Install Dependencies

For loading XLS we’re using the Apache POI library, which works well with old and new Excel formats, but is quite large. That’s why we decided not to include it into the apoc jar, but make it an optional dependency.

These dependencies are included in apoc-xls-dependencies-4.1.0.11.jar, which can be downloaded from the releases page. Once that file is downloaded, it should be placed in the plugins directory and the Neo4j Server restarted.

Alternatively, you can download these jars from Maven Repository (putting them into plugins directory as well):

For XLS files:

poi-5.1.0.jar

Additional for XLSX files:
