XML (eXtensible Markup Language) is a markup language designed to store and transport data. It uses custom, self-descriptive tags to create a hierarchical data structure.

XML Viewer - View XML in a Collapsible Tree

Q: Why use a tree view for XML?

A tree view is the most intuitive way to visualize the natural hierarchical structure of an XML document. It helps you easily navigate parent-child relationships and understand complex, nested data.

Q: Can this tool handle very large XML files?

The tool runs in your browser, so its performance depends on your computer's memory. It's best for inspecting reasonably sized XML files, as very large files may cause the browser to become slow.

Q: What happens if my XML is invalid?

If your input code is not well-formed XML, the tool will display an error message and will not render the tree. This helps you quickly identify syntax errors in your file.

About the XML Viewer

Our XML Viewer is an online tool designed to help you easily read and understand the structure of any XML file. XML (eXtensible Markup Language) is great for storing and transporting data, but complex files can be hard to read. This tool parses your XML code and displays it in a clean, interactive, and collapsible tree view.

You can paste your XML code or upload a file, and the tool will instantly render a hierarchical tree. This allows you to navigate through the nodes, see the relationships between elements, and inspect attributes and text values clearly. The entire process runs in your browser, so your data is always private.

How to Use the XML Viewer

Enter your XML data into the input editor, or drag and drop an XML file.
The interactive tree view will appear below, updating automatically as you type.
Click the small triangles to expand or collapse parent nodes to explore the XML structure.
The tree displays every element, attribute, and text value, giving you a complete view of your data.
Use the buttons to copy your original XML code or download it as a file.

Frequently Asked Questions

What is XML?

XML (eXtensible Markup Language) is a markup language designed to store and transport data. Unlike HTML, XML tags are not predefined, allowing you to create your own descriptive tags to structure your data. It is a widely used standard for data exchange on the web.

Why use a tree view for XML?

XML data is naturally hierarchical, or tree-like. A tree view is the most intuitive way to visualize this structure. It allows you to see the parent-child relationships between elements and easily navigate through deeply nested data, which can be very difficult to do in a plain text editor.

Can this tool handle very large XML files?

This tool runs entirely in your browser. While it is optimized for performance, very large XML files (many megabytes in size) may cause the browser to become slow or unresponsive. It is best suited for files of a reasonable size that you need to quickly inspect or debug.

What happens if my XML is invalid?

If the input text is not well-formed XML (e.g., it has mismatched or unclosed tags), the tool will display an error message, and the tree view will not be rendered. This can be a useful way to quickly check if your XML syntax is correct.

Is my XML data sent to your servers?

No. All parsing and rendering of your XML file happens locally in your web browser using JavaScript. Your data is never sent to our servers, ensuring your information remains completely private and secure.
