Developer Formatters: JSON, XML, HTML, CSS & More

A quick guide to NxtTls formatters — when to use each tool, client-side privacy, and keyboard shortcuts.

NxtTls bundles nine client-side formatters in one hub — JSON, XML, HTML, CSS, SQL, Base64, URL, JSON→CSV, and JSON→XML. Everything runs locally in your browser.

Which formatter to use

JSON/XML/HTML/CSS/SQL formatters help with readability and debugging. Base64 and URL tools handle encoding for APIs and query strings. JSON→CSV and JSON→XML help when integrating with spreadsheets or legacy systems.

Why client-side matters

Sensitive config, API responses, and proprietary code stay on your machine. No account required, no watermarks, no upload logs for formatter tools.
