Power Automate (WDL) function

string — Power Automate (WDL) function reference

Convert to text.

Syntax

wdl

string(value)

wdl

string(variables('count'))

→ "42"

wdl

concat('Total: ', string(variables('orderTotal')))

→ "Total: 199.5"

Useful for logging a payload into a Compose action.

wdl

string(triggerBody())

→ A compact JSON string of the whole trigger body

string() on an object or array produces compact JSON text, not a friendly summary — pull specific properties instead for user-facing text.
string(null) returns the four-character text 'null', not an empty string — check for null before converting if you don't want the literal word appearing.
