JSON to SQL
JSON to SQL
Generate SQL CREATE TABLE and INSERT statements from a JSON array of objects.
How to Use JSON to SQL
- 1.Paste a JSON array Paste a JSON array of objects - each object becomes a table row.
- 2.Set table name Enter a name for the SQL table (defaults to 'items').
- 3.Choose SQL dialect Select MySQL, PostgreSQL, or SQLite for dialect-specific syntax.
- 4.Copy the SQL Copy the CREATE TABLE and INSERT statements to run in your database.
JSON to SQL & JSON Developer Standards
JSON is the standard format for web APIs and modern applications. Using the JSON to SQL helps you check syntax, catch formatting errors, and keep your data clean and readable.
Zero-Server Security
All data entered into JSON to SQL runs directly inside your browser sandbox. Nothing is ever sent across the network or saved on remote servers.
Clean & CI/CD Ready
Well-formatted JSON prevents runtime syntax bugs, makes code reviews easier, and ensures smooth API data exchange.
JSON to SQL Frequently Asked Questions
What SQL dialects are supported?
The generator outputs standard SQL compatible with MySQL, PostgreSQL, and SQLite. Dialect-specific options include backtick vs double-quote identifier quoting, and data type choices (e.g. TEXT vs VARCHAR).
How are JSON types mapped to SQL types?
JSON strings become VARCHAR or TEXT, numbers become INT or NUMERIC (depending on whether they are integers or floats), booleans become BOOLEAN or TINYINT(1), and null is stored as NULL. Nested objects are serialised as JSON text.
What about nested objects in the JSON?
Nested objects and arrays cannot be stored directly in a flat relational table. The generator serialises them as JSON text in a TEXT column. For a normalised schema, you would need to manually split nested objects into separate tables.
Can I import the SQL directly into my database?
Yes. The output is standard SQL that can be executed in any SQL client. For large datasets, consider chunking the INSERT statements or using a bulk import tool.
Can this tool handle large, complex JSON payloads?
Yes. Because the tool operates directly inside modern V8 JavaScript execution engines, it easily processes complex multi-megabyte payloads containing thousands of nested keys with negligible latency.
Are my proprietary payloads or secrets stored or cached?
No. BeYourTools implements zero tracking, zero telemetries, and zero database persistence. Everything stays strictly inside your browser memory and disappears the moment your tab is closed.
