Frequently Asked Questions

Which SQL dialects are supported?
The tool supports MySQL, PostgreSQL, SQLite, and SQL Server. Each dialect uses proper identifier quoting, string escaping, and data types.
How does type detection work?
The tool scans all values in each column. If all non-null values are integers, it uses INT/INTEGER. If all are decimals, it uses DECIMAL/NUMERIC. ISO date patterns map to TIMESTAMP/DATETIME, booleans to BOOLEAN/BIT, and everything else to VARCHAR(255) or TEXT.
Is my data secure?
Yes! All parsing and SQL generation happens entirely in your browser. Your data is never sent to any server.
What are batch inserts?
Batch inserts group multiple rows into a single INSERT statement (up to the batch size you set). This is more efficient than individual INSERT statements for large datasets.
