JSON to SQL
Generate CREATE TABLE and INSERT statements from a JSON array.
What is JSON → SQL?
The JSON to SQL tool takes an array of objects and generates SQL CREATE TABLE + INSERT statements suitable for database seeding, test fixtures, or data migration.
How it works
We parse the JSON and infer SQL column types from the first row (INTEGER, REAL, TEXT, DATE). Then generate CREATE TABLE with all columns and INSERT statements for every row.
- Paste JSON array. Drop or paste a JSON array of objects.
- Configure options. Set the table name and optional DROP TABLE prefix.
- Copy or download. Copy the SQL or download as .sql.
Examples
User data
[{"name":"Alice","age":30}] generates CREATE TABLE data ("name" TEXT, "age" INTEGER); INSERT INTO data ("name", "age") VALUES ('Alice', 30);
Common mistakes
Mixed types
Column types are inferred from the first row. If a later row has a different type, the INSERT will still use the inferred type.
Alternatives
JSON to CSV
Generate CSV instead of SQL for spreadsheet import.
