Convert SDM to ODF

Understanding SDM and ODF file formats

SDM files are spreadsheet documents created by StarOffice Calc, a component of the now-discontinued StarOffice suite. These files were commonly used in the early 2000s before the adoption of the OpenDocument standard. ODF (OpenDocument Format) is a modern, open standard for office documents, including spreadsheets, and is widely supported by applications like LibreOffice Calc and Apache OpenOffice Calc.

Why convert SDM to ODF?

Converting SDM files to ODF ensures better compatibility with current office software, improved data security, and easier document sharing. ODF is an open, ISO-standardized format, making it a preferred choice for long-term document storage and collaboration.

How to convert SDM to ODF

Since SDM is an outdated format, direct conversion tools are rare. The best approach is to use LibreOffice or Apache OpenOffice, which still offer some support for legacy StarOffice files.

1. Download and install LibreOffice or Apache OpenOffice from their official websites.
2. Open the application and go to File → Open, then select your SDM file.
3. Once the file is loaded, go to File → Save As or File → Export.
4. Choose ODF Spreadsheet (.ods) as the target format and save the file.

If you encounter issues opening SDM files, you may need to use an older version of OpenOffice or seek out a StarOffice installation for initial conversion to a more accessible format.

Recommended software for SDM to ODF conversion

• LibreOffice Calc – Free, open-source, and supports a wide range of legacy formats.
• Apache OpenOffice Calc – Another free office suite with legacy file support.

Both tools are available for Windows, macOS, and Linux, making them accessible for most users.

Summary

Converting SDM to ODF is best achieved using LibreOffice or Apache OpenOffice. These applications provide the necessary compatibility to open and save your old StarOffice spreadsheets in the modern, widely supported ODF format.
