Importing a saved run into your account is coming soon. Until then, your last runs stay in this browser only, and you can download your files.
How to use
- Paste the full URL of each sitemap file, one per line, with an optional last-modified date after a comma.
- Tick the date option only if the files really changed today.
- Fix any warnings about hosts or file names.
- Download sitemap_index.xml, upload it to your site, and submit that one file.
What it checks and how it works
A sitemap index is an XML file whose root is sitemapindex and which lists sitemap files in sitemap/loc entries, as defined at sitemaps.org. You need one when a single sitemap would pass 50,000 URLs or 50 MB uncompressed, or when you want to group sitemaps by section. Google's guide says you can submit a single index file instead of every sitemap.
The tool writes the namespace, escapes the values and keeps the order you give. It does not open your sitemap files, so check each with the Sitemap Validator.

When one sitemap would exceed 50,000 URLs or 50 MB uncompressed, or when you prefer one file per section such as pages, blog and products.
