What are Formulas?

Tomat's formula language has a lot to offer, with hundreds of functions quite similar to your favorite ones in Excel and SQL. Formulas can be as simple as a single number or as complex as a function call or mathematical formula.


  • Regular math operators: +, -, *,/,%

  • Comparison operators (evaluate to booleans): >, >=, <, <=, ==, !=, <>. These are used to compare two values and produce a boolean result (true or false).

  • Logical operators: ! , && , || (also support not, and, or variation). These operators are used to manipulate boolean values.

  • String concatenation operators: | . This is used to combine two or more strings into one.


  • Literal: represents a fixed value, like a number, "string", boolean (true, false), or a reference.

  • Unary: composed of a single operand and an operator. The operator can precede the operand -expression, !expression

  • Binary: consists of two operands and an operator expression operator expression.

  • Grouping: expressions can be grouped using parentheses (expression) to control the precedence of evaluation.


References in expressions can be made to:

  • Column by name: this allows for operations on specific columns in a data table.

  • REGEX Path to values in the specified columns: this allows for complex data manipulation using regular expressions.

  • Constants and enums: these can be used as parameters in functions.
