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 chunks → neo4j-document-import-skill
Live application writes (MERGE/CREATE in app code) → neo4j-cypher-skill
neo4j-admin backup/restore/config → neo4j-cli-tools-skill
GDS algorithm projection from existing graph → neo4j-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

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.
Verify APOC if using apoc. procedures*:
```
RETURN apoc.version();
```
If fails → APOC not installed. Use plain LOAD CSV instead.
Confirm target is PRIMARY (not replica):
```
CALL dbms.cluster.role() YIELD role RETURN role;
```
If role ≠ PRIMARY → stop. Redirect write to PRIMARY endpoint.
Count source file rows before import (catch encoding issues early):
```
wc -l data/persons.csv    # Linux/macOS
```

Verify UTF-8 encoding — LOAD CSV requires UTF-8. Re-encode if needed:

file -i persons.csv       # Check encoding
iconv -f latin1 -t utf-8 persons.csv > persons_utf8.csv

LOAD CSV Patterns

Basic node import with type coercion and null handling

CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///persons.csv' AS row
CALL (row) {
  MERGE (p:Person {id: row.id})
  ON CREATE SET
    p.name       = row.name,
    p.age        = toIntegerOrNull(row.age),
    p.score      = toFloatOrNull(row.score),
    p.active     = toBoolean(row.active),
    p.born       = CASE WHEN row.born IS NOT NULL AND row.born <> '' THEN date(row.born) ELSE null END,
    p.createdAt  = datetime()
  ON MATCH SET
    p.updatedAt  = datetime()
} IN TRANSACTIONS OF 10000 ROWS
  ON ERROR CONTINUE
  REPORT STATUS AS s
RETURN s.transactionId, s.committed, s.errorMessage

Null/empty-string rules:

CSV missing column → null (safe)
CSV empty string "" → stored as "" not null — use nullIf(row.x, '') to convert
toInteger(null) throws → always use toIntegerOrNull()
toFloat(null) throws → always use toFloatOrNull()
Neo4j never stores null properties — they are silently dropped on SET

Relationship import (nodes must exist first)

CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///knows.csv' AS row
CALL (row) {
  MATCH (a:Person {id: row.fromId})
  MATCH (b:Person {id: row.toId})
  MERGE (a)-[:KNOWS {since: toIntegerOrNull(row.year)}]->(b)
} IN TRANSACTIONS OF 5000 ROWS
  ON ERROR CONTINUE
  REPORT STATUS AS s

Always import ALL nodes before ANY relationships — MATCH fails on missing nodes.

Tab-separated or custom delimiter

CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///data.tsv' AS row FIELDTERMINATOR '\t'
CALL (row) { MERGE (p:Person {id: row.id}) }
IN TRANSACTIONS OF 10000 ROWS ON ERROR CONTINUE

Compressed files (ZIP / gzip — local files only)

LOAD CSV WITH HEADERS FROM 'file:///archive.csv.gz' AS row ...

Cloud storage (Enterprise Edition)

Scheme	Example
AWS S3	`s3://my-bucket/data/persons.csv`
Google Cloud Storage	`gs://my-bucket/persons.csv`
Azure Blob	`azb://account/container/persons.csv`

Useful built-in functions inside LOAD CSV

linenumber()   // current line number — use as fallback ID
file()         // absolute path of file being loaded

CALL IN TRANSACTIONS — Full Reference

Syntax

CALL (row) {
  // write logic
} IN [n CONCURRENT] TRANSACTIONS
  [OF batchSize ROW[S]]
  [ON ERROR {CONTINUE | BREAK | FAIL | RETRY [FOR duration SECONDS] [THEN {CONTINUE|BREAK|FAIL}]}]
  [REPORT STATUS AS statusVar]

ON ERROR modes

Mode	Behavior	Use when
`ON ERROR FAIL`	Default. Rolls back entire outer tx on first error	All-or-nothing strict import
`ON ERROR CONTINUE`	Skips failed batch, continues remaining batches	Resilient bulk load — track errors via REPORT STATUS
`ON ERROR BREAK`	Stops after first failed batch; keeps completed work	Semi-strict: stop early, keep successful batches
`ON ERROR RETRY`	Exponential backoff retry (default 30s) + fallback	Concurrent writes with deadlock risk

ON ERROR CONTINUE/BREAK → outer transaction succeeds even if inner batches fail. ON ERROR FAIL → cannot be combined with REPORT STATUS AS.

