From a Schema File

No database needed. DBSprout parses a schema file (or Django models) and generates data the same way it would from a live connection.

1. Parse the schema

SQL DDL

dbsprout init --file schema.sql

DBML

dbsprout init --file schema.dbml

Prisma

dbsprout init --file schema.prisma

Mermaid

dbsprout init --file schema.mmd

PlantUML

dbsprout init --file schema.puml

Add --dry-run to preview the parsed schema without writing dbsprout.toml or a snapshot:

dbsprout init --file schema.sql --dry-run

Django models

Introspect models directly from a Django project:

dbsprout init --django --django-apps myapp,billing

2. Generate as CSV or JSON

No database to insert into, so write files:

# CSV — one file per table, with headers
dbsprout generate --rows 500 --output-format csv

# JSON — one pretty-printed array per table
dbsprout generate --output-format json --seed 123

Output lands in ./seeds/ (override with --output-dir).

3. Validate

dbsprout validate

Schema Input — every supported format in detail
Output Formats — JSONL, Parquet, direct insert, UPSERT
