Question 1

How do I format or beautify XML online?

Accepted Answer

Paste or type XML, and the output updates automatically after a brief pause. Choose two spaces, four spaces, or tabs to control indentation; use Format XML to format on demand. The formatter preserves element names and text values, and reports XML syntax errors instead of returning misleading output.

Question 2

Can I validate XML and find the error line?

Accepted Answer

Yes. Select Validate to check whether your XML is well-formed without changing the output. When the browser parser provides an error location, the tool shows the line and column and lets you jump to the reported line in the input. This does not validate an XML document against an XSD or DTD schema.

Question 3

Does minifying XML remove comments or change text?

Accepted Answer

Comments are preserved. You can choose whether minification removes whitespace-only text nodes between elements. That option may change meaningful whitespace in some XML vocabularies, so turn it off when preserving all text nodes matters.

Question 4

Is my XML uploaded or saved?

Accepted Answer

No. XML is parsed and formatted in your browser. The tool does not upload, store, or automatically save your input. Download the result if you want a local copy.

Question 5

Does the XML editor support syntax highlighting and full screen?

Accepted Answer

Yes. XML tags, names, attributes, quoted values, comments, declarations, CDATA, and entities are color-coded in both editors. Select Enlarge above the output to make it taller, or Full screen to expand the formatter workspace.

Question 6

Is there a file size limit?

Accepted Answer

The tool accepts input and XML files up to 2 MB to keep browser processing responsive.
