Data Exports and Reports are really the same thing. They use the same syntax and tags. The only difference is that a Report shows on-screen (an/or can be printed), while a Data Export saves it’s output to a file.
So get the Report working to show the data you want, then worry about the formatting. As @JTRTech mentions, you need to apply a filter for the Entity Type. This comes after the first colon. This should work:
(ET=Customers)
The formatting is the part after the final colon where you choose your fields and delimiters, and is the easy part - you use commas (,) or semi-colons (;) to separate the fields instead of pipes (|).
