"There's no better and easier data transformation tool out there"

4.5/5

What do you like best about Apache FreeMarker?

Freemarker has the least learning curve of all the transformation technologies. When compared with Xquery, Jsonpath, xpath etc. Freemarker is might weight and faster processing than the others. Combined with great built in functions and macros support and support for all the data structures of Java, I can't think of any other technology that comes even close to freemarker in this domain.

What do you dislike about Apache FreeMarker?

Though the documentation is pretty good, finding a function that does exactly what you need is a bit challenging. Also, the dateTime formatting libraries and their documentation could be improved.

There's no good IDE support. Very few plugins in eclipse and IntelliJ offer support for freemarker linting. Review collected by and hosted on G2.com.

What problems is Apache FreeMarker solving and how is that benefiting you?

I've used freemarker as a data transformation tool for JSON to XML and JSON to JSON transformations.

Handling some complex transformations are where freemarker shows its elegance. It's easy to write and debug transformations using freemarker.

Benefits are:

1) Support for all Java structures like map, set, lists etc

2) Very fast and light weight

3) Fast learning curve Review collected by and hosted on G2.com.
