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
Paste CSV Data
Paste your CSV text. Ensure the first row contains valid column names.
Set Table Name
Specify the target database table name (e.g., "users" or "products").
Choose Format
Select your database type and whether you want INSERT, UPDATE, or UPSERT.
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
Database Seeding
Quickly populate local development databases with sample CSV data.
Data Migration
Move legacy spreadsheet data into modern SQL-based applications.
Bulk Updates
Generate UPDATE statements to refresh product prices or user statuses.
SQL Backups
Convert exported data tables back into executable SQL scripts.
