Starting from Excel or Number

  • Start by converting your Excel file to OpenDocument. We recommend CloudConvert

  • Download a OpenDocument Editor: LibreOffice or OpenOffice. This is especially true if you want to have a fine control on the end graphical result.

General approach

  • Top-bottom display: think about the application in a web browser. People like to scroll in the vertical direction: top <> bottom. Organize your calculator elements accordingly.

  • Avoid background color: highlight cells using background color or borders. Let the background of your tabs. Later the background of the website where the calculator is embedded will apply.

  • Use mainstream fonts

Experts tips

  • Hide the data: having a large data set (example: for a VLOOKUP function)? Move the data into a separate tab and hide it. This way Appizy does not render as a visual element: it can reduce the size of your web-application by a factor 10 and speeds up dramatically the calculation.
