XML Tools

Indent XML by 2, 4 or 8 spaces or tabs, wrap long start tags, and keep xml:space="preserve" subtrees exactly as they were. Free, and in your browser.

Every XML error reported with its position and a plain-English reason: which element was left open, which closing tag was found. Free, in your browser.

Type a path, see the matches as you type, and get a readable error when the engine hits an axis or function it does not implement rather than an empty result.

Point it at the repeating element and get a table: one row per record, one column per leaf, attributes marked with @ — ready for a spreadsheet.

Element order, occurrence, required attributes, unknown attributes and built-in types with facets — reported against the node that broke the rule.

Indent XML by 2, 4 or 8 spaces or tabs, wrap long start tags, and keep xml:space="preserve" subtrees exactly as they were. Free, and in your browser.

Shrink a document for transport or a log line, with a per-change report of exactly what was removed and how much it saved — and mixed content left intact.

Catch what a validator cannot, because the document is still valid: mixed tabs and spaces, stale namespaces, a contradictory BOM. Free, in your browser.

Strip XML comments for a smaller payload or a cleaner diff, with a count of what was removed and CDATA text left intact. Free, and runs in your browser.

Put markup, SQL or HTML inside XML without escaping every angle bracket, and split the terminator correctly when the text contains one.

Escape or unescape XML entities both ways, with unknown entities reported instead of silently dropped. Free, private, and it runs in your browser.

Turn `café` back into `café`, drop the byte-order mark that breaks string comparison, and fix a declaration that says ISO-8859-1 while the bytes are UTF-8.

Line and column numbers for every row, so a message from a parser or a colleague ('line 214, column 9') points at the same place here.

See the shape of an XML document instead of its syntax: expand and collapse elements, read attributes, and copy the XPath to the node you clicked. Free.

Type a path, see the matches as you type, and get a readable error when the engine hits an axis or function it does not implement rather than an empty result.

The mapping a document actually declares, prefix by prefix, with the scope where each applies and the elements that use it.

List every `id`, `sku` or `href` in a document as a flat column — with duplicates highlighted and a count, ready to paste into a spreadsheet or a check script.

A quick profile of a document: how many of each element, how deep it nests, which names dominate, and where the bytes actually go.

A diff that understands documents: inserted records read as additions rather than shifting every line below, and reformatting is not a rewrite. Free.

Point it at the repeating element and get a table: one row per record, one column per leaf, attributes marked with @ — ready for a spreadsheet.

A readable YAML rendering of a document, using the @attribute convention and text keys, with types coerced only when every value agrees.

Concatenate XML exports into one document, reusing a wrapper or the first root, and record a source attribute on each part so origin is never a guess. Free.

Turn a batch export into one file per record, each still a valid document with its ancestors rebuilt around it and the file name taken from a key attribute.

Write or paste a stylesheet, watch the transform run as you type, and see the result rendered plus the exact serialized output.

Every XML error reported with its position and a plain-English reason: which element was left open, which closing tag was found. Free, in your browser.

Element order, occurrence, required attributes, unknown attributes and built-in types with facets — reported against the node that broke the rule.

Generate a starting-point XSD from one or two real documents: types from the values, minOccurs and maxOccurs from what repeats, required attributes. Free.

Content models, attribute types, required and fixed values, ID uniqueness and IDREF resolution — validated against the DTD as a real parser would.

Catch the mistakes that make a feed fail silently in readers: a missing channel link, duplicate GUIDs, an Atom date in an RSS pubDate. Free, in your browser.

See what a document asks a parser to do: external and parameter entities, external DTD, XInclude and billion-laughs patterns. Free, in your browser.

Build a request skeleton with header and body parameters, correct namespace prefixes, escaped values and the right transport header line for your SOAP version.
