Custom Formulas

Custom formulas allow you to use Excel-like expressions to perform advanced calculations or to apply custom logic.

Writing Formulas

Our Formula editor will guide you through writing any formulas using its built-in autocomplete and documentation.

You can also use the keyboard to navigate the autocompletion suggestions and hit Enter or Tab to accept them.

Custom formulas can reference any other existing column using the prop("Column name") function, as well as variable blocks using the variable("Variable name") function.


Simple calculations

  • Adding together two numeric columns: add(prop("Column A"), prop("Column B"))
  • Multiplying a column by a constant number: add(prop("Column A"), 25)
  • Subtracting two dates (and getting a time interval): sub(prop("End date"), prop("Start date"))

Conditional logic

  • Outputing 0 if Status is equal to active, and otherwise 1: case(eq(prop("Status"), "active"), 0, 1)

Date operations

  • Getting the end of the month based on a Date column called Some Date: end_of_month(prop("Some Date"))
  • Getting the number of minutes between two Date columns: date_diff(prop("End date"), prop("Start date"), "minute")
