What Is An XML Formatter?

An XML formatter is a tool that takes compact, messy or difficult-to-read XML and converts it into a clean, indented and readable structure. This makes XML easier to inspect, debug, share and maintain.

Why Format XML?

XML is commonly used for APIs, configuration files, integrations, RSS feeds, sitemaps and enterprise systems. Formatting XML makes nested elements, attributes and data relationships easier to understand.

XML Formatting Example

Before Formatting

<person><name>Jane</name><city>London</city></person>

After Formatting

<person>
  <name>Jane</name>
  <city>London</city>
</person>
