Brief description
MathCell Helper is an independent browser-based prototype for capturing, displaying, saving and reusing mathematical formulas. Prototype 2.1 separates display formulas from executable spreadsheet formulas and adds a German/English interface, a light/dark switch and a compact information menu.
The application combines LaTeX for visible presentation with controllable spreadsheet-formula templates. Placeholders are assigned to cell references or fixed values and then generated for Excel, Google Sheets or Apple Numbers.
A small starter library is available directly in the browser. Users can save their own references locally, export them as JSON or CSV and import them again later. The application does not yet write directly into active spreadsheet cells; instead, it provides a controlled workflow for copying, pasting and exporting.
