What is an SDC file?
SDC is the legacy spreadsheet format used by StarOffice Calc and early OpenOffice.org releases, the predecessor suites to LibreOffice Calc. It stores cell data, formulas, and formatting using StarOffice's original binary document model, which was superseded by the OpenDocument Spreadsheet (ODS) standard. SDC files typically surface today only when working with archived StarOffice-era spreadsheets.
How to open an SDC file
LibreOffice Calc opens SDC files natively through its built-in legacy StarOffice format support, converting the spreadsheet into its modern editing environment automatically. Apache OpenOffice Calc also supports this older format.

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.