CONCURRENT TRANSACTIONS (parallel batches)

CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///large.csv' AS row
CALL (row) {
  MERGE (p:Person {id: row.id}) SET p.name = row.name
} IN 4 CONCURRENT TRANSACTIONS OF 5000 ROWS
  ON ERROR RETRY FOR 30 SECONDS THEN CONTINUE
  REPORT STATUS AS s

Use CONCURRENT for read-heavy MERGE on non-overlapping key spaces. Risk: deadlocks on overlapping writes → combine with ON ERROR RETRY.

REPORT STATUS columns

Column	Type	Meaning
`s.started`	BOOLEAN	Batch transaction started
`s.committed`	BOOLEAN	Batch committed successfully
`s.transactionId`	STRING	Transaction ID
`s.errorMessage`	STRING or null	Error detail if batch failed

Batch size guidance

Row count	Recommended batch size	Notes
< 100k	10 000	Default is fine
100k – 1M	10 000 – 50 000	Monitor heap; increase if fast
1M – 10M	50 000 – 100 000	Enable CONCURRENT if CPUs available
> 10M online	50 000	Consider neo4j-admin import instead
Relationship import	5 000	Lower — each batch does 2x MATCH

neo4j-admin import (Offline Bulk Load)

Fastest method: ~3 min for 31M nodes / 78M rels on SSD. DB must be stopped or non-existent.

Command structure

neo4j-admin database import full \
  --nodes=Person="persons_header.csv,persons.csv" \
  --nodes=Movie="movies_header.csv,movies.csv" \
  --relationships=ACTED_IN="acted_in_header.csv,acted_in.csv" \
  --relationships=DIRECTED="directed_header.csv,directed.csv" \
  --delimiter=, \
  --id-type=STRING \
  --bad-tolerance=0 \
  --threads=$(nproc) \
  --high-parallel-io=on \
  neo4j

Dry run (2026.02+) — validate without writing:

neo4j-admin database import full --dry-run ...

Node header file format

# persons_header.csv
personId:ID,name,born:int,score:float,active:boolean,:LABEL

# persons.csv (data file — no header row)
p001,Alice,1985,9.2,true,Person
p002,Bob,1990,7.1,false,Person

Field	Meaning
`:ID`	Unique ID for relationship wiring (not stored as property by default)
`:ID(Group)`	Scoped ID space — use when node types share IDs
`:LABEL`	One or more labels; semicolon-separated: `Person;Employee`
`prop:int`	Typed property; types: `int long float double boolean byte short string`
`prop:date`	Temporal: `date localtime time localdatetime datetime duration`; Parquet `INTERVAL` columns import as `DURATION` [2026.07+]
`prop:int[]`	Array — semicolon-separated values in cell: `1;2;3`
`prop:vector`	Float vector (2025.10+) — semicolon-separated coordinates in CSV; imports directly from native Parquet list types [2026.06+]

Relationship header file format

# acted_in_header.csv
:START_ID(Person),:END_ID(Movie),role,:TYPE

# acted_in.csv
p001,tt0133093,Neo,ACTED_IN
p002,tt0133093,Morpheus,ACTED_IN

:START_ID / :END_ID must reference the same :ID group as the node files.

Key flags

Flag	Default	Notes
`--delimiter`	`,`	Single-byte UTF-8 char, `TAB`, `\ID`, or `U+XXXX`; newline chars rejected [2026.07+]
`--vector-delimiter`	`;`	Separates `prop:vector` coordinates; must differ from `--delimiter` and `--quote` [enforced 2026.06+]
`--id-type`	`STRING`	`STRING \| INTEGER \| ACTUAL`
`--bad-tolerance`	`-1` (unlimited, changed 2025.12)	Set `0` for strict prod imports
`--threads`	CPU count	Set explicitly on shared hosts
`--max-off-heap-memory`	90% RAM	Reduce if other services share host
`--high-parallel-io`	`off`	Set `on` for SSD/NVMe
`--format`	`standard`	`block` for >34B nodes/rels
`--overwrite-destination`	false	Required if DB already exists
`--dry-run`	false	2026.02+ — validate without writing

