Frequently asked questions (XLSX to SQL)

Which SQL databases are supported?

The generated INSERT statements follow standard SQL syntax and work with MySQL, PostgreSQL, SQL Server, SQLite, and most other relational databases. You may need to adjust table names or quoting depending on your database.

Does it handle large Excel files (e.g., 100,000 rows)?

Yes – performance depends on your device’s memory and browser engine. Most standard Excel files (up to 50MB) convert instantly. Very large files may take longer, but all processing remains local.

Can I edit the Excel data before converting to SQL?

Absolutely. The preview table is fully editable. You can change cell values, insert or delete rows, and even rename column headers – then generate SQL from the modified data. All live in your browser.

How are special characters like quotes and apostrophes handled?

All values are safely escaped for SQL. Single quotes are doubled (''), backslashes are escaped, and other special characters are handled correctly to prevent syntax errors.

Is my Excel file uploaded to a server?

No. The tool runs entirely in your browser using the SheetJS library. Your file never leaves your computer – even works offline after first load.

Is this XLSX to SQL converter really free?

Yes, completely free. No hidden fees, no premium tiers, no watermarks. DataFrog believes developer tools should be accessible to everyone.
