XML Tools
XML keeps element order, attributes, namespaces, and mixed text in one document. Browse its tree to understand a feed, format markup for review, or validate syntax before converting it. These tools process the file locally in the browser.
Choose the right tool
XML Viewer
Use the tree to inspect repeated elements, attributes, and deeply nested sections in a long document.
XML Formatter
Use the formatter to make structured markup readable while keeping text-heavy and preserved-space elements inline.
XML Validator
Use the validator when a feed fails to parse and you need the reported location of a malformed tag or attribute.
XML to JSON
Use the converter when application code needs a JSON representation and you can review how attributes and text map.
All tools
XML Viewer
Inspect XML elements and attributes in a searchable tree.
Open tool →XML Formatter
Indent XML while preserving meaningful text and element order.
Open tool →XML Validator
Find XML syntax and namespace errors by line and column.
Open tool →XML to JSON
Turn XML elements and attributes into structured JSON.
Open tool →XML to YAML
Convert XML into YAML with explicit attribute keys.
Open tool →XML to CSV
Export repeated XML records as a flat CSV table.
Open tool →Example workflow: inspect an order feed
- Open the XML Viewer and find one order element, including its attributes and any repeated child elements.
- Run XML Validator before conversion so malformed markup does not obscure the real mapping issue.
- Convert a representative sample to JSON and compare its fields with the contract expected by the receiving application.
Before you use the result
XML and JSON express some information differently. This site's XML mapping uses @ for attributes and special text keys where needed; comments, processing instructions, and mixed content need special review. A valid XML document does not prove that it matches an XSD or a business schema.
Preserve what matters during conversion
An XML feed can contain data that is easy to overlook in a plain table. An order identifier may be an attribute while the customer name is element text. Repeated sibling elements can become arrays, but a single occurrence may have a different JSON shape. Before converting a production feed, test both one-item and multiple-item samples. The XML to JSON output is a practical data view, not a promise that a round trip will reproduce every XML feature.
Use XML to CSV only when the document has a clear repeated record element and the destination needs rows. CSV cannot represent arbitrary nesting, comments, or namespaces. Check the resulting header and a few records before importing. XML to YAML is better suited to a hierarchical output, but the same mapping review still matters.
Syntax checks and readable markup
The XML Validator checks whether markup is well formed. It is a first step when a parser rejects a feed, especially after manual edits to quotes or closing tags. It does not apply an external XSD. Use XML Formatter to inspect structure after syntax is valid. For text-heavy elements, avoid assuming that added whitespace is harmless; compare the result with the consuming system when text content has exact meaning.
