Hi Connections ,
can anyone suggest how to do the data preprocessing techniques in neo4j
Hello @simsree9 
Why do you mean by preprocessing? If the objective is to clean or format some properties, it should be done before the ingestion in the database. If it's too create relationships based on a pattern, then it's fine.
