What is an ODS file?

The OpenDocument Spreadsheet (ODS) format is an XML-based file standard for spreadsheets, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). Standardized as ISO/IEC 26300, ODS utilizes a ZIP-compressed container holding separate XML files for content (content.xml), styles, and metadata. It serves as the native file format for the LibreOffice and Apache OpenOffice suites, offering a vendor-neutral alternative to proprietary formats by strictly adhering to the OpenDocument Format (ODF) specifications.

How to open an ODS file

ODS files are natively supported by open-source suites such as LibreOffice Calc and Apache OpenOffice on Linux, Windows, and macOS. Microsoft Excel (versions 2007 SP2 and later) includes built-in support for opening and saving ODS files, though some formatting variations may occur due to ODF version differences. Google Sheets also provides cloud-based support for importing and editing this format.

What is an XLSM file?

The XLSM format is a macro-enabled spreadsheet file created by Microsoft Excel 2007 and later versions, utilizing the Office Open XML (OOXML) standard (ISO/IEC 29500). Unlike the standard XLSX format, XLSM files store embedded macros written in Visual Basic for Applications (VBA), allowing for automation and complex scripting within the workbook. The file structure relies on ZIP compression to contain XML documents for data, styles, and macro binary parts (vbaProject.bin), presenting a security risk that often requires user authorization to execute active content.

How to open an XLSM file

XLSM files open natively in Microsoft Excel (2007+) on Windows and macOS, which provides full VBA execution support. For non-Microsoft environments, LibreOffice Calc, OpenOffice Calc, and WPS Office can open these files and view data, though VBA macro execution compatibility varies significantly. Google Sheets can import XLSM data but strips the VBA macros, converting the file to its native format without automation features.
