Why Use This CSV to SQL Converter?

Multi-Dialect SQL Generation: Generates accurate DDL and DML for MySQL / MariaDB, PostgreSQL, SQLite, Microsoft SQL Server (T-SQL), and ANSI SQL.
Automatic Schema & Type Inference: Analyzes tabular rows to detect integers, decimals, booleans, dates, timestamps, and variable-length strings.
Multi-Row Batch INSERTs: Chunk high-volume records into configurable batch INSERT statements (25, 50, 100, 500 rows) for high-throughput database seeding.
Robust RFC 4180 Parsing: Handles escaped quotes (""), commas within quotes, multiline text inside fields, and automatic delimiter detection (comma, tab, semicolon, pipe).
Customizable DDL Controls: Optional CREATE TABLE, DROP TABLE IF EXISTS, auto-incrementing ID primary key, and NULL value normalization.
100% In-Browser Privacy: All CSV parsing and SQL synthesis execute strictly in your local browser memory. Zero files or data are uploaded.

How to Use CSV to SQL Converter

1

Paste CSV or Upload File

Drop a .csv or .tsv file into the dropzone or paste raw tabular text into the input editor.

Configure Dialect & Table Settings

Choose your target SQL dialect (MySQL, PostgreSQL, SQLite, MS SQL Server), set the table name, and toggle DDL or batch size options.

3

Copy or Download SQL

Review the syntax-highlighted SQL statements, check the inferred schema inspector, and copy to clipboard or download as a .sql file.

Frequently Asked Questions

Which SQL database dialects are supported?
This converter supports MySQL/MariaDB, PostgreSQL, SQLite, Microsoft SQL Server (T-SQL), and standard ANSI SQL, including dialect-specific identifier quoting and data types.
Is my CSV spreadsheet uploaded to an external server?
No. The entire conversion process executes 100% locally in your web browser. No files, records, or table schemas are transmitted across the network.
Does this tool support TSV (Tab-Separated) files?
Yes. The smart delimiter detector automatically identifies tabs, commas, semicolons, and pipe symbols, or you can select your delimiter manually.
How are NULL and empty values handled?
Empty cells and explicit 'NULL' strings are converted to unquoted SQL NULL values by default, preventing unintended blank string insertions.
Can I generate batch INSERT statements for large spreadsheets?
Yes! You can enable batch INSERT mode and select 25, 50, 100, or 500 rows per statement, reducing database network round-trips and transaction overhead.
