Frequently Asked Questions

What is the difference between ODS and XLSX?

ODS is an open standard format, while XLSX is Microsoft's proprietary format. Both are XML-based and support similar spreadsheet features, but ODS prioritizes interoperability and open standards.

Technical Details

An ODS file is essentially a ZIP archive containing multiple XML files and potentially other resources like images. The primary XML file, 'content.xml', defines the spreadsheet's structure, data, and formatting.

Did You Know?

ODS is part of the OpenDocument Format (ODF) family of standards, which aims to provide a royalty-free, XML-based file format for office applications.
The structure of an ODS file can be viewed by simply renaming the extension to .zip and extracting its contents, revealing the underlying XML files.

Security Information

ODS files are generally considered safe as they are primarily data containers. However, like any file, they can potentially contain malicious scripts if opened with a compromised application or if the underlying XML is manipulated.
