Free online SDC to CSV converter

An older StarOffice Calc spreadsheet may need to go into a database or data-processing tool that accepts CSV but not SDC. Exporting it as CSV makes the sheet’s tabular data available as delimited text.

What the SDC format is

SDC is a legacy spreadsheet format used by StarOffice Calc. Older office-document archives may contain SDC workbooks with cell data, formulas, formatting, and multiple sheets. LibreOffice Calc can open many SDC files.

What the CSV format is

CSV is plain text that stores rows of values, with fields separated by a delimiter such as a comma or semicolon. Spreadsheet applications, databases, and data-processing tools commonly accept it. Unlike a spreadsheet workbook, CSV does not preserve formatting, charts, formulas as formulas, or multiple sheets in one file.

How to convert SDC to CSV

Online on 101convert.com

1. Upload the SDC file on the converter page. You can convert several files in one batch; the per-file size limit is shown on the page.
2. Before converting, set the column separator, character encoding, and sheets as needed.
3. Convert the file and download the CSV output. The conversion runs on the service’s server with LibreOffice.

Offline with desktop software

LibreOffice Calc is free and runs on Windows, macOS, and Linux. Open the file with File → Open, then choose File → Save As and select Text CSV (.csv) as the file type. In the export dialog, choose the character encoding and field separator expected by the receiving application, then confirm the export. CSV contains one sheet, so export each required sheet separately.

Quality and compatibility

Calc exports formula cells as their calculated values, not as editable formulas; charts and spreadsheet formatting are not retained. Check the exported values, especially dates, numbers with leading zeros, and text containing the chosen delimiter. The receiving application must use a compatible separator and character encoding to read the fields correctly.
