Description
Open any .xml page as a collapsible tree. Search tags, attributes and text, handle big files, view full screen. Free, offline. XML Viewer opens any .xml page as a readable, collapsible tree — automatically, with nothing to select and nothing to paste. Open an .xml URL or a local .xml file and this XML viewer takes over the page: tags, attributes and text are colour-coded, every node folds and unfolds, and the whole window is used instead of a small box. WHAT THIS XML VIEWER DOES • Automatic. Any address ending in .xml, .rss or .atom is rendered as a tree the moment it opens. No "select the XML first", no extra click. • One click for the rest. XML that comes from an address without an .xml ending — an API response, a feed — opens in the viewer from the toolbar button. The extension asks for access to that one tab, at that moment, and nothing else. • Built for big files. Rows are rendered only for the part of the tree you are actually looking at, so a large XML document scrolls smoothly instead of freezing the tab. • Search that helps. Type once and the XML viewer highlights every match in tag names, attribute names, attribute values and text, with match counter and next / previous buttons. • Fold and unfold. Collapse a noisy branch, expand everything at once, or open just the part you need. • Full screen. One button gives the XML tree the entire screen — useful for long documents on a laptop. • Paste mode. No .xml URL at hand? Paste XML into the popup and the same XML viewer opens it in a tab. • Dark mode. Follows your system theme. PRIVACY This XML viewer works entirely inside your browser. Your documents are never uploaded, never stored on disk and never sent to any server — there is no server. No account, no sign-up, no tracking. WHO IT IS FOR Developers reading API responses and SOAP payloads, QA engineers checking test fixtures, SEO specialists opening sitemap.xml and RSS feeds, integrators looking at exports and configuration files — anyone who opens XML in a browser and wants a tree instead of a wall of text. HOW TO USE 1. Open any .xml link, or drag a local .xml file into the browser. 2. The XML viewer renders it as a tree. 3. If the address does not end in .xml, open the toolbar popup and press "Open this page in the viewer". 4. Use search, fold, unfold and full screen to find what you need. For local files, allow "Allow access to file URLs" on the extension page — Chrome requires this for every extension that reads file:// pages. Free, works offline, no registration.
