Advanced Tool Features

Unlike standard text formatters, our tool is engineered specifically for advanced database workflows:

1. Smart Syntax Highlighting: Mimics modern dark-themed IDEs (like VS Code or DataGrip) by color-coding keywords, strings, numeric values, functions, and comments.

2. Flexible Indentation: Choose between 2 spaces, 4 spaces, 8 spaces, or native Tabs to match your project’s official style guide.

3. Keyword Case Normalization: Automatically convert messy inputs into standardized UPPERCASE or lowercase SQL statements.

4. Professional Comma Placement: Supports traditional Trailing commas or advanced database Leading commas (placing commas at the front of a newline) for easier query editing.

5. SQL Minifier (Compression): Strips away line breaks, comments, and extra spaces to compact your query into a single line—ideal for embedding SQL in backend code strings (Node.js, Java, Python, PHP).

6. Local Browser History: Automatically saves your last 10 formatted queries to your browser’s localStorage so you never lose your progress, even if you accidentally refresh the page.

7. Native File Integration: Directly import .sql or .txt files from your local storage and download your beautified code with one click.

Supported SQL Dialects

Our formatter utilizes an adaptive parsing algorithm compatible with standard ANSI SQL and all major relational database management systems (RDBMS):
