Can free software really replace Microsoft Office?
For everyday documents the free suites are a straight replacement, and all of them read and write .docx, .xlsx and .pptx. Differences appear mainly in very complex formatting and in advanced Excel features such as macros and pivot models.
Being honest about it: free alternatives are not always a feature-for-feature match, and anyone telling you otherwise is selling something. What they are is free — so the cost of finding out whether they cover your particular workflow is an hour of your time rather than a subscription.
