Frequently Asked Questions

What SQL dialects are supported?

The tool supports MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), and Oracle. Each dialect uses appropriate data types and syntax for CREATE TABLE and INSERT statements.

How does automatic data type detection work?

The tool analyzes the values in each column to determine the best SQL data type. Integers become INT, decimals become DECIMAL, boolean-like values (true/false/yes/no) become BOOLEAN, and everything else becomes VARCHAR. You can disable this and use TEXT for all columns if preferred.

Is there a limit on file size?

There is no strict file size limit — the tool processes data entirely in your browser. Very large files (tens of MB) may take a moment to process depending on your device's performance. For extremely large datasets, consider splitting into smaller files.

Is my data secure?

Absolutely. All conversion happens entirely in your browser using JavaScript. No CSV data or generated SQL is ever sent to any server, ensuring complete privacy and security for sensitive information.

Can I generate CREATE TABLE statements?

Yes. Enable the "Generate CREATE TABLE statement" option, and the tool will produce a CREATE TABLE statement with appropriate column names and detected data types, followed by the INSERT statements.
