XML Formatter

How to Use XML Formatter

1. Paste your XML code. Insert any XML document — a sitemap, RSS feed, configuration file or data export.
2. Choose your operation. Select Format to indent and beautify the XML, Minify to compress it to a single line, or Validate to check for syntax errors like unclosed tags or invalid characters.
3. Click Process. The tool formats or validates the XML instantly. If validation fails, it highlights the error line and column to help you locate the issue quickly.
4. Copy or download. The output is displayed in a clean text area. Copy it to clipboard or download it as a `.xml` file for direct use.

Benefits of XML Formatter

• Tidies up messy, machine‑generated XML (like sitemaps) into a readable structure with proper nesting and indentation.
• The validate function catches broken XML before you upload it to a production system, saving debugging time on errors that could break parsers.
• Minify mode removes unnecessary whitespace to reduce file size for transmission without altering the data.
• Completely offline — your XML data is processed locally and never leaves your browser.

Frequently Asked Questions

What counts as a valid XML document?

A valid XML document must have a single root element, properly closed tags, case‑sensitive tag names, and properly escaped special characters like `<` and `&`. The validator checks all these rules.

Can I format very large XML files?

The tool works well for files up to a few megabytes. Extremely large files (100MB+) may cause the browser tab to slow down. For huge datasets, consider splitting the file.

Does the formatter change XML attributes or order?

No, it preserves all element attributes, their order and values. Only whitespace between tags is normalised for indentation.

Is XML Formatter free and private?

Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
