METHODHow this tool works
Validates language-tag syntax and URLs, then generates escaped alternate links.
Enter language code | url, one per line. Update the result, inspect it, then copy or download the output. Reset restores the example inputs so you can start a new calculation.
BEFORE YOU USE THE RESULTAssumptions & limitations
Every language version should reference the same set, including itself. Syntax checks do not verify regional targeting or reciprocal tags.
The tool does not connect to your website, change your hosting or install anything in WordPress. Any output must be applied separately in the intended environment.
