CSV to SQL INSERT Generator — Free Online
Convert CSV data into ready-to-run SQL INSERT statements for SQL Server, PostgreSQL, MySQL, SQLite, or Oracle. Handles type inference, NULL tokens, quoting, escaping, and datasets up to 50,000+ rows — all in your browser.

What This Tool Does
This generator converts CSV (Comma-Separated Values) data into production-ready SQL INSERT statements. You paste or upload a CSV file, configure your target database dialect and options, and the tool produces a complete SQL script — including optional CREATE TABLE, transaction wrappers, and batched multi-row INSERTs.
It handles the tedious details: escaping single quotes, mapping CSV columns to SQL types, converting null-like tokens (NULL, n/a, none) to SQL NULL, quoting identifiers correctly per dialect, and generating batched statements that won't exceed database limits. For the reverse workflow — exporting SQL query results to CSV — try the JSON to CSV converter after running your query.
Supported SQL Dialects
| Dialect | Identifier Quoting | String Type | Bool Type | Notes |
|---|---|---|---|---|
| SQL Server | [name] | NVARCHAR(n) | BIT | Unicode N'' prefix supported |
| PostgreSQL | "name" | TEXT | BOOLEAN | TRUE/FALSE literals |
| MySQL | `name` | TEXT | TINYINT(1) | Backtick quoting |
| SQLite | "name" | TEXT | INTEGER | Dates stored as ISO text |
| Oracle | "name" | VARCHAR2(n) | NUMBER(1) | INSERT ALL syntax |
How to Use the CSV to SQL INSERT Generator
- Drop a CSV file or paste CSV text into the input area
- The tool auto-detects the delimiter, headers, and column types
- Review the column mapping table — rename columns, change types, or exclude columns
- Select your target database dialect
- Set the table name, schema, and batch size
- Click Generate SQL
- Copy the SQL output or download as a
.sqlfile
Type Inference
The tool samples up to 500 rows (configurable) and infers each column's type: int, float, bool, date (YYYY-MM-DD), datetime (ISO format), or string. Each generic type maps to the correct dialect-specific type — for example, int becomes INT in SQL Server but INTEGER in PostgreSQL. You can override any column to a different type or switch all columns to text for a quick import.
NULL and Empty String Handling
Values matching configurable null-like tokens (NULL, n/a, na, none — case-insensitive) are output as SQL NULL. Empty strings can be treated as either literal empty strings ('') or as NULL via a global toggle. Whitespace is trimmed before the null check if the trim option is enabled.

Privacy & Security
All CSV parsing and SQL generation runs in your browser using JavaScript and a Web Worker. Your data — whether it contains customer records, financial data, or proprietary business information — is never transmitted to any server. You can verify this by watching the Network panel in browser developer tools while using the converter.
