Signature

CALL atag.export.jgfFile(nodes, relationships, filename) YIELD value

• nodes: List of nodes (List<Node>)
• relationships: List of relationships (List<Relationship>)
• filename: Name of the output file (in the import folder) - must not contain path separators (String)
• Returns: Filename (value)

Example

Export a subgraph with APOC and write it as a JGF file:

MATCH (start:Person {name: 'Alice'})
CALL apoc.path.subgraphAll(start, {maxLevel:2}) YIELD nodes, relationships
CALL atag.export.jgfFile(nodes, relationships, 'myExport.json') YIELD value
RETURN value

The file myExport.json will be placed in the import folder and contains the graph in JGF format.

Features

• Exports nodes and relationships with all properties and labels.
• Supports various property types (String, Integer, Long, Double, Boolean, LocalDate).
• Filename must not contain path separators.

Typical Usage

• Export graph data for further processing or visualization in external tools.
• Integration with APOC procedures for flexible subgraph extraction and file export.
