CSV to SQL Converter

What Can the CSV to SQL Converter Do?

The CSV to SQL Converter is a pure frontend online tool for converting CSV data into SQL statements. It supports generating CREATE TABLE statements (with automatic column type inference) and INSERT statements, compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Standard SQL dialects. It supports multiple CSV separators, single/batch INSERT modes, and file drag-and-drop. All conversion is done locally in your browser — data is never uploaded to any server.

Core Features

• CREATE TABLE Generation: Automatically analyzes CSV data to infer column types (INT/BIGINT/FLOAT/DATE/VARCHAR, etc.) and generates CREATE TABLE statements
• INSERT Statement Generation: Supports single-row and batch INSERT modes with proper special character escaping
• Multi-DB Dialects: Compatible with MySQL, PostgreSQL, SQLite, SQL Server, and Standard SQL syntax differences
• Multi-Separator Support: Supports comma, tab, semicolon, and pipe separators
• File Drag & Drop: Drag CSV files onto the input area to automatically load content

How to Use

Step 1: Set table name, SQL dialect, separator, and INSERT mode.

Step 2: Paste CSV data in the text area (first row as headers), or drag a CSV file.

Step 3: Click "Convert to SQL" or use Ctrl+Enter to view generated SQL statements.

Step 4: Click "Copy SQL" to copy to clipboard, or "Download SQL" to save as a file.

Extended Knowledge

CSV (Comma-Separated Values) is the most universal data exchange format, with RFC 4180 defining its standard specification. SQL INSERT statements come in two forms: INSERT INTO table VALUES (...) omitting column names (depends on column order) and INSERT INTO table (col1, col2) VALUES (...) specifying column names (safer). Batch INSERT combines multiple rows into one statement, like INSERT INTO table VALUES (...), (...), (...), reducing network round-trips and log writes, performing several times better than single-row INSERT. Different databases have slight syntax variations for batch INSERT.
