How does the tool infer SQL column data types?

The converter scans all data rows in each column. If every non-null value matches integer patterns, it assigns INTEGER. If numbers contain decimal points, it infers NUMERIC/DECIMAL. Dates, timestamps, booleans, and strings are similarly identified automatically.

Which SQL database dialects are supported?

Toolbox supports five major relational database dialects: PostgreSQL, MySQL / MariaDB, SQLite, Microsoft SQL Server (T-SQL), and Oracle Database. Each dialect uses native identifier quoting, boolean representations, and data types.

Is my CSV data uploaded to any remote server?

No. All CSV parsing, type inference, and SQL query generation execute 100% in your browser using client-side JavaScript. Your confidential records, customer emails, and financial data never leave your local machine.

How are NULL and empty CSV values handled?

Empty fields and values matching 'null' (case-insensitive) are converted to native unquoted SQL NULL literals, preventing empty strings from corrupting numeric or boolean database columns.

Can I convert large CSV files with thousands of rows?

Yes. The batching option lets you group thousands of rows into clean multi-row INSERT blocks (e.g. 100 or 500 rows per statement), preventing database packet size limits or stack overflows when running the script.

How to Use CSV to SQL Converter

Paste or Upload CSV

Paste your raw CSV text directly into the editor or upload a .csv or .tsv file from your computer.

Select SQL Dialect & Table Name

Choose your target relational database dialect (PostgreSQL, MySQL, SQLite, MSSQL, or Oracle) and name your destination table.

Configure Schema Options

Toggle CREATE TABLE, DROP TABLE, identifier quoting, auto-increment primary keys, and customize the batch insert size.

Copy or Download SQL Script

Instantly copy the generated SQL statements to your clipboard or download them as a .sql file ready for execution.

Pro Tips

Set batch size to 500 for fast bulk inserts in PostgreSQL or MySQL

Ensure your first row contains unique header column names

Toggle 'Quote Identifiers' off if you prefer unquoted table and column names
