How it works
How to use the WSDL Formatter
Paste WSDL
Paste code, drop a file onto the editor, or load the sample.
Choose a style
Pick indentation and line width (and quotes/semicolons for JavaScript-like languages).
Copy the result
Syntax errors are highlighted with their line and column so you can fix them quickly.
About this WSDL formatter
This tool uses a validating XML formatter. Pretty-prints WSDL service definitions: types, messages, port types, bindings and services.
Formatting only changes whitespace and layout, never behaviour. Everything runs in your browser.
Built for developers
Why developers use it
Private by design
Runs 100% in your browser. Nothing you paste is uploaded, logged or stored on a server.
Instant results
Output updates as you type, with precise error locations when something is wrong.
Works offline
Once loaded, the tool keeps working without a connection. Install it as an app if you like.
Free, no sign-up
No accounts, no limits, no watermarks.
FAQ
Frequently asked questions
Does formatting change how my WSDL works?
No. Only whitespace, line breaks and similar layout details change.
Why does it report a syntax error?
The formatter parses your code first. Invalid WSDL is reported with the exact line and column.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
