-The aim of this project is to provide easy to use highlevel APIs to read the Office file formats by wrapping the POI APIs. In simple terms, the wrapper APIs would look similar to the [Jackson Project for XML and JSON](https://github.com/FasterXML/jackson), where the data can be mapped to a JAVA Bean and through the mapper APIs, the file data can directly be read as java objects.

-## Implementation Details
+##### Writing a List of objects defined as Map to file
+
+Similar to `Reader`, the `Writer` also supports Row data defined as `Map<String, Object>`. 
+This is to support the data that is not backed by a concrete bean Class definition
+
+Use `XlsWriter` for `.xls` files and `XlsxWriter` for `.xlsx` files.
