SQL to JSON Converter

SQL to JSON converts SQL statements into structured JSON objects. INSERT INTO statements become arrays of row objects with typed values (numbers, booleans, null preserved). CREATE TABLE becomes a schema definition with column names, types, and constraints. SELECT queries become query descriptor objects with columns, table, WHERE, ORDER BY, and LIMIT. Useful for migrating data from SQL databases to JSON APIs and NoSQL stores.

Convert SQL statements to JSON. INSERT INTO statements become arrays of typed row objects. CREATE TABLE becomes a schema definition with columns and constraints. SELECT queries become query descriptor objects. Auto-detects types (numbers, booleans, null). Pretty print or compact output.

How to Use

  1. 1

    Paste your SQL statement

    Paste an INSERT INTO, CREATE TABLE, or SELECT statement. Or click a preset to load sample SQL.

  2. 2

    Configure output format

    Toggle Pretty Print on for readable, indented JSON or off for compact single-line output.

  3. 3

    Click Convert to JSON

    The SQL is parsed and converted to structured JSON. INSERT rows become object arrays, CREATE TABLE becomes a schema, SELECT becomes a query descriptor.

  4. 4

    Copy the result

    Click Copy to copy the JSON output. Use it in your API, config file, or data migration pipeline.

Frequently Asked Questions

What SQL statements can be converted to JSON?
This tool converts three types of SQL statements: INSERT INTO (becomes an array of row objects), CREATE TABLE (becomes a schema definition with column names, types, and constraints), and SELECT (becomes a query descriptor with columns, table, WHERE, ORDER BY, and LIMIT). Each statement type produces a different JSON structure optimized for its use case.
How are SQL data types mapped to JSON?
SQL types are automatically mapped: INTEGER/DECIMAL numbers become JSON numbers, TRUE/FALSE become JSON booleans, NULL becomes JSON null, and string values (in single or double quotes) become JSON strings. Date strings remain as strings in ISO format. This preserves type information when migrating from SQL to JSON-based systems.
Can I convert INSERT statements with multiple rows?
Yes. Multi-row INSERT statements like INSERT INTO table (a, b) VALUES (1, 2), (3, 4), (5, 6) are fully supported. Each VALUES group becomes a separate JSON object in the output array. Column names from the INSERT become object keys. This is useful for bulk data export from SQL to JSON.
What is the difference between SQL to JSON and CSV to JSON?
SQL to JSON preserves the SQL structure (table name, column types, constraints) and handles SQL-specific syntax (quoted strings, NULL, booleans). CSV to JSON only converts tabular data without type information — everything is a string unless you add type inference. SQL to JSON is better when you need to preserve schema information or convert INSERT statements.
How do I convert JSON back to SQL?
Use a JSON to SQL or CSV to SQL converter. The JSON array of objects can be converted back to INSERT statements by using column names as keys and values as SQL values. For schema conversion, map JSON types back to SQL column types. This tool's companion CSV to SQL tool handles the reverse direction for tabular data.
Why convert SQL to JSON?
Common reasons: migrating data from relational databases to NoSQL stores (MongoDB, Firebase), creating API mock data from existing database records, documenting table schemas as JSON for API documentation, converting SQL dumps to JSON for data analysis tools, and building seed data files for testing environments.
