Why Convert CSV to SQL?

In data migration, database initialization, and test data generation scenarios, you often need to import CSV data into a database. Manually writing INSERT statements is time-consuming and error-prone. This tool generates them instantly with automatic column type inference.

Supported Delimiters

Besides standard comma separation, the tool supports tab (TSV), semicolon, and pipe delimiters. Fields containing commas, line breaks, or quotes must be wrapped in double quotes — the tool handles RFC 4180 standard format automatically.

Automatic Type Inference

The tool automatically analyzes each column's data and infers types as INTEGER, BIGINT, NUMERIC, DATE, TIMESTAMP, or TEXT. You can also uncheck CREATE TABLE to generate only INSERT statements.

❓ Frequently Asked Questions (FAQ)

Is the CSV to SQL tool secure?

Absolutely secure. This tool runs entirely in your browser locally. Your CSV data is never uploaded to any server. All conversion operations are performed on your device. The tool works even without an internet connection.

Which databases are compatible with the generated SQL?

The generated SQL INSERT statements are compatible with MySQL, PostgreSQL, SQLite, MariaDB, SQL Server, and other mainstream relational databases. String fields are automatically wrapped in single quotes, numeric fields are kept as-is, and NULL values are handled correctly.

Does CSV to SQL support large files?

Running in the browser, processing capability depends on your device performance. For CSV files exceeding 100,000 rows, batch conversion is recommended. Browser memory limits are typically 1-4GB, sufficient for most daily use cases.

What CSV format requirements does the tool have?

Supports standard CSV format: comma-separated fields with the first row as column names. Fields containing commas, line breaks, or quotes must be wrapped in double quotes. Also supports tab (TSV), semicolon, and pipe delimiters.
