An Excel Add-In for chemistry calculations

Basic chemistry calculations in Excel

 

Already for years I use Excel for calculations, simulations and scientific graphics. As a chemical engineer  I missed however basic chemistry functionality in this spreadsheet.

 

That is why I developed this add-in. It provides Excel with the necessary functions to do basic chemistry calculations!

 

This Add-In lets you use chemical formulae in Excel spreadsheets and calculate properties like molecular weight, reaction coefficients, percent composition,... Reactions and chemical abbreviations can be saved for later use and organic molecules can be pictured using their SMILES notation.

It also provides a menu for quick calculations in predefined user forms. It includes average atomic weights and an extensive list of isotope weights for calculations. As such it allows to calculate compositions and reactions with specific isotopes instead of average atomic weights. Some specific functions for mass spectroscopy are also included.

It comes as an executable file which does not need installation, so you can also use it when you have no administrator rights on your computer.
