JSON → SQL INSERT

Convert JSON arrays to SQL INSERT statements — fully in-browser

Input JSON

SQL Output

CREATE TABLE IF NOT EXISTS `users` (
  `id` INTEGER,
  `name` TEXT,
  `email` TEXT,
  `age` INTEGER
);

INSERT INTO `users` (`id`, `name`, `email`, `age`) VALUES (1, 'Alice', '[email protected]', 30);
INSERT INTO `users` (`id`, `name`, `email`, `age`) VALUES (2, 'Bob', '[email protected]', 25);
INSERT INTO `users` (`id`, `name`, `email`, `age`) VALUES (3, 'Charlie', NULL, 35);

About the JSON to SQL Converter

This tool converts JSON to SQL insert statements for MySQL, PostgreSQL or SQLite. It infers column types from the data, escapes string values and can emit a matching CREATE TABLE, all without the JSON leaving your browser.

Convert JSON to SQL when data needs to land in a database and writing the INSERTs by hand is not worth the time — seeding a development database, loading fixtures, or importing an API response into a reporting table.

Types are inferred from the values so the generated schema is sensible rather than everything as TEXT: integers become integer columns, decimals become numeric, true/false becomes boolean, and null stays null instead of the string "null". String values are escaped, so an apostrophe in a name does not end the statement early.

Dialect matters for quoting and types, so pick MySQL, PostgreSQL or SQLite before generating. Everything runs in your browser, which means production data can be converted without handing it to a third party.

How to use the JSON to SQL Converter

  1. Paste your JSON. Provide a JSON array of objects — one object per row.
  2. Choose the dialect. Pick MySQL, PostgreSQL or SQLite so quoting and types match your database.
  3. Set the table name. Name the target table the statements should insert into.
  4. Copy the SQL. Copy the generated INSERT statements, and the CREATE TABLE if you need it.

Frequently asked questions

Which SQL dialects are supported?

MySQL, PostgreSQL and SQLite. Choose one before generating so quoting and column types match your database.

Are column types detected automatically?

Yes. Integers, decimals, booleans and nulls are inferred rather than everything being emitted as TEXT.

Are string values escaped?

Yes. Quotes inside values are escaped so an apostrophe in a name cannot break the statement.

Can it generate the CREATE TABLE too?

Yes. A matching CREATE TABLE can be emitted alongside the INSERT statements.

Is my JSON uploaded anywhere?

No. Conversion runs in your browser, so the data never leaves your machine.
