How to convert JSON to SQL

  1. Step 1 – Input JSON Array

    • For direct table insertion, provide an array of objects (e.g., [{"id": 1, "name": "Alice"}]).
    • Each object represents a row, keys become column names, and values become cell data.
    • You can also import a JSON file containing your dataset using the Import button.

  2. Step 2 – Configure Database & Table

    • Dialect Selection: Choose your target database (MySQL, PostgreSQL, Oracle, SQL Server, or SQLite) to ensure correct syntax for strings, quotes, and escapes.
    • Table Name: Specify the target table name for the INSERT statements.
    • Create Table: Optionally enable "Include CREATE TABLE" to generate the schema definition automatically based on your JSON data types.

  3. Step 3 – Generate SQL

    • The tool instantly generates formatted INSERT INTO statements.
    • Click "Copy" to use the SQL immediately in your database client (DBeaver, pgAdmin, etc.).
    • Or click "Download" to get a .sql script file ready for meaningful data migration or backup restoration.
Example: JSON to SQL
// Input JSON
[
  { "id": 1, "name": "Alice" },
  { "id": 2, "name": "Bob" }
]

// Output SQL (MySQL)
INSERT INTO data_table (id, name) VALUES (1, 'Alice');
INSERT INTO data_table (id, name) VALUES (2, 'Bob');

Frequently Asked Questions

What JSON structures can be converted to SQL?

Arrays of objects work best as each object becomes a table row. Single objects are converted to single INSERT statements. Nested objects are serialized as JSON strings.

How are JSON data types handled?

Strings are quoted and escaped, numbers remain as-is, booleans become TRUE/FALSE, null becomes NULL, and complex objects/arrays are JSON-encoded as strings.

Can I customize the table structure?

Yes! You can set custom table names, include CREATE TABLE statements with TEXT columns, and control which part of your JSON to convert.

What about table relationships?

If your JSON objects have a '_table' field, that value will be used as the table name for that specific record, allowing multi-table INSERT generation.

Is my data secure?

Yes, all data processing happens entirely in your browser. Your JSON data is never sent to any server, ensuring complete privacy and security.
