Frequently Asked Questions

How does JSON to SQL INSERT work?

The tool parses your JSON array of objects and generates one INSERT statement per object. Column names come from object keys, and values are automatically quoted based on their type (strings get quotes, numbers don't, null becomes NULL).

What JSON format is supported?

The tool accepts a JSON array of objects, e.g. [{"name": "Alice", "age": 30}]. It also handles a single object (generates one INSERT) or an object containing an array (auto-detects the array).

Does it handle special characters?

Yes — single quotes in string values are escaped by doubling them (SQL standard). Nested objects and arrays are serialized to JSON strings.

Can I customize the table name?

The default table name is 'table_name'. You can change it in the generated output — just find-and-replace the table name in the SQL.

Is this converter free?

Yes — completely free, forever. No sign-up, no account, no usage limits.

Is my data safe?

All conversion happens locally in your browser using JavaScript. Your JSON is never uploaded to any server.
