Convert JSON Data to SQL

This tool helps developers quickly seed databases by converting generic JSON arrays into valid SQL INSERT statements. It is particularly useful when migrating data from NoSQL databases (like MongoDB) or APIs into relational databases like MySQL, PostgreSQL, or SQLite.

How it works

Parsing: The tool parses your input text as JSON.
Inference: It looks at the first object in the array to determine column names and data types (Integer, Text, Boolean).
Generation: It constructs standard SQL INSERT INTO statements, escaping single quotes in string values to prevent syntax errors.

Tips

Ensure your JSON is a valid array of objects. Mixing object structures within the same array may result in missing columns if the first object doesn't represent the full schema. For huge datasets, consider chunking your input to avoid browser memory limits.
