All JSON → MySQL conversion happens locally in your browser. No data is uploaded to our servers, ensuring full privacy.
The tool looks at all values for each key across rows and picks suitable types like INT, DOUBLE, TINYINT(1) for booleans, VARCHAR(255), DATE/DATETIME, JSON, or TEXT when types are mixed.
Frequently Asked Questions
What JSON structure works best for this tool?
Use either a single JSON object (for one row) or an array of objects (for multiple rows). Each top-level key becomes a column. Nested objects and arrays are stored as JSON strings in JSON/TEXT columns.
How are MySQL column types inferred?
The tool looks at all values for each key across rows and picks suitable types like INT, DOUBLE, TINYINT(1) for booleans, VARCHAR(255), DATE/DATETIME, JSON, or TEXT when types are mixed.
Is my data safe when generating SQL?
Yes. Everything runs in your browser and never leaves your device. Strings are also escaped in the generated SQL to avoid syntax errors.
Can I convert big JSON datasets?
This depends on your browser memory, but typical export-sized JSON (thousands of rows) is usually fine. For very large migrations, consider chunking data or using a backend script.
