An EIF file is a standard text file, which contains one action per line. The variables on each line are tab delimited. Due to technicalities, and to ensure high quality, an EIF file can only contain a maximum of 1000 actions. If you need to process more than 1000 actions at once, you will need to split them up into multiple files, and import each EIF file separately.

A small example of an EIF file, which contains three actions, is shown below:
