Interactive code blocks
An interactive code block turns placeholders in a code sample into a small form. Fill in the fields and your values are substituted into the code below, ready to copy. Nothing is sent anywhere; the code is assembled in your browser.
Import a CSV into the graph
Generated Cypher
// Create a uniqueness constraint for :{{label}} nodes
CREATE CONSTRAINT {{constraintName}} IF NOT EXISTS
FOR (n:{{label}})
REQUIRE n.{{keyProperty}} IS UNIQUE;
// Import nodes from a CSV file
LOAD CSV WITH HEADERS FROM '{{csvUrl}}' AS row
MERGE (n:{{label}})
SET n.{{keyProperty}} = row.id, n.name = row.name;{
"groups": [
{ "legend": "Schema", "fields": ["label", "constraintName", "keyProperty"] },
{ "legend": "Data source", "fields": ["csvUrl"] }
],
"fields": {
"label": { "label": "Node label", "description": "The label to apply to each imported node.", "default": "Person", "pattern": "[A-Za-z0-9_]" },
"constraintName": { "label": "Constraint name", "description": "A name for the uniqueness constraint.", "default": "person_id", "pattern": "[A-Za-z0-9_]" },
"keyProperty": { "label": "Key property", "description": "The property that uniquely identifies each node.", "default": "id", "pattern": "[A-Za-z0-9_]" },
"csvUrl": { "label": "CSV URL", "description": "The location of the CSV file to import.", "placeholder": "https://example.com/data.csv" }
}
}Empty fields keep their placeholder (or default) until you type. The copy button copies whatever the code block currently shows.
