Three apps, one suite
VibeOffice bundles a word processor, a spreadsheet and a presentation editor — each opens and saves the real formats.
Quire — word processor
Edit .docx, .docm, .dotx, .dotm, .rtf, .htm, .txt and Markdown (.md, or a .zip with pictures), and export to PDF. Content controls, comments, watermarks and numbering come through in VibeOffice.
Ledger — spreadsheet
Edit .xlsx, .xlsm, .xltx, .xltm, .csv and XML Spreadsheet 2003, and export to PDF. Pivot tables, slicers, timelines and threaded comments survive a round trip in VibeOffice.
Lectern — presentations
Edit .pptx, .pptm, .ppsx, .ppsm, .potx and .potm, and export to PDF, PNG or .htm. Media, sections, custom shows and unused slide layouts are preserved in VibeOffice.
Lossless editing
What it cannot edit yet, it keeps. VBA macros, embedded objects, SmartArt, ink, 3-D models and custom XML are written back byte for byte by VibeOffice.
Private by design
Everything runs on your machine. There is no server behind it, no upload and no sign-in — your documents never leave your computer.
Installable
In Chrome or Edge, install it from the Start Center. It then opens .docx, .xlsx and .pptx files straight from your file manager.
