Web & Developer
Convert JSON objects and arrays into production SQL INSERT statements. Supports PostgreSQL, MySQL, and SQLite dialects with automatic quote escaping, multi-row bulk batching, and conflict handling.

📋How to Generate SQL INSERT from JSON

  1. 1. Paste Source JSON: Paste an array of JSON objects or a single JSON record into the input area or select a preset.
  2. 2. Configure Table & Dialect: Set your destination database table name, select your SQL dialect (PostgreSQL, MySQL, SQLite), and choose single or bulk batching.
  3. 3. Generate & Copy SQL: Click Generate SQL INSERT to inspect the formatted SQL queries and copy them to your clipboard.

⚙️Data Type Coercion & SQL Injection Protection

Converting loose JSON data into relational SQL requires rigorous type handling, proper quote escaping, and dialect-specific formatting.

• Single Quote Escaping: Safely doubles single quotes (e.g. O'Reilly to 'O''Reilly') to prevent SQL syntax breakage.
• Dialect Identifier Quoting: Applies double quotes ("col") for PostgreSQL/SQLite and backticks (`col`) for MySQL/MariaDB.
• Boolean & NULL Handling: Serializes booleans as native TRUE/FALSE for PostgreSQL and 1/0 for MySQL/SQLite, mapping missing values to NULL.
• Multi-Row Bulk Batching: Combines multiple rows into a single VALUES (...), (...) block to maximize database ingestion throughput.

Compatible with all relational database engines and command-line clients including psql, mysql-cli, and sqlite3.

💡Practical Use Cases

  • Database Seeding & Fixtures: Convert mock JSON test fixtures into SQL seeds for staging or development databases.
  • Data Migration: Transform exported NoSQL documents into relational tabular records for SQL databases.
  • Manual Data Correction: Rapidly generate INSERT or UPSERT statements from webhook debug payloads.
100% Client-Side Privacy Guarantee:Your JSON data and generated SQL queries are processed strictly in your local browser sandbox. Zero data is ever sent to external servers.
