Sitemap Validator
Paste sitemap XML to check basic structure before submitting it to search engines.
How to use
- 1
Paste sitemap XML.
- 2
Run validation.
- 3
Review basic structure results.
Quick answer
Sitemap Validator analyzes pasted XML data to verify that your sitemap structure conforms to official schema definitions. It is best for catching unclosed XML tags, counting total URLs, and validating index file layouts.
Key features
- Checks structural XML validity and spots tag nesting, bracket mismatch, and encoding errors.
- Extracts and counts all standard URL nodes and lastmod timestamps from the sitemap.
- Supports validating sitemap index structures alongside standard URL-set structures.
- Runs completely in-browser, preventing your site's full URL catalog from leaking to server logs.
- Displays real-time line numbers and detailed syntax error logs when parsing fails.
- Requires zero signups, email submissions, billing details, or site linking.
About this tool
An XML sitemap is a site's blueprint for search engine crawlers, telling them which pages are ready to index and when they were updated. If your sitemap contains malformed XML tags, missing namespaces, or incorrect nesting, Google Search Console will reject it entirely—delaying your index. This Sitemap Validator parses raw XML directly inside your browser tab to confirm it adheres to official sitemap specifications. It reports total page counts, indexes nested links, and pinpoints exactly where any structure conflicts lie. Because verification occurs client-side, your unpublished page maps and site structures remain completely private.
Common scenarios
Checking custom exports
Test custom database sitemap queries and exports to verify all tags are closed and namespaces are declared correctly.
Auditing index files
Analyze primary sitemap index files to ensure child sitemap links are structured according to standard protocol.
FAQ
Does this crawl every URL?
This tool checks XML structure and sitemap entries. Live URL crawling would require a separate server-assisted check.
Can it validate sitemap indexes?
Yes. It checks both URL sets and sitemap index entries.
What common XML errors does it check?
It checks for missing namespace declarations, unclosed tags, malformed date/time strings, unescaped special characters (like unescaped ampersands), and missing mandatory elements like loc tags.
Is there a limit on the sitemap size I can paste?
There is no fixed limit, but pasting extremely large files with tens of thousands of links can lag standard text boxes. For very massive sitemaps, we recommend checking chunks or using local offline XML validators.
Is my site's directory safe?
Absolutely. All XML parsing is processed locally in client-side memory using JavaScript. Your site URLs are never sent to a server, logged, or recorded.
Can it check robots.txt lines too?
This tool is strictly for XML sitemaps. Use our dedicated Robots.txt Tester to audit rules, user-agent directives, and crawl paths.
