What this tool does

XML Formatter makes compact XML easier to read by adding indentation and structure.

Use it for SOAP payloads, RSS feeds, sitemap snippets, app configuration, integration responses, and XML examples.

XML is stricter than HTML, so missing closing tags, invalid nesting, and broken attributes should be fixed before reliable formatting.

The formatter runs locally in your browser for normal tool usage.

When to use XML Formatter

• Inspect SOAP, RSS, sitemap, and integration responses.
• Convert XML into JSON for easier application debugging.
• Format nested markup before review or documentation.

Limitations and safe-use notes

• Very large inputs depend on your browser memory, CPU, and device performance.
• The tool is designed for developer workflows, examples, configs, exports, and debugging, not for replacing security-critical internal systems.
• Avoid pasting production passwords, private API keys, medical records, financial records, or regulated customer data unless your policy allows it.

Common mistakes and warnings

• XML is strict about closing tags and quoted attributes.
• Whitespace can matter inside text nodes, so formatting should preserve text content.
• Namespaced XML may need careful handling when converting to other formats.

Privacy and browser processing

This page is static and the tool runtime runs on your device. Heavy work is sent to a browser Web Worker where possible. Local file loading uses the File API, generated downloads use Blob URLs, and no online save or share-result feature is included because that would weaken the privacy promise.

For normal tool usage, your pasted text or loaded file content is not sent to a server by this tool. This makes the page safer for formatting, converting, validating, or inspecting developer data that you do not want to upload elsewhere.

You can check this yourself by opening your browser developer tools, using the Network tab, and watching requests while processing sample input. See the verify no upload guide for step-by-step instructions.

Frequently asked questions

Is my XML uploaded to a server?

No. XML Formatter runs locally in your browser for normal tool usage. The static website files are downloaded by the browser, but your pasted input and selected local files are not uploaded to a backend for processing.

Can malformed XML be formatted?

Malformed XML must usually be fixed before it can be formatted reliably. Missing closing tags or invalid attributes can prevent parsing.

Does formatting XML change text content?

The formatter should preserve text values, but whitespace-sensitive XML should always be reviewed after formatting.

Can I format XML with attributes?

Yes. XML attributes are supported, and available options can control how attributes are handled.

Can I copy or download the result?

Yes. After a result is generated, you can copy it to the clipboard or download it as a local file using browser APIs.
