What it is

An open-source office suite from The Document Foundation. It opens, edits and saves Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) files, and is free for personal and business use alike. It is the most widely used alternative where buying Microsoft Office is not an option.

When to pick this

If you mainly read documents and make light edits. For complex Excel macros or precise layout work, you still need MS Office.

Details

MS Office compatibility

Opens and saves docx, xlsx and pptx. Complex formatting and macros may shift, so check important documents before sending them on.

PDF export

Any document can be saved as PDF without a separate program.

Business use

No licence cost even when installed across a company. If your internal templates are built for MS Office, test compatibility first.
