Use Formatter to change number formats. You can modify numbers in three ways:

Currency: Convert numbers to currency formats.
Number: Localize numbers into different regional number format conventions.
Phone number: Standardize phone numbers into a specific format.

This is helpful when you need a different format in later steps in your Zap.

Number

This transform allows you to specify how numbers are grouped and where decimal points are placed (for example 1,234.56 into 1 234,56).

Click the Transform field dropdown menu and select Format Number.
In the Input field, map the field containing the number you want to style.
Click the Input Decimal Mark dropdown menu. Select which character should be used to separate the whole part of a number from its decimal part.

This transform allows you to format phone numbers with country codes and validate them against the selected country code (for example +1 (123) 456-7890).

Click the Transform field dropdown menu and select Format Phone Number.
In the Input field, map the field containing the phone number you want to style.

3. Test your action

Test your action to verify it is formatting the data correctly.

Click Test step.
The Data out tab will display the Output with the new formatted data.
If the new data is not what you expect, you can adjust the transform settings and retest the step again.

Once you’ve set up your Formatter action, you can use the results in further actions in your Zap.
