About Sitemap Formatter

A sitemap is an XML file that tells search engines which pages on your site are available for crawling. The Sitemap Protocol (sitemaps.org) defines the structure: a <urlset> root element containing <url> entries, each with a required <loc> and optional <lastmod>, <changefreq>, and <priority> fields. This formatter works on XML you paste into the browser, so it can format, minify, and validate sitemap structure without fetching external URLs.

How It Works

The tool formats XML that you paste into the browser. DOMParser parses the sitemap, the formatter serializes it with consistent indentation or minifies it, and the validator checks <urlset> or <sitemapindex> roots, required <loc> values, optional <lastmod> dates, <changefreq> values, and <priority> numbers from 0.0 to 1.0.

Common Use Cases

Formatting pasted sitemap.xml content
Checking sitemap XML structure before deployment
Validating loc, lastmod, changefreq, and priority fields
Minifying sitemap XML for review or storage
Detecting malformed XML in sitemaps
Reviewing URL coverage before SEO audits
