Review the inferred column types before using a generated CREATE TABLE - this tool makes a reasonable guess from the JSON values, not a guarantee of your intended schema.

What Does This Tool Convert?

It takes a JSON array of objects (each object representing one row) and generates SQL INSERT statements for a table you name, with object keys becoming column names.

Why Use This Tool?

Useful when you have data as JSON (from an API response, a config file, or a JavaScript array) and need it seeded into a SQL database - a common step when setting up test/demo data.

How to Use It

Paste a JSON array of objects.
Enter a table name.
Optionally enable a CREATE TABLE statement inferred from the data's value types.
Copy the generated SQL.

Limitations

Inferred column types are a reasonable best guess (string, integer, boolean, and so on) based on the JSON values seen - always review and adjust for your actual schema requirements before running it against a real database.

Frequently Asked Questions

Column names come from the keys of the JSON objects. The optional CREATE TABLE statement guesses types from the values - review them before using it in production.

SQL columns hold single values, so nested objects or arrays cannot map directly to columns. Flatten them first or store them in a JSON column.

Yes. Single quotes inside strings are escaped, so values like O'Brien do not break the generated statements.
