Does the XML formatter send my data anywhere?

No. Parsing, validation, and serialization all run in your browser with a small custom tokenizer. Your document never leaves your device, which matters for API responses, configuration files, and anything covered by an NDA.

What counts as a parse error?

Unclosed tags, mismatched close tags ( ), unterminated comments (no "-->"), unclosed CDATA sections, and malformed processing instructions. Well-formed XML with unknown element names or missing schemas is still accepted — this tool validates syntax, not schemas.

How does minify differ from just stripping whitespace?

Minify drops whitespace that exists only between tags for readability, but preserves text content inside elements exactly as written. That means Alice stays with its spaces because the whitespace is part of the element value, not indentation.

Does the tool support namespaces, comments, and CDATA?

Yes. XML namespaces (xmlns:foo attributes), comments ( ), CDATA sections ( ), processing instructions ( ), and DOCTYPE declarations are all preserved through format and minify. Empty elements collapse to the self-closing form.

How to pretty-print and validate XML with MakeMyTxt

Paste any XML document to pretty-print or minify it. Malformed markup is reported with the exact line and column of the problem.

Open the XML Formatter
Go to makemytxt.com/xml-formatter — the page is static, opens quickly, and does the formatting work in your browser once it has loaded.
Paste your XML
Drop in an RSS feed, a SOAP payload, an Android layout, a Maven pom.xml, or anything else built from tags. Parsing happens in your browser with a small tokenizer — nothing is uploaded.
Choose pretty-print or minify
Pretty-print with two or four-space indentation puts each element on its own line for easy review. Minify strips all inter-tag whitespace so the payload is as compact as possible for storage or network transfer.
Copy, download, or fix errors
If a tag is unbalanced or a declaration is malformed, the line and column of the failure are shown so you can jump straight to the problem. Otherwise copy the output or download it as a .xml file.

Frequently asked questions

Does the XML formatter send my data anywhere?: No. Parsing, validation, and serialization all run in your browser with a small custom tokenizer. Your document never leaves your device, which matters for API responses, configuration files, and anything covered by an NDA.
What counts as a parse error?: Unclosed tags, mismatched close tags (<a></b>), unterminated comments (no "-->"), unclosed CDATA sections, and malformed processing instructions. Well-formed XML with unknown element names or missing schemas is still accepted — this tool validates syntax, not schemas.
How does minify differ from just stripping whitespace?: Minify drops whitespace that exists only between tags for readability, but preserves text content inside elements exactly as written. That means <name> Alice </name> stays with its spaces because the whitespace is part of the element value, not indentation.
Does the tool support namespaces, comments, and CDATA?: Yes. XML namespaces (xmlns:foo attributes), comments (), CDATA sections (<![CDATA[ … ]]>), processing instructions (<?xml …?>), and DOCTYPE declarations are all preserved through format and minify. Empty elements collapse to the self-closing <tag/> form.
