The SQL Formatter takes messy or minified input and turns it into cleanly-indented, readable output — or the reverse, when you need the smallest possible payload. Syntax errors are highlighted so you can fix them on the spot, and the whole process runs locally in your browser. Ideal for debugging API responses, sharing snippets in tickets, or preparing code for a blog post.
Drop your code into the editor — it accepts files of any size that your browser can handle.
Set indent width, comment handling, and other format preferences from the toolbar.
Click the format button to process the code entirely in your browser — nothing is uploaded.
Copy the format-ready code to your clipboard or save it as a file for your build pipeline.
Ugly, minified, or inconsistently indented code is a productivity tax. SQL Formatter normalizes formatting so diffs are meaningful, code reviews stay focused on logic, and beginners aren't intimidated by wall-of-text output. It's the kind of tool you invoke reflexively — copy, paste, tidy, back to work. Toolzer's design philosophy is simple: privacy-first (no tracking, no accounts), performance-first (the page is interactive in under a second on a 3G connection), and honesty-first (no fake ratings, no dark patterns, no upsells). SQL Formatter follows the same rules as every other utility on the site. You can bookmark this page, share the URL with a colleague, or pin it to your browser's toolbar — the experience will be identical every visit, and it will keep working even if you're on airplane Wi-Fi. Real people use this tool for real work — freelancers cleaning up client deliverables, sysadmins triaging tickets, students finishing assignments — and it is tuned for those workflows, not for demo videos.
The SQL Formatter points out syntax errors with a line number and short message, but it does not silently rewrite invalid input — you stay in control of the fix.
Yes. Both directions are supported: pretty-print for reading/debugging, minify for shipping the smallest payload.
No. Formatting only changes whitespace and indentation. The underlying data structure is preserved bit-for-bit.
No. Formatting runs entirely in your browser.
Yes — free, unlimited, no signup.

JSON is the lingua franca of modern APIs, configs and logs — but it is unreadable when minified onto one line.
Base64 encodes binary data as ASCII text so it survives email, JSON, HTTP headers and other text-only chann…
JSON Web Tokens encode user identity and claims into a compact, signed string used by most modern APIs.
Hash functions turn any input into a fixed-length fingerprint.
The JSON Schema Generator produces high-quality output on demand — click generate as many times as you like…
The JSON to TypeScript is a fast, single-purpose tool that focuses on doing one job well.
