Frequently Asked Questions
Is my data sent to a server?
No. All conversion happens locally in your browser using JavaScript. Your CSV data never leaves your device, ensuring complete privacy.
Can I convert large CSV files?
Yes, but for very large files (10MB+), you may experience slower performance. Consider splitting large files into smaller batches.
Does this work with all SQL databases?
Yes. The generated SQL uses standard INSERT syntax compatible with MySQL, PostgreSQL, SQL Server, SQLite, and other SQL databases.
How do I handle quoted values?
The tool handles quoted values automatically. If your data contains commas within a field, enclose that field in double quotes.
