Migrating data from spreadsheets to relational databases is a common developer task. Our CSV to SQL converter simplifies this by generating ready-to-run INSERT or UPDATE statements. Whether you're using MySQL, PostgreSQL, or SQL Server, we've got you covered.

What is CSV to SQL Conversion?

CSV to SQL conversion takes tabular data from a CSV file and wraps it in structured Query Language (SQL) syntax. Instead of manually typing commands, our tool generates thousands of lines of SQL code formatted for your specific database engine.

Why Use Our CSV to SQL Converter?

  • Supports multiple SQL dialects (MySQL, Postgres, SQL Server)
  • Automatic data type detection for strings, numbers, and NULLs
  • Generates single or bulk INSERT statements
  • Secure browser-side processing - no data logs
  • Customizable table and column names
  • Proper handling of SQL escaping and quotes

How to Convert CSV to SQL

1

Paste CSV Data

Paste your CSV text. Ensure the first row contains valid column names.

2

Set Table Name

Specify the target database table name (e.g., "users" or "products").

3

Choose Format

Select your database type and whether you want INSERT, UPDATE, or UPSERT.

4

Download Script

Copy the generated SQL or download it as a .sql file.

Key Features

Dialect Switching

Tailors syntax for backticks (MySQL) vs double quotes (PostgreSQL/Oracle).

Bulk Inserts

Combines multiple rows into a single INSERT statement for faster execution.

NULL Handling

Identifies empty CSV cells and correctly converts them to SQL NULL values.

Constraint Support

Can include IF NOT EXISTS or ON DUPLICATE KEY UPDATE clauses.

Type Mapping

Attempts to map CSV data to SQL types like VARCHAR, INT, and DATE.

Best Practices

  • Clean your CSV headers to remove spaces or special characters
  • Validate date formats to ensure they match your SQL column type
  • Use multi-row inserts for large datasets to improve performance
  • Wrap your generated script in a transaction for safety
  • Sanitize values to prevent accidental SQL injection characters

Common Use Cases
