How do I convert JSON to SQL CREATE TABLE and INSERT statements?

Paste a JSON array of objects into AnyTool and it generates SQL CREATE TABLE and INSERT statements for MySQL, PostgreSQL, SQLite, SQL Server, or Oracle. Types are inferred across all rows with correct quoting and escaping, in real time, all in your browser with no upload.

  • CREATE TABLE + INSERT, CREATE only, or INSERT only
  • MySQL, PostgreSQL, SQLite, SQL Server, and Oracle dialects
  • All-row type inference with correct quoting and escaping
  • Batch inserts, copy, and .sql download
  • 100% in-browser — no upload, no row caps

What is

JSON to SQL

Converting JSON to SQL turns a JSON array of objects into database statements — a CREATE TABLE that defines columns and types inferred from the data, plus INSERT statements that load the rows — with dialect-specific identifier quoting, type mapping, and value escaping.

Frequently Asked Questions

Yes — types are inferred by scanning every row, not just the first.

It scans all rows to widen types correctly (for example mixed int and float become DECIMAL), detects ISO dates as DATE/DATETIME, and keeps a column nullable when values are missing, avoiding the broken imports that first-row-only tools produce.

MySQL, PostgreSQL, SQLite, SQL Server, and Oracle.

You can pick any of MySQL, PostgreSQL, SQLite, SQL Server, or Oracle, and the output adapts identifier quoting (backticks, double quotes, or brackets), boolean types, auto-increment syntax, and JSON column types per dialect.

It is free and your JSON is converted locally — nothing is uploaded.

Unlike server-side converters with signup and row limits, this runs entirely client-side with no row or size caps beyond your browser memory, so your data stays private and it works offline.

Detailed Explanation

Methodology

How JSON to SQL Conversion Works

AnyTool converts a JSON array of objects into SQL CREATE TABLE and INSERT statements for MySQL, PostgreSQL, SQLite, SQL Server, or Oracle. Column types are inferred by scanning all rows — widening mixed numerics to DECIMAL, detecting ISO dates, and keeping columns nullable when values are missing — and each dialect gets correct identifier quoting (backticks, double quotes, or brackets), boolean and auto-increment syntax, and JSON column types. Single quotes are escaped, numerics stay unquoted, and inserts can be batched.

  • MySQL, PostgreSQL, SQLite, SQL Server, Oracle
  • All-row type inference with NULL widening
  • Correct per-dialect quoting and escaping

Privacy & Security

Privacy and Offline Use

Parsing and SQL generation run client-side (in a Web Worker for large arrays) with no upload and no runtime CDN, so data stays private with no row or size caps beyond browser memory, and the tool works offline after first load.
