Use NeoMath and NeoChem in Word through the NeoMath tab on Windows, the Office add-in on Mac and the web, and the direct send shortcuts from the app.

On this page

There are three ways to work with Word, and they coexist:

Way Where What it is for
NeoMath tab on the ribbon Word for Windows create, edit, number and convert equations and structures without leaving Word
Direct send from the app NeoMath and NeoChem on Windows send the open equation to the Word cursor with a shortcut
Office add-in (side panel) Word for Mac and Word on the web insert, update and convert equations from the panel

NeoMath tab (Windows)#

The tab is installed with NeoMath. Each button opens the right app and returns the result to the document when you save.

Group Button What it does
Equation New equation opens NeoMath; when you save (Ctrl+S), the equation enters the document
Equation Edit equation opens the selected equation in NeoMath; when you save, it is replaced in place
Equation Numbered new display equation, numbered on the right
Equation Insert as Word equation, SVG image or PNG image (300 dpi); inline, display, numbered on the right or on the left
Chemistry New structure / Edit structure the same with NeoChem, for structures and reactions
Document Export all saves every equation of the document to a folder (EPS, SVG or PNG, plus MathML)
Document $…$ to equations turns every $…$ and $$…$$ into an equation
Document Equations to LaTeX turns Word equations into LaTeX text between $…$
Document Update numbering recalculates equation numbers and references
Convert All to Word / SVG / PNG equations converts every equation in the document
Convert Apply current style to images redraws NeoMath images with the preference chosen in NeoMath
Programs Open NeoMath, Open NeoChem, Help shortcuts to the apps
Buttons of the NeoMath tab in Word

Formats in the document#

  • Word equation (OMML): native, also editable in Word.
  • SVG image: vector; reopens in NeoMath to edit.
  • PNG image: 300 dpi.

Numbered equations use SEQ fields and bookmarks, so cross-references and Update fields work.

Direct send from the app#

With Word open on Windows, in NeoMath:

Shortcut Action
Ctrl+Enter sends the equation to the Word cursor
Ctrl+Shift+Enter updates the selected equation in Word
Ctrl+Shift+W brings the equation selected in Word into NeoMath

All three are in the shortcut profile and can be changed in atalhos.json. The editor’s context menu also has Send to Word.

From the command line#

PowerShell
neomath word inserir equacao.tex --modo nativa
neomath word inserir - --bloco --numerada direita
neomath word equacoes
neomath word exportar
neomath word converter-tex
neomath word atualizar-numeros

neomath word with no action shows help. --abrir starts Word if none is open.

Office add-in (Mac and web)#

The add-in is a side panel that inserts, updates and converts equations. LaTeX and MathML to Word equation translation gives the same result as the app.

  • Each equation lives in a content control tagged neomath:<id>.
  • Bring selected recovers exactly what was typed, including \ce{}, and Update selected swaps the content without losing the control.
  • The panel follows the Office theme (light or dark) and has chemistry shortcuts (\ce, \ox, \pu, \enthalpy).

Load in Word on the web#

  1. Get from Neo the address of the add-in hosted over HTTPS and the manifest.xml file.
  2. In Word on the web, open Insert › Add-ins › Upload My Add-in.
  3. Choose manifest.xml. The NeoMath panel appears on the ribbon.

In companies and schools, the Microsoft 365 administrator can distribute the add-in to everyone through the admin center.

NeoChem in Word#

NeoChem has its own bridge with Word: structures and reactions go in as SVG or PNG and reopen in NeoChem with the Edit structure button.
