Why VibeOffice
- Familiar. The menus, toolbars and task panes of the classic Office 2003 look, so there is nothing new to learn.
- Lossless editing. Open what colleagues send you, and save files built to open in Microsoft Office and LibreOffice, without losing what you didn't touch (below).
- Private. Everything runs on your machine. There is no server behind it, no upload and no sign-in.
- Installable. In Chrome or Edge, install it from the Start Center. It then opens .docx, .xlsx and .pptx files from your file manager.
Lossless editing
The goal: edit a Word, Excel or PowerPoint file here, save it in the same format, and send it to someone who uses Microsoft Office. It opens for them without an error or repair message, with your changes in place and everything else exactly as it was.
- What VibeOffice can't edit for now, it keeps. VBA macros, embedded objects, SmartArt, video and audio, ink, 3-D models, custom XML and Office's newer extensions are written back byte for byte. Content it does edit keeps its original names and IDs, so links, comments and animations still point where they did.
- Edits change only what you changed. Move or resize an object VibeOffice can't edit, and only its position changes. Set a shape's shadow, and its unsupported attributes stay.
- Each app's own features survive:
- Nothing lost silently. If a save would drop something you would miss, the Compatibility Checker will show a warning.
