JSON to SQL INSERT

Runs locally in your browser. Nothing leaves your device.

Convert JSON objects and object lists to SQL INSERT statements directly in the browser.

Input

Check table structure, data types, constraints, and transaction behavior before use.

Output

Paste valid JSON to generate SQL.

How it works

  1. 1

    Paste the JSON

    Paste valid JSON with objects or an array.

  2. 2

    Set the dialect, table, and options

    Choose the SQL dialect, target table, batch size, missing-value strategy, and transaction.

  3. 3

    Copy or download the SQL

    Copy the generated INSERT statements or download them as a .sql file.

Good to know

The JSON to SQL INSERT generator converts JSON objects or arrays into INSERT statements directly in your browser, matching the chosen SQL dialect for identifier quoting and boolean/unicode literals. A batch size controls how many rows are bundled per INSERT statement — important since SQL Server caps at 1,000 rows per statement.

Schema and table names accept only letters, numbers, and underscores, missing properties can be treated as NULL, DEFAULT, or an error, and statements can optionally be wrapped with BEGIN and COMMIT. Important: the generated SQL is not executed — review table structure, data types, constraints, and transaction behavior before use.

Typical use cases

Generate test data for a development database from JSON

Convert a JSON array of test records into INSERT statements for the matching target table, in the respective database's dialect.

Split a large dataset into SQL Server-compatible batches

Limit the batch size to a maximum of 1,000 rows per statement when the target is SQL Server, to respect its statement limit.

Tips for better results

Deliberately set missing values to NULL or DEFAULT

Choose DEFAULT instead of NULL when the target table provides sensible default values for missing properties via column definitions.

Enable transactions for atomic imports

Wrap the statements with BEGIN and COMMIT so a failed import doesn't leave the target table in an inconsistent state.

Features

  • SQL dialect selection

    Sets identifier quoting and boolean/unicode literals for the target database.

  • Configurable batch size

    Bundle rows per INSERT statement, taking SQL Server's 1,000-row limit into account.

  • No SQL is executed

    The tool only generates text; there is no database connection and nothing is executed.

Frequently asked questions

Is the generated SQL executed?

No. The tool only generates text without a database connection; review table structure and constraints before using it yourself.

How many rows fit in one INSERT statement?

This can be set via the batch size; SQL Server is limited to a maximum of 1,000 rows per statement.
