No subscription, no internet required — here is how to open .docx, .xlsx and .pptx files for free on Windows.
The easy way: install one free suite
If you regularly receive Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) files, the simplest solution is one free suite that opens all of them. Xrero Office does exactly that — four apps, one free download, fully offline.
Step by step
- Download Xrero Office free from xrero.com/office and run the installer on Windows 10 or 11.
- Double-click any Office file — Word, Excel and PowerPoint documents open in the matching app.
- Edit and save — files keep their original format, so others open them normally.
Works offline, keeps your files private
Unlike online viewers and converters, nothing is uploaded anywhere. Documents open on your PC even with no internet connection — ideal for work laptops, schools and travel.
Arabic documents too
Arabic and mixed Arabic/English files open with correct right-to-left layout and shaping — Xrero Office was built Arabic-first.
FAQ
Can I edit the files or only view them?
Full editing — Writer, Calc and Slides are complete editors, not viewers.
Do I need a Microsoft account?
No account of any kind is needed.
What other formats open?
.doc, .xls, .ppt, .odt, .ods, .odp, .rtf, .csv and .pdf, among others.
