Your history is safe, with full undo support that lets you revert any change with a single click.

Format and Beautify SQL Queries

Transform messy or compressed SQL into a clean, professional layout with our built-in formatter. To improve readability, major clauses such as SELECT, FROM, and WHERE are automatically moved to new lines, while logical conditions like AND or OR are indented for better visual hierarchy. You can standardize your code instantly with automatic keyword capitalization. Subqueries and complex column lists also become much easier to navigate through intelligent nesting and indentation, producing clean, production-ready code that is ready for peer review.

Validate SQL Syntax Before Running

Avoid the frustration of failed executions by identifying syntax issues before they hit your database. This validator thoroughly scans your input for missing semicolons, unmatched parentheses, unclosed strings, and other common mistakes. Visual feedback appears immediately in the validation panel, with clear color coding for errors and warnings to help you fix problems fast.

Minify SQL and Convert INSERT Statements to CSV

Optimized, one-line queries are perfect for embedding inside your application code or configuration files. The minification tool strips away all comments and unnecessary whitespace to create a compact footprint without changing your underlying logic. This results in a streamlined query that maintains its full functionality while removing any extra bloat.

Convert INSERT INTO Statements to CSV Format

Exporting data from INSERT statements into spreadsheets is effortless with our integrated converter. It automatically maps your SQL columns to CSV headers and converts each value row into a data entry. You can process multiple statements or multi-row inserts at once, producing a unified CSV output that is ready for use in any spreadsheet application.

Undo, Redo, and Keyboard Shortcuts

Never worry about making a mistake, as your entire edit history is tracked for instant recovery. Standard keyboard shortcuts like Ctrl+Z and Ctrl+Y are fully supported, alongside dedicated toolbar buttons for undo and redo. You can further enhance your coding experience with searchable text, adjustable font sizes, and smart tab indentation.
