Why Format XML?

How It Works

Our XML formatter processes your data with these steps:

Parse XML

The input is parsed to ensure it's well‑formed XML. Invalid XML will not be formatted.

Apply Indentation

Each level of nesting is indented with the number of spaces you selected.

Output Readable Data

The result is a beautifully formatted XML structure, ready for inspection or editing.

Makes configuration files self‑documenting
Improves accuracy when copying data between systems

An XML formatting example, and a limit

Paste this one-line document and choose 2 spaces:

<catalog><item id="14"><name>Ceramic cup</name></item></catalog>

The nested item and name elements are placed on indented lines. The implementation uses the HTML beautifier on the text you paste, so the result is for reading. It is not a schema check and it will not add a missing XML declaration.

An unclosed tag or an illegal character is still invalid after indentation. Open the formatted result in an XML-aware editor if the document must be exchanged with another system.
