Guide
How to use this tool
- 1
Paste your XML document
Add the XML content you want to format, minify, or check.
- 2
Choose the transformation
Use formatting for readability or minification to remove unnecessary whitespace.
- 3
Fix issues and reuse the result
If an error is reported, correct the XML before copying the final version.
Tips and best practices
- A well-formed XML document must keep elements properly nested and every opened tag correctly closed.
- Minification removes whitespace and line breaks but does not intentionally change the logical structure.
- If your XML must satisfy an XSD schema or application-specific rules, validate it with the target system as well.
Frequently asked questions
Does the formatter automatically repair invalid XML?
No. It can report detected problems, but invalid XML must be corrected before it can be formatted reliably.
What is the difference between formatting and minifying XML?
Formatting adds consistent whitespace for readability, while minification removes unnecessary spaces and line breaks.
Does formatting change tags or values?
The goal is to change presentation only, without intentionally modifying the document structure or data.
Is my XML uploaded to a server?
No. Processing runs locally in your browser.
