Example
XML Editor: input and output
A two-track playlist fragment, dense enough to paste straight from an API response into the editor.
<?xml version="1.0" encoding="UTF-8"?><playlist name="Focus Mix"><track><title>Clair de Lune</title><artist>Debussy</artist><seconds>300</seconds></track><track><title>Gymnopedie No.1</title><artist>Satie</artist><seconds>180</seconds></track></playlist><?xml version="1.0" encoding="UTF-8"?>
<playlist name="Focus Mix">
<track>
<title>Clair de Lune</title>
<artist>Debussy</artist>
<seconds>300</seconds>
</track>
<track>
<title>Gymnopedie No.1</title>
<artist>Satie</artist>
<seconds>180</seconds>
</track>
</playlist>Both <track> elements — different title, artist and duration — expand into identical structures once formatted, which makes comparing them line by line easy after an edit.

A real XML editor in the browser
Editing XML in a plain textarea means counting tags by eye. This editor gives you the Monaco engine with XML language support: tag and attribute coloring, bracket matching, folding regions for collapsing elements, multi-cursor editing, and find & replace with regex — the desktop editing experience with zero install.
Around the editor sits the full workbench: format at your preferred indentation, validate with exact positions, explore documents as a collapsible tree, load files by drag & drop or URL, and export the result with one click.
| Action | Shortcut |
|---|---|
| Find | Ctrl/⌘+F |
| Find and replace | Ctrl/⌘+H |
| Add next occurrence to selection | Ctrl/⌘+D |
| Add a cursor at click point | Alt+Click |
| Toggle line comment | Ctrl/⌘+/ |
| Fold element at cursor | Ctrl/⌘+Shift+[ |
| Unfold element at cursor | Ctrl/⌘+Shift+] |
| Fold all | Ctrl/⌘+K, Ctrl/⌘+0 |
| Unfold all | Ctrl/⌘+K, Ctrl/⌘+J |
| Undo / redo | Ctrl/⌘+Z / Ctrl/⌘+Shift+Z |
Editing XML safely
Everything stays in your browser, so production configs and payloads with secrets are safe to edit here. Work in the standard loop: format first for readability, edit, validate before export — the loop that catches every accidental tag break before it reaches a parser. Validate with the XML validator before export, and compare the edited file with the original in the XML diff.

Frequently asked questions
Everything you need to know about the XML Editor.
01How do I use the XML Editor?
Type or paste XML into the editor — highlighting and folding work as you type. Format to clean up, Validate to check well-formedness, flip to Tree view to inspect structure, then download your result.
02Can I edit large XML files here?
The editor is Monaco — the engine inside VS Code — built for big documents: folding collapses regions you're not working on, find & replace handles bulk edits, and multi-megabyte files stay responsive on a modern machine.
03Which keyboard shortcuts work in the editor?
The Monaco/VS Code set: Ctrl/⌘+F to find, Ctrl/⌘+H to find and replace, Ctrl/⌘+D to add the next occurrence to a multi-cursor selection, Alt+Click to add a cursor at a specific point, Ctrl/⌘+/ to toggle a comment, and Ctrl/⌘+Shift+[ / ] to fold and unfold the element under the cursor.
04Can I validate against an XSD in the editor?
This editor checks well-formedness only — matched tags, proper nesting, legal characters — the same layer the [XML validator](/xml-validator) checks. Schema validation (XSD/DTD) needs the schema file and a dedicated validator such as xmllint or a Java/.NET runtime; paste the well-formed result there once this page confirms the markup itself is sound.
