+== Parquet file support
+Starting with Neo4j 5.24, Neo4j provides support for the Parquet file format in a public beta version.
+The additional parameter `--input-type [csv|parquet]` was introduced to explicitly tell the importer to use either CSV or Parquet.
+Its value defaults to CSV if it is not defined.
+
+Most of the parameters that can be used to configure the import are also valid for the Parquet format.
+There are indicators in the parameter overview to point out which parameters are supported.
+
+The xref:tools/neo4j-admin/neo4j-admin-import.adoc#import-tool-examples[examples] for CSV can also be used with Parquet.
