Why use Parsy as your XML Formatter?

Dealing with raw XML, RSS, or Atom feeds in the browser is notoriously difficult. Instead of copying and pasting sensitive data into online formatting tools, Parsy works as a local XML Viewer Chrome Extension that beautifies your data instantly on the page.

Our extension automatically detects XML responses and transforms them into a highly readable, interactive tree view. It natively supports XML attributes, collapses large nodes, and includes a blazing-fast search function (Ctrl+F) to help you find specific keys and values within massive files.

100% Privacy and Security

Unlike web-based formatters, Parsy operates completely offline. Your data never leaves your browser, ensuring maximum security for proprietary API responses and sensitive feeds. Plus, with zero dependencies and a sleek dark mode, it's built explicitly for developer productivity.
