JavaScript Object to SQL — Before & After Example

Before (JavaScript Object Input)
const data = [
  {
    id: 1,
    name: 'Alice Johnson',
    email: 'alice@example.com',
    role: 'admin',
    active: true,
    score: 98.5,
    address: {
      city: 'Berlin',
      country: 'DE',
    },
  },
  {
    id: 2,
    name: 'Bob Smith',
    email: 'bob@example.com',
    role: 'editor',
    active: false,
    score: 87,
    address: {
      city: 'Austin',
      country: 'US',
    },
  },
  {
    id: 3,
    name: 'Chiara Rossi',
    email: 'chiara@example.com',
    role: 'viewer',
    active: true,
    score: 91.25,
    address: {
      city: 'Milan',
      country: 'IT',
    },
  },
];

export default data;
After (SQL Output)
CREATE TABLE my_table (
  id INTEGER,
  name VARCHAR(255),
  email VARCHAR(255),
  role VARCHAR(255),
  active BOOLEAN,
  score REAL,
  "address.city" VARCHAR(255),
  "address.country" VARCHAR(255)
);

INSERT INTO my_table (id, name, email, role, active, score, "address.city", "address.country") VALUES (1, 'Alice Johnson', 'alice@example.com', 'admin', TRUE, 98.5, 'Berlin', 'DE');
INSERT INTO my_table (id, name, email, role, active, score, "address.city", "address.country") VALUES (2, 'Bob Smith', 'bob@example.com', 'editor', FALSE, 87, 'Austin', 'US');
INSERT INTO my_table (id, name, email, role, active, score, "address.city", "address.country") VALUES (3, 'Chiara Rossi', 'chiara@example.com', 'viewer', TRUE, 91.25, 'Milan', 'IT');

Frequently Asked Questions: JavaScript Object to SQL

How do I convert JavaScript Object to SQL online without uploading sensitive files? ▾

Paste your JavaScript Object data or drag and drop a .js file into the converter above. ZeroUpload parses JavaScript Object and serializes SQL 100% inside your browser RAM using local JavaScript—no bytes are ever sent to an external server.

How are nested objects or tabular columns mapped between JavaScript Object and SQL? ▾

When converting hierarchical structures (Arbitrarily nested JS objects and arrays) and tabular or config formats (Relational table schema with batch INSERT tuples), our engine automatically flattens or unflattens dot-separated keys (such as address.city) and preserves numbers, booleans, arrays, and null values.

Is this JavaScript Object to SQL converter free for commercial and production config files? ▾

Yes. The tool is completely free, requires no account or API key, and works offline once loaded. Because execution happens in local memory, it is safe for proprietary JavaScript Object, database exports, and production secrets.

Can I convert SQL back to JavaScript Object? ▾

Yes! Click the "Swap (SQL → JavaScript Object)" button at the top of the workspace or use the reverse converter link at the bottom of this page for bidirectional conversion.
