JSON to SQL Converter
Convert a JSON array into CREATE TABLE and INSERT statements instantly.
All conversions happen in your browser. No data is sent to our servers - see why that matters. Share links encode your input in the URL itself; nothing is stored on a server. Press Cmd/Ctrl + Enter to convert.
How to Convert JSON to SQL
Paste a JSON array of objects into the input panel. The tool infers a column for every key, detects INTEGER, REAL, BOOLEAN, and TEXT types from the values, and generates a CREATE TABLE statement plus INSERT statements for every row.
Why Convert JSON to SQL?
APIs return JSON but analysis often happens in a database. Converting JSON directly to INSERT statements skips the CSV import dance and gets API data into PostgreSQL, MySQL, or SQLite in seconds.
Common Use Cases
Developers convert JSON to SQL when seeding development databases from API fixtures, importing webhook payloads for analysis, migrating data from NoSQL exports, and building test datasets.
Frequently Asked Questions
What SQL statements are generated?
A CREATE TABLE statement with column types inferred from your data (INTEGER, REAL, BOOLEAN, or TEXT), followed by one INSERT statement per array item.
How are values escaped?
String values are single-quoted with embedded quotes doubled ('') per the SQL standard, null/undefined become NULL, and booleans become TRUE/FALSE.
Which databases does the output work with?
The generated SQL uses standard syntax compatible with PostgreSQL, MySQL, SQLite, and most other relational databases. You may want to adjust types (e.g., VARCHAR lengths) for production schemas.
How do I change the table name?
The statements use my_table by default - a quick find-and-replace on the output gives you any table name you need.
