A guide for importing structured files such as CSV, JSON, or Parquet into Neo4j, a graph database.

In plain words
What is it for?
Use it to import data online or offline, batch-create nodes and relationships, migrate relational data into a graph, and verify constraints, indexes, and counts.
Why use it?
It helps choose between regular and bulk loading methods, handle large imports safely, and check that nodes and relationships were loaded correctly.

    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neo4j-import-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Neo4j Import Skill

When to Use

  • Importing CSV, JSON, or Parquet files into Neo4j
  • Batch-upserting nodes and relationships (UNWIND + CALL IN TRANSACTIONS)
  • Migrating relational data (SQL → graph)
  • Bulk-loading large datasets offline (neo4j-admin import)
  • Choosing between online (Cypher) and offline (admin) import methods
  • Verifying import completeness (counts, constraints, index states)

When NOT to Use

  • Unstructured docs, PDFs, vector chunksneo4j-document-import-skill
  • Live application writes (MERGE/CREATE in app code)neo4j-cypher-skill
  • neo4j-admin backup/restore/configneo4j-cli-tools-skill
  • GDS algorithm projection from existing graphneo4j-gds-skill

Method Decision Table

Dataset size DB state Source Method
Any size Online CSV (Aura or local) LOAD CSV + CALL IN TRANSACTIONS
< 1M rows Online List/API response UNWIND + CALL IN TRANSACTIONS
> 10M rows Offline (local/self-managed) CSV / Parquet neo4j-admin database import full
Any size Online APOC available apoc.periodic.iterate + apoc.load.csv
Any size Online JSON/API apoc.load.json or driver batching
Incremental delta Offline (Enterprise) CSV neo4j-admin database import incremental

Aura: only https:// URLs — no file:///. Use neo4j-admin import only on self-managed.


Pre-Import Checklist

Run in this exact order — skipping causes hard-to-debug duplicates or missed index usage:

Constraints BEFORE import. Additional indexes AFTER import.

  • Constraints create implicit RANGE indexes used by MERGE during load + enforce uniqueness
  • Additional non-unique indexes (TEXT, RANGE on non-key props, FULLTEXT) created after load — Neo4j populates them async from the committed data; poll populationPercent until 100%
  • Creating extra indexes before import slows every write during load with no benefit
  1. Create uniqueness constraints (enables index used by MERGE):
    CREATE CONSTRAINT IF NOT EXISTS FOR (n:Person) REQUIRE n.id IS UNIQUE;
    CREATE CONSTRAINT IF NOT EXISTS FOR (n:Movie)  REQUIRE n.movieId IS UNIQUE;
    

    Neo4j 2026.06+ (Enterprise/Aura, GA): ALTER CURRENT GRAPH TYPE SET { … } replaces all individual constraint statements with a single declarative block. See neo4j-cypher-skill/references/graph-type.md. Use individual CREATE CONSTRAINT on Community Edition or pre-2026.02.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
