XML Viewer & Formatter

Auto-detect XML, WSDL & SOAP in browser. Format, minify, tree view, XPath and JSON conversion. Supports RSS, Atom, SVG and XSD.

XML Viewer & Formatter — Format, explore and convert any XML directly in your browser. XML Viewer & Formatter turns any raw XML document into a clean, navigable, editable view — automatically. When you open an XML document in your browser, the extension takes over with formatting, search, a tree explorer, an interactive chart and one-click XML-to-JSON conversion. No setup, no account, no servers. If you have ever opened a SOAP response or a WSDL file and stared at a single unformatted line of text, this is the tool that fixes it. It also handles XSD schemas, RSS and Atom feeds, and SVG and SAML documents. ═══════════════════════════════ WHAT YOU CAN DO ═══════════════════════════════ — Format & edit — - Pretty-print (beautify) XML with one click or Ctrl+Enter. - Minify XML to a single line with Ctrl+Shift+M. - Edit XML directly in a syntax-highlighted editor with code folding, line numbers and live cursor position. — Search & navigate — - Find text across the whole document (next / previous). - Find & Replace — replace all occurrences at once. - Run XPath queries with namespace support (up to 200 results). - Jump to any line number. — Load XML from anywhere — - Auto-detected when you open an XML document in the browser. - Load by URL (with CORS fallback). - Upload a local XML file. - Paste XML directly. — Multiple views — - Editor — full editable source with syntax highlighting. - Tree — collapsible hierarchy with expand / collapse all. - Chart — interactive D3.js diagram (zoom, pan, click). - JSON — convert XML to JSON (Raw or API Style mode). — Export — - Copy XML or JSON to clipboard. - Download the formatted document or its JSON conversion. — Configurable — - Choose which document types trigger auto-detection. - Block specific websites from triggering the viewer. - Dark and Light themes. ═══════════════════════════════ PRIVACY — NO TRACKING. NO SERVER. NO ADS. ═══════════════════════════════ All processing happens locally in your browser. The extension does not collect, transmit, or store any data on remote servers. Detection is fully local (URL pattern, Content-Type, or the first characters of the document). You can disable any detection strategy and add sites to a block list in Settings.

The extension brings that same formatting to every XML document you open, automatically and offline, with no copy-paste. More tools at wsdlsoap.com
