- Is LibreOffice enough to replace Microsoft Office?
- For most home and student work, yes. Complex Excel macros and rare formatting edge cases may need testing. Export to PDF when sharing with Office-only workplaces.
- Does OnlyOffice look more like Microsoft Office?
- OnlyOffice desktop has a ribbon-style UI closer to modern Office. LibreOffice is more classic but fully capable.
