About this tool
SQL Insert Generator converts CSV rows into executable INSERT statements for faster database import and test-data setup. It supports header-based column mapping, custom delimiters, identifier quoting, batch chunking, empty-to-NULL conversion, and basic numeric/boolean type detection. This helps backend engineers and analysts prepare seed data, migration scripts, and QA fixtures without writing repetitive SQL manually. Output is generated locally in your browser, making it safe for internal datasets and pre-production workflows.
Direct Answers
Should empty CSV cells become NULL automatically?
Only when that matches your import intent. Empty strings and NULL are not interchangeable in every schema.
