When working with multiple apps, marketers often encounter issues with date and time formats to avoid app scheduling conflicts and keep their team on the same page. To solve this problem, Zapier's built-in Formatter tool can be used to transform data into a uniform format. A formatter step can change dates and times by adding or subtracting time, comparing dates, or transforming the format of the timestamp received from an app. The process involves setting up a trigger, selecting the Date/Time action in the formatter step, and specifying the desired date/time format. Once set up, the formatter step will automatically transform the data for you every time your Zap runs.
