Math stays as LaTeX
This is the main limit to know. Equations are kept as their LaTeX source text, not converted into Word's equation format. Co-authors can read and edit them, and journals that accept LaTeX math in Word files can use them, but they are not typeset in the DOCX.
Finding the main file
In a .zip, Scissor Office looks for the main .tex file, follows its \input and \include commands into the other files and takes the pictures the project uses. The conversion is done by the same engine that Scissor LaTeX uses.
Getting a good result
Put the main file, the files it includes and its pictures into one .zip, keeping the folder layout the project uses, so the paths in \includegraphics and \input still match. After opening, check headings, lists and pictures, set the page size and margins the journal asks for, then save as DOCX. Keep the .tex files as your source: the DOCX is a copy for reviewers and editors.
Compiling a PDF
Documents turns LaTeX into an editable document; it does not compile it. To typeset the paper itself, use Scissor LaTeX.
Private by design
The project is unpacked and converted inside your browser tab. Your unpublished paper does not go to our servers.
