1.1), predating the OpenDocument standard. StarOffice was Sun Microsystems' commercial office suite, widely deployed in enterprise and government environments in the early 2000s as a low-cost Microsoft Office alternative. When Sun donated the code and the project became OpenOffice.org, the format evolved into ODS (OpenDocument Spreadsheet). SXC files store cell data, formulas, styles, and sheet structure in XML. No currently distributed spreadsheet application saves SXC; the format is exclusively legacy archive material.

What Is Excel (XLSX)?

XLSX is the Office Open XML spreadsheet format introduced in Microsoft Excel 2007, now the dominant spreadsheet standard. XLSX stores workbooks in a ZIP archive containing XML files for sheets, formulas, styles, and shared strings. It is supported natively by Microsoft Excel, LibreOffice Calc, Google Sheets, Apple Numbers, and every modern spreadsheet application. Converting SXC to XLSX makes the data accessible in any current environment without legacy StarOffice software.

Who Has SXC Files?

What Converts from SXC to XLSX

Cell values, formulas, multiple sheets, and basic cell formatting transfer to XLSX. StarOffice-specific formula functions that have no XLSX equivalent are converted to their closest XLSX counterpart or stored as values. Charts embedded in the SXC may not transfer depending on their type and complexity.
