Questions
How do I convert a SQL table to JSON Schema?
Paste your CREATE TABLE statement into the input field. The tool parses column names, types, and constraints to produce a JSON Schema with proper type mappings (e.g., VARCHAR to string, INT to integer).
What SQL dialects are supported?
The converter supports standard SQL CREATE TABLE syntax compatible with PostgreSQL, MySQL, SQLite, and SQL Server. Column types like VARCHAR, INT, BOOLEAN, TIMESTAMP, JSON, and UUID are all mapped correctly.
Does the SQL to JSON Schema converter handle NOT NULL constraints?
Yes, columns marked NOT NULL are added to the required array in the JSON Schema. Nullable columns are left optional.
Is the SQL to JSON Schema converter safe for database schemas?
Yes, all parsing happens in your browser. No SQL statements are sent to any server, so your schema definitions remain private.
Can I convert multiple CREATE TABLE statements at once?
Yes, paste multiple CREATE TABLE statements and the tool will generate a separate JSON Schema definition for each table.
