JSON to SQL Insert

Convert JSON to SQL Insert free, in seconds. Paste your data below, press Convert, then copy the result and run it against MySQL, PostgreSQL or SQLite. Everything runs in your browser, so nothing is ever uploaded.

JSON input

Paste your JSON below, then press Convert.

Tip: arrays of objects convert best. A single object becomes one row.
Used in the INSERT INTO clause.

Waiting for JSON input.

Private by design: conversion runs entirely in your browser with built-in code, so your data never leaves your device.

How this conversion works

Paste JSON into the input box and press Convert (or just keep typing, conversion happens as you type). The tool parses it with the browser's native JSON parser, then generates a single multi-row INSERT statement, quoting strings, passing numbers through and turning blanks into NULL. Conversion runs entirely in your browser with built-in code, so your data never leaves your device.

Running the SQL

The output is one multi-row INSERT statement, which loads faster than one statement per row. Strings are single-quoted with inner quotes doubled, numbers pass through unquoted, booleans become TRUE or FALSE, and empty values become NULL. Edit the Table name field before converting to target your real table; the name is sanitized to safe characters automatically.

JSON to SQL Insert FAQs

Why convert JSON to SQL INSERT?
INSERT statements are the universal way to seed a database: run the output in MySQL, PostgreSQL, SQLite or MariaDB to load exported data into a table in one step. It is handy for migrations, demos and test fixtures.
How is my JSON parsed?
With the browser's native JSON parser, so even large documents convert fast. An array of objects becomes one row per object, a single object becomes a single row, and nested values are flattened with dot notation (for example contact.city).
Can I change the table name?
Yes. Edit the Table name field above the output before pressing Convert. It defaults to my_table and is sanitized to letters, numbers, underscores and dollar signs.
How are values quoted?
Strings are single-quoted with inner quotes doubled, numbers pass through unquoted, booleans become TRUE or FALSE, and empty values become NULL. Everything goes into one multi-row INSERT statement for speed.
Is my data sent to a server?
No. conversion runs entirely in your browser with built-in code, so your data never leaves your device.
