Operators Basics

Operators in Latenode are like formulas in spreadsheets: they take input data and return a result.

Using operators to modify data

You can use operators in almost any input field across nodes to transform data before sending it next:

• Build or modify text (replace ,concatenate, trim, case conversion)
• Do math and formatting
• Extract values from JSON/arrays
• Apply conditional logic (choose one value or another)

Using operators in routes

Routes use operators for filtering and branching. When operators are used in Route > Condition, the condition must evaluate to a boolean: TRUE or FALSE.

The result of any route filter is TRUE or FALSE

• If the filter condition is TRUE, the scenario execution continues through that route.
• If the filter condition is FALSE, that route is not selected and execution does not go there.

Fallback route

A fallback route triggers only if none of the outgoing routes from the node evaluates to TRUE.

How to test and debug any filter

You can test any route filter by copying the same formula into a separate Set Variables node in a neighboring branch.

This makes debugging easier because you can see:

• the input values used by the expression
• the final result of the filter as true/false in the node output

Example: copy the route condition into Set Variables and store it into a variable (e.g. test) — then check the output.
