About this tool, tips & examples

What it does

The SQL INSERT Generator writes ready-to-run INSERT statements full of clearly synthetic data: give it a table name, a row count (up to 1,000), and optionally timestamp columns, and get a seed script for development and test databases. Deterministic by seed — the same settings always produce the same script, byte for byte.

Common use cases

  • Local development — populate a fresh schema with enough rows to make the app feel real.
  • Migration testing — consistent before-data for verifying transformations and rollbacks.
  • SQL teaching and demos — example tables students can create and query immediately.
  • Query examples — self-contained fixtures for bug reports and documentation (“run this, then the query misbehaves”).

Settings

  • Table name — the target table (validated to a safe identifier).
  • Rows — 1 to 1,000 INSERT rows.
  • Include timestamps — add created/updated-style columns.
  • Seed — identical seed + settings = identical script, so seeded databases match across the whole team.

Privacy note

SQL is generated locally in your browser and never uploaded — and the tool never connects to any database; you review and run the script yourself. Values are labeled synthetic: no real records, credentials, or personal data.

FAQ

Is it safe to run the output? In a development or test database, yes — but review generated SQL before executing anywhere, as you would any script. It’s INSERTs only; still, production is not the place.

Why deterministic seed scripts? “Works on my machine” often means “my seed data differs.” A committed seed + settings gives every developer and CI run the identical database starting state.

Need specific columns or realistic domains? Generate domain data with the dataset tools (Fake Users, Orders, Products) and export CSV for COPY/LOAD DATA — this tool is the quick INSERT-script path when any plausible rows will do.
