About this utility
How to use Sitemap XML Validator
Validate sitemap URL sets and indexes, summarize dates and hosts, and flag duplicates or protocol-limit problems.
What to provide
Paste sitemap XML. External sitemap links are listed but never fetched.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Type, URL count, hosts, last-modified range, duplicates, and validation findings.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Linked sitemap indexes, redirects, robots policy, HTTP status, and canonical tags are not fetched or verified.
