Import Neo4j Nodes Data to Power BI. This power query uses the default HTTP API to get nodes only data from Neo4j.

Neo4jNodesTemplate.pq

// This Power Query script connects to Neo4j and runs a Cypher query that returns node objects.
// Get Nodes
let 
    //Enter the base URL for the Neo4j Server
    __Neo4jURL = "http://localhost:7474", 
    // Enter the name of the database in Neo4j
    __Neo4jDatabase = "blogs", 
    // Enter the username for database access in the Neo4j database
    __Username = "neo4j", 
    // Enter the user password for databases in the Neo4j database
    __Password = "demo", 
    // Enter a Cypher Query returning full nodes.
    __CypherQuery = "MATCH (n:Article) RETURN n", 
    // This step combines several steps to simplify and reduce the steps in Power Query to return data from Neo4j.
