Collapsible Tree
Navigate complex XML structures by expanding and collapsing individual nodes.
Validation

100% Private
Your XML never leaves your device. All parsing and rendering is done client-side.
One-Click Copy
Copy the formatted XML straight to your clipboard for immediate use.
Mobile Friendly
Works on phones, tablets, and desktops with a fully responsive layout.
🧮 How It Works
DOMParser API with the MIME type application/xml.Step 2 — Validate: If parsing fails, the DOM contains a
parsererror element — the tool surfaces this as a human-readable error message.Step 3 — Serialize: The parsed DOM is walked recursively. Each node type (element, text, comment, processing instruction) is rendered with syntax-specific CSS colour classes.
Step 4 — Tree: A second recursive pass builds interactive
<details>-style tree nodes with toggle state managed by JavaScript event delegation.Uses zero external libraries. The entire pipeline runs on native browser APIs for maximum speed and privacy.
📌 Practical Examples
🇮🇳 Example 1 — GST E-Invoice XML (India)
Businesses in India generating GST e-invoices receive large XML payloads from the IRP portal. Paste that XML here to instantly verify buyer details, invoice amounts, and IRN numbers without opening complex software.
🇮🇳 Example 2 — WordPress Sitemap Inspection
An SEO manager in Bengaluru copies the content of their sitemap.xml and pastes it into the viewer to verify that all product pages and blog posts are correctly indexed with the right priority and last-modified dates.
🇺🇸 Example 3 — SOAP API Response Debugging
A developer in the US receives a complex SOAP envelope from a legacy payment gateway. Using the tree view, they expand the nested Body > Fault > detail nodes to identify the exact error code in seconds.
🌍 Example 4 — RSS / Atom Feed Review
A content team pastes their blog's RSS feed XML to audit all <item> entries, checking that titles, links, and publication dates are correct before distributing the feed to podcast or news aggregators.
❓ What is an XML Viewer?
XML (eXtensible Markup Language) is a structured data format used in APIs, configuration files, sitemaps, invoices, and much more. Raw XML is notoriously difficult to read — it has no visual hierarchy and all elements are crammed into unreadable walls of text.
An XML Viewer solves this by formatting the raw XML with proper indentation, colour-coding each component type, and presenting the document as an interactive tree. This makes it easy to understand the document's structure, locate specific values, and spot errors without any software installation.
It is an essential tool for developers, SEO professionals, data analysts, and anyone who works with APIs or data exchange formats regularly.
