About CodingFormatter | Privacy-First Developer Tools
CodingFormatter is a suite of free online developer tools spanning formatters, validators, converters, encoders & utilities, and AI/LLM helpers. It is built for people who paste sensitive data into tools every day and deserve a privacy-first default.
Every tool runs entirely in your browser with JavaScript. There is no application backend that stores pastes, no “upload to process” step, and no account wall. That constraint—static hosting—is also the product promise on every page: your data never leaves your browser.
The catalog covers day-to-day engineering workflows: pretty-print JSON, XML, HTML, and SQL; validate YAML, JavaScript, HTML, regex, paths, and links; convert CSV, YAML, XML, colors, images, IDN domains, and Unix timestamps; encode Base64 and inspect JWTs; sanitize HAR files; and support LLM work with token counts, context windows, prompt lint/diff/minify, schema validation, and embedding similarity.
Each tool page targets a clear job-to-be-done search query, with Monaco-powered editors where they help, consistent UX across categories, and honest client-side processing. We keep expanding the suite without changing the privacy model.