Schema file (--schema) [Enterprise, block format]

Pass a Cypher file with CREATE CONSTRAINT / CREATE INDEX statements; executed automatically after import completes. Constraints are created first (correct order enforced). File paths can be local or remote (s3://, gs://, https://).

neo4j-admin database import full \
  --format=block \
  --schema=schema.cypher \
  --nodes=Person="persons_header.csv,persons.csv" \
  neo4j

// schema.cypher
CREATE CONSTRAINT person_id IF NOT EXISTS FOR (n:Person) REQUIRE n.id IS UNIQUE;
CREATE CONSTRAINT movie_id  IF NOT EXISTS FOR (n:Movie)  REQUIRE n.id IS UNIQUE;
CREATE RANGE INDEX person_email IF NOT EXISTS FOR (n:Person) ON (n.email);
CREATE TEXT  INDEX movie_title  IF NOT EXISTS FOR (n:Movie)  ON (n.title);

For incremental import, DROP CONSTRAINT / DROP INDEX are also supported [2025.02+] — used to remove indexes before the merge pha

## LOAD CSV Patterns

### Basic node import with type coercion and null handling

```cypher
CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///persons.csv' AS row
CALL (row) {
  MERGE (p:Person {id: row.id})
  ON CREATE SET
    p.name       = row.name,
    p.age        = toIntegerOrNull(row.age),
    p.score      = toFloatOrNull(row.score),
    p.active     = toBoolean(row.active),
    p.born       = CASE WHEN row.born IS NOT NULL AND row.born <> '' THEN date(row.born) ELSE null END,
    p.createdAt  = datetime()
  ON MATCH SET
    p.updatedAt  = datetime()
} IN TRANSACTIONS OF 10000 ROWS
  ON ERROR CONTINUE
  REPORT STATUS AS s
RETURN s.transactionId, s.committed, s.errorMessage
```

Null/empty-string rules:
- CSV missing column → `null` (safe)
- CSV empty string `""` → stored as `""` **not** `null` — use `nullIf(row.x, '')` to convert
- `toInteger(null)` throws → always use `toIntegerOrNull()`
- `toFloat(null)` throws → always use `toFloatOrNull()`
- Neo4j never stores `null` properties — they are silently dropped on SET

### Relationship import (nodes must exist first)

```cypher
CYPHER 25
LOAD CSV WITH HEADERS FROM 'file:///knows.csv' AS row
CALL (row) {
  MATCH (a:Person {id: row.fromId})
  MATCH (b:Person {id: row.toId})
  MERGE (a)-[:KNOWS {since: toIntegerOrNull(row.year)}]->(b)
} IN TRANSACTIONS OF 5000 ROWS
  ON ERROR CONTINUE
  REPORT STATUS AS s
```

Always import ALL nodes before ANY relationships — MATCH fails on missing nodes.

CREATE RANGE INDEX person_email IF NOT EXISTS FOR (n:Person) ON (n.email);
CREATE TEXT  INDEX movie_title  IF NOT EXISTS FOR (n:Movie)  ON (n.title);
```

For incremental import, `DROP CONSTRAINT` / `DROP INDEX` are also supported [2025.02+] — used to remove indexes before the merge pha

Copier ne signifie ni installer ni réussir une exécution. Vérifiez dépendances, coûts API et autorisations.

Les outils sont des indications de métadonnées, pas une compatibilité testée. Les prompts sont des suggestions.

Commencer par une petite tâche

1Lisez la source et confirmez entrées, résultats, dépendances et permissions.
2Demandez un plan à l’agent. Approuvez la configuration et les coûts avant un test isolé.
3Vérifiez résultats et fichiers modifiés. Signalez uniquement ce qui a été exécuté et conservez la révision source.

Vérifiez les dépendances, clés API et frais externes dans la source. Un dépôt public ne rend pas tous les services gratuits.
