Quick Answer
soffice.exe is safe. It's the LibreOffice Writer engine that opens, edits, and saves documents in LO, often spawning helper processes for rendering and spell checking to keep the UI responsive.
Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\LibreOffice\program\soffice.exe
Can I Disable?

Disabling may prevent opening documents, auto-save, and printing features. Writer won't start in Windows with a document opened and could affect file associations.
What is soffice.exe?
libreoffice-writer-exe (soffice.exe) is the main executable for LibreOffice Writer, the word processor that handles creation, formatting, and editing of text documents. It launches a primary window and may spawn additional workers for rendering, spell check, and plugin actions, depending on the document size and features used.
Writer uses a multi-component architecture where soffice.exe manages the UI, saves changes, and coordinates with internal modules for layout and formatting, enabling stable editing even with large documents.
Quick Fact: LibreOffice Writer can handle rich text, ODT and import DOCX, with a modular core that can start multiple background tasks to support real-time editing and autosave.
