📋 When to Use the SQL Formatter

The SQL Formatter is ideal when you need to convert between formats or units quickly — whether you're reformatting data for a different tool, preparing content for a client, or just trying to make sense of incompatible file types. Use it when working remotely without access to desktop software, when sharing screens in a meeting and need a fast conversion, or when you want to avoid uploading sensitive files to unknown servers. Everything processes in your browser for maximum privacy.

⚙️ How the SQL Formatter Works

The SQL Formatter processes your input using conversion algorithms that run entirely in your browser. When you paste or upload content and select the output format, JavaScript parses the input, transforms it using format-specific logic (encoding, decoding, parsing, serializing), and produces the converted output. For file conversions, all processing uses browser-native APIs and JavaScript libraries loaded from CDN — your files are never uploaded to any server. The entire pipeline from input to output stays on your device.

How to Use the SQL Formatter

Paste your SQL — Drop any SQL query into the input area. It works with messy, minified, or oddly-formatted SQL.
Choose your dialect — Select Standard SQL, MySQL, PostgreSQL, or SQLite. Each has slightly different formatting rules.
Click Format — Your SQL is instantly beautified with proper indentation, line breaks, and keyword capitalization.
Or click Minify — Compress your SQL to a single line for embedding in code or reducing file size.

Frequently Asked Questions

Does it validate my SQL?

The formatter focuses on formatting, not validation. It will format syntactically correct SQL. For validation, run your query against your actual database.

Which SQL dialects are supported?

Standard SQL, MySQL, PostgreSQL, and SQLite are supported. Each uses slightly different keyword casing and formatting conventions.

Is my data sent to a server?

No. All formatting happens entirely in your browser using the sql-formatter library. Your queries never leave your device.

Can I format large queries?

Yes! The formatter handles queries of any length. Performance depends on your device, but most queries format in under a second.
