XML Formatter

XML Formatter is for making dense XML easier to inspect when nesting, attributes, or closing tags are hard to review in a compact block. It is useful for feeds, configuration files, SOAP payloads, and markup exports where structure matters as much as raw text. The page is most helpful when you remember that formatting is not the same thing as domain validation. A nicely indented XML document can still violate schema expectations, include the wrong values, or break a downstream system if the source content itself was incorrect.

Do not paste sensitive production secrets into online tools.

Tool Interface

Format XML into readable indented output.

Input

Output

How this tool works

Paste the XML into the input area and make sure no extra prose surrounds the markup.

Run the formatter so nested tags, attributes, and repeated nodes are indented into a readable shape.

Review the output for broken tag structure, misplaced attributes, or escaped characters before copying it elsewhere.

Examples

Sitemap review

Format an XML sitemap response so you can inspect the URL entries, tag nesting, and overall file shape more easily.

Integration payload check

Beautify a SOAP or legacy XML payload before comparing it against a vendor's expected request structure.

Visual walkthrough

Tag hierarchy

The formatted output should make parent-child relationships clear enough that you can follow the markup path without manually counting brackets.

Attribute review

Check repeated nodes and attribute values after formatting because that's where integration mismatches often hide in dense XML.

What to verify before using the result

OKCheck whether the input is well-formed before trusting the formatted output, especially around closing tags, attribute quotes, and nested elements.

OKReview namespaces and attributes after formatting because those details are easy to miss in compact XML but still matter to the destination system.

OKAvoid pasting sensitive configuration data or private feeds if a safer local workflow is available.

OKValidate the final XML in the system or schema that will actually consume it rather than assuming indentation alone proves correctness.

Limitations

!Readable indentation does not guarantee that the XML matches a required schema, namespace expectation, or vendor contract.

!Malformed XML may still fail if tags, entities, or attribute quoting are broken.

!The tool improves inspection but does not transform XML into another data model automatically.

Parsing and handling notes

iNormalizes XML indentation for readability while preserving the logical structure of the markup.

iBest for inspection and communication, not for full schema validation or XSLT-style transformation work.

FAQ

Should I paste production secrets into this tool?

No. Even when a page works locally in the browser, production secrets, tokens, private keys, and confidential payloads should be sanitized or avoided.

What is this tool best used for?

Making XML readable enough to inspect nesting, attributes, and structural errors without opening a heavier editor first.

Does the output still need to be tested elsewhere?

Yes. Formatting, decoding, or minifying can make text easier to inspect, but the final result still needs validation in the real app, parser, or deployment workflow.

What mistake should I watch for most?

Mistaking well-formatted XML for schema-valid XML when real integrations often depend on more than indentation and tag balance.
