What this tool does
Sitemap URL Auditor gives SEO and engineering teams a fast local check for sitemap hygiene. Paste a `urlset` or `sitemapindex` XML file and the tool extracts loc, lastmod, priority, and changefreq values, then reports total URL count, sitemap index entries, HTTP URLs, query-string URLs, missing lastmod values, stale lastmod values, future dates, duplicate loc values, trailing-slash canonical conflicts, and extension distribution.
It is designed for the common workflow where a sitemap has just been generated and someone needs to sanity-check it before submitting to search engines or shipping a site migration. Markdown output is good for review notes, CSV output gives the URL inventory, and JSON output keeps the metrics structured.

Real-world use cases

Export the URL inventory as CSV and compare extension or path patterns during a migration.
Common pitfalls
This tool does not fetch URLs, so a clean sitemap report does not prove every page returns 200.
Query parameters may be valid for some sites, but they deserve explicit review.
Privacy
Sitemap analysis is local. Private staging URLs or unpublished paths may appear in reports.
