This is so essential that I was surprised it wasn’t already supported. Some of the ways I’ve used it in Notion:
- progress bars, like percentage of completed tasks within an epic
- formatting raw columns into display columns
- date manipulation (like calculating next due date based on last done date)
- converting dates to durations (which update dynamically with a now() value)
- combining multiple columns into a single score value
- combining multiple columns into a single column that can then be used to filter a view
- unit conversions (F to C, in to cm, etc)
- and of course, simple accounting calculations
Really opens things up. This and support for Mermaid.js are my biggest reasons I can’t move from Notion yet.
