Frequently Asked Questions (FAQ)

Does the calculator work in Open Office / Libre Office / anything other than Microsoft Excel?

Each calculator has a macro-free version, which should work in some of the other spreadsheet programs (generally those which support Excel functions, such as Open Office). However, I can’t provide support or do custom adjustments for the spreadsheets to work with software other than Microsoft Excel.

I have an older version of Excel. Does the calculator work in Excel 2003, 2002…?

Yes. All the calculators work in all Excel versions back to Excel 97. For some older versions of Excel you will need to use a specific version of the calculator due to some changes and incompatibility between functions and VBA code. Detailed instructions are available on the individual calculator pages and in the pdf guides.

I have bought the calculator, but not received the download.
