Use the correct delimiters
Write inline equations between single dollar signs and display equations between double dollar signs on separate lines. Code fences retain literal source instead of becoming equations unless they use the engine-supported math syntax.
Compare the mathematical structure
Fractions, roots, superscripts and subscripts should retain their structure in Word. A visually similar Unicode string is not equivalent to an editable equation; inspect a representative formula in the equation editor.
Keep a source copy
Save the Markdown alongside the DOCX. Editor-specific changes to OMML are not automatically reflected in the Markdown and conversion is not a round-trip synchronizer.
Check the equations in Word
Begin with a small document containing an inline expression and a displayed fraction, such as $x^2$ and a separate LaTeX fraction. Convert it, open the DOCX in Word and click the equation. Supported math is written as native Office Math objects, allowing equation editing rather than merely selecting a screenshot of the expression.
Inspect a denominator, a superscript and a symbol that appears in your real source. A converter can produce a valid DOCX while a particular mathematical command is unsupported or looks different in another editor. Test representative formulas before converting a long manuscript. Keep the Markdown source beside the output so corrections do not depend on reverse-engineering the Word document.
The conversion uses the pinned Markdown and math libraries; it is not a complete TeX engine. Custom macros, document classes and arbitrary packages do not become supported because their text appears inside math delimiters. Simplify unsupported notation or replace a complex diagram with a local image when that representation is suitable for your readers.
After opening the result, save a copy from the editor you expect collaborators to use. Check line wrapping, table width and equation placement again in that saved file. Different office applications can render the same document differently, so a native equation object establishes editability rather than guaranteeing identical layout across every editor and operating system.
