What is an SXC file?
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.
How to open an SXC file
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.

What is a CSV file?
A Comma-Separated Values (CSV) file is a delimited text file format codified under RFC 4180 that uses commas to separate values and newlines to separate records. The format stores tabular data (numbers and text) in plain ASCII or Unicode text, where each line constitutes a data record with identical field sequences. It lacks a formalized schema for styling or formulas, relying solely on character separation for data structure, making it a standard for platform-independent data exchange between disparate database management systems (DBMS).
How to open a CSV file
Due to its plain text architecture, CSV files possess universal native support across all major operating systems. They can be viewed and edited using simple text editors like Microsoft Notepad or Vim, but are optimally managed with spreadsheet software such as Microsoft Excel, LibreOffice Calc, or Google Sheets, which parse the delimiters to render the data into columns.
