What “reviewed” means on this page
  • Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
  • Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
  • Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
  • Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
  • Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

What is a .ODS file?

.ODS is a file format for spreadsheets, part of the OpenDocument Format (ODF) standard. It is widely used for storing data in a structured format with support for formulas, charts, and more.

Background

The .ODS file format is part of the OpenDocument Format (ODF) standard, which was developed to provide an open and vendor-neutral document format. It is primarily used by open-source office suites like LibreOffice and Apache OpenOffice, but it is also supported by other software, including some versions of Microsoft Excel. ODS files are popular in environments that prioritize open standards and interoperability. They are often used in educational and governmental institutions where open-source software is preferred. The format supports a range of spreadsheet features, including complex formulas, charts, and data analysis tools. Despite its open nature, users may encounter compatibility issues when using certain proprietary software, but these are generally resolved by using compatible applications.

Common MIME types: application/vnd.oasis.opendocument.spreadsheet
