JSON to SQL Converter
Convert a JSON array of objects into SQL INSERT statements, with an optional CREATE TABLE statement inferred from the data.
Paste a JSON array of objects and a table name - this tool generates matching INSERT statements, with an optional CREATE TABLE based on the data's shape.
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.
