Readable, Correct SQL

SQL copied from logs or an ORM usually arrives as one long line. The SQL Query Formatter puts each clause on its own line so you can review it, the SQL Query Validator catches unbalanced quotes and parentheses, and the SQL Minifier turns a query back into a single line for code or config.

Generate Statements Instead of Typing Them

Build statements from a form with the INSERT, UPDATE and DELETE generators, assemble conditions with the SQL WHERE Builder and SQL JOIN Builder, and design tables visually with the SQL Table Generator or Database Schema Designer.

Moving Data In and Out

Import a spreadsheet with the CSV to SQL Converter, or JSON with the JSON to SQL Converter.
Pick the right column type with the MySQL, PostgreSQL and SQL Server data type references.
Working outside SQL? Try the MongoDB Query Formatter and Redis Command Builder.

Our guide on formatting SQL covers the style rules behind the formatter.
