The converter built for real database loads.

SQLified turns large delimited data files — CSV, TSV, pipe- and semicolon-separated — into clean, importable SQL. For any file it produces a CREATE TABLE statement plus batchedINSERT statements, with column types inferred from your data and full control to adjust them. It runs entirely in your browser: your file never leaves your machine.

Why we built it

SQLified started with a recurring, unglamorous problem: loading big data files into a database, month after month. The free online converters are fine for a fifty-row sample, but drop a real export on them — a few hundred thousand rows, or a couple million — and the tab freezes, or the SQL they spit out fails on import because it ignores the database's own limits. We kept hand-fixing those scripts, so we built a tool that does it right the first time.

The result is a converter aimed at the people who move data on a schedule: analysts staging exports, developers seeding databases, and teams migrating between systems. It's fast on large files, correct across four SQL dialects, and it respects the quirks that break naive converters.

What makes it different

• Scale: built and tested on files of 1,000,000+ rows, not toy samples.
• Correct batching: INSERTs are chunked to respect SQL Server's 1,000-row limit and MySQL's max_allowed_packet, so big scripts import cleanly.
• Smart type inference: INTEGER vs BIGINT by range, decimal scale for currency, dates, booleans, and percentages — all editable before export.
• Four dialects: PostgreSQL, MySQL, SQL Server (T-SQL), and SQLite, each with the right types and identifier quoting.
• Private by design: conversion happens locally in your browser; nothing is uploaded, stored, or transmitted.

Who makes SQLified

SQLified is built and maintained by Octet Software, a small independent studio. We build focused, practical tools and stand behind them — if something's broken or missing, a real person reads your email. You can reach us any time on our contact page.
