Format and inspect XML

For developers examining a feed or configuration file, XML Formatter makes nesting visible before corrections or review.

Indent an XML document to expose its structure and catch formatting problems before further work. You get the result directly in your browser.

How to use

Paste the XML into the input area or import a compatible file.
Run formatting to indent the document and expose its structure.
Read the result in the dedicated area and look for unclosed or badly nested tags.
Fix the source if needed, then run formatting again to check.

Example

A developer inspects an XML configuration file received from a partner. They paste the content, run formatting and immediately see the nesting levels. This helps them spot a missing tag before integrating the file into their application.

Limits and formats

The tool formats XML but does not replace full validation against a schema.
A very large document may slow down the browser or exceed its capacity.
Binary or badly encoded files may produce an unusable result.
Comments and significant spaces may be displayed differently depending on formatting.

Where processing happens

Everything runs in your browser: the document is parsed and indented locally. The XML content you provide is never uploaded, shared or stored.

Frequently asked questions

Does formatting change the data?

Formatting acts on spaces and indentation to make the structure readable. Tag names and text values are preserved, but you should check the result before replacing your original file, especially if whitespace matters in your workflow.

Can I format XML extracted from an HTML file?

The tool also accepts text, HTML and similar files. If the content is not well-formed XML, formatting may fail or produce a partial result. Check the nature of the document first before relying on the output.

Why is my valid XML rejected?

XML may look valid to you while containing a syntax error, such as an unclosed tag or a reserved character that is not escaped correctly. Fix the reported issue, then run formatting again to confirm that the structure is accepted.
