The Complete Guide to Converting CSV to SQL

Why CSV to SQL?

CSV is ubiquitous — it's how databases export data, how spreadsheets share data, and how almost every data tool accepts data. SQL is how you query it. Converting between them is one of the most common operations in data engineering.

The naive approach

Most people do this manually: open the CSV in Excel, note the columns, write a `CREATE TABLE` statement, then write `INSERT` statements by hand. This works for 5 rows. It breaks for 50,000.

What DataForge AI does differently

**Automatic type inference** — We analyse every value in each column and infer the appropriate SQL type (`BIGINT`, `DECIMAL`, `VARCHAR`, `DATETIME`, etc.)

2. **Dialect support** — Generate MySQL, PostgreSQL, SQLite, SQL Server, or Oracle DDL in one click

3. **AI assistance** — For ambiguous columns (mixed types, inconsistent formats), the AI resolves them sensibly
