How to use the JSON to SQL Insert Statements
Generate SQL INSERT statements in seconds:
1
Paste your JSON array
Paste a JSON array of objects. Each object becomes one INSERT row.
2
Set table name
Enter the target table name. Column names are derived from JSON keys.
3
Choose SQL dialect
Select MySQL, PostgreSQL, SQLite, or SQL Server for syntax-specific output.
4
Copy the SQL
Copy the generated INSERT statements and run them directly in your database client.

Frequently asked questions
Q:Which SQL databases are supported?
The tool generates syntax for MySQL, PostgreSQL, SQLite, and SQL Server. Each dialect has slight differences in quoting and value formatting that are handled automatically.
Q:How are different JSON value types mapped to SQL?
Strings become quoted VARCHAR values, numbers become unquoted integers or decimals, booleans become 1/0 or TRUE/FALSE depending on dialect, and null becomes SQL NULL.
Q:Can I insert multiple rows at once?
Yes — each object in your JSON array generates its own INSERT statement. You can run them all at once in any database client by executing the full output as a script.
