JSON to SQL Converter

Turn JSON data into a SQL table and insert statements.

  • Free
  • No sign-up
  • Nothing is sent or stored
Column types are inferred from your data. Strings are escaped safely; review types before running.

The calculation happens instantly in your browser. The numbers you enter are not sent to our servers or saved.

How to use the JSON to SQL Converter

  1. Paste a JSON object or an array of objects.
  2. Choose the table name and database.
  3. Copy or download the SQL.

What does this tool do?

Each object becomes a row and each key a column. Column types are inferred from the values: integers, decimals, booleans, dates, timestamps, text, and JSON for nested objects.

Values are escaped (single quotes doubled), identifiers are quoted the way each database expects, and inserts are batched in groups of 100 rows. Everything runs in your browser; nothing you paste is uploaded.

Why use it?

  • Four SQL dialects.
  • Type inference.
  • Safe escaping.

Accuracy and limits

  • Always review inferred types — for example, IDs with leading zeros should stay as text.

Privacy

The calculation happens instantly in your browser. The numbers you enter are not sent to our servers or saved. There's no account to create and nothing to install.
