2 -In this microlearning, we’ll cover how to add a header line to a flat-file output in eMagiz. A header line is the first row in your CSV file, defining the names of the columns for clarity. We’ll walk through the steps to configure this in your output flow, ensuring that your external systems receive data with properly labeled columns. By the end of this lesson, you'll know how to set up and manage header lines to meet your data formatting requirements.
2 +In this microlearning, we will learn how you can define a header line in which you specify the naming of the various columns. Some external systems require a header line when you supply them with data via a flat file that is placed somewhere.
