Free No signup Client-side Privacy friendly Updated

How to use

  1. 1 Paste your CSV data.
  2. 2 Enter the target table name and choose the SQL dialect.
  3. 3 Toggle "Include CREATE TABLE" to add a best-guess schema at the top.
  4. 4 Copy or download the generated SQL — one INSERT per row.

Why use this tool

  • Four dialects — MySQL, PostgreSQL, SQLite, SQL Server. Identifiers quoted appropriately for each.
  • String literals use single-quote doubling — portable across all four targets.
  • Cell type inference — empty becomes NULL, numbers stay unquoted, everything else escaped string.
  • Optional CREATE TABLE with best-guess column types (INT / DECIMAL / TEXT).

Frequently asked questions

How are NULLs detected?

Any empty cell becomes the literal NULL (no quotes). To insert an empty string instead, set the cell to a single space or modify the SQL output.

Does it handle Postgres-specific types like JSONB?

No — column inference is limited to INT, DECIMAL, TEXT. Edit the CREATE TABLE manually if you need JSONB, ARRAY, or other extended types.

Will the SQL be properly formatted?

One statement per line. For pretty-printing, run the output through the <a class="text-brand-600 hover:underline" href="/sql-formatter">SQL Formatter</a>.

What is CSV to SQL Converter?

A CSV to SQL Converter is a tool that generates SQL INSERT statements from CSV data, mapping the header row to column names and each row to a set of values. It runs in the browser, supports MySQL, PostgreSQL, SQLite, and SQL Server dialects, and can optionally emit a matching CREATE TABLE statement for the target table.

Features

Four SQL dialects

MySQL (backtick), PostgreSQL/SQLite (double-quote), and SQL Server (bracket) identifier quoting.

Optional CREATE TABLE

Infers column types and emits a matching CREATE TABLE alongside the INSERTs.

100% private

Runs client-side — your data is never uploaded.

Example

Input

name,role
Ada,Engineer   (dialect: MySQL, table: users)

Output

INSERT INTO `users` (`name`, `role`) VALUES ('Ada', 'Engineer');

Common use cases

  1. 1

    Seed a database

    Turn a spreadsheet export into INSERT statements to load into a dev or test database.

  2. 2

    Migrate tabular data

    Convert CSV from one system into SQL for another, in the right dialect.

  3. 3

    Bootstrap a schema

    Generate CREATE TABLE + INSERTs to stand up a table from sample data.

Summary

Zerethon's CSV to SQL converter generates INSERT statements from CSV data in your browser, mapping the header row to column names and each row to a set of values. It supports MySQL, PostgreSQL, SQLite, and SQL Server dialects — quoting identifiers and escaping literals per dialect — and can optionally emit a matching CREATE TABLE. Nothing is uploaded.
