In order to replace the current formula plugin in Handsontable with the new engine, we'd need to add the lacking formulas. As of the 6th of February 2020, there are 247 functions to be added across 10 categories.

The complete formula reference is here: https://docs.google.com/spreadsheets/d/1jMvfY5DzMxmTiUTZB-8wwtMaKB2OqWEWqi-Ku1FogZE/edit#gid=1120069524
