How many child sitemaps can the converter handle?

xmlsitemapmaker.com follows up to 50 child sitemaps per sitemap-index by default, fetched in parallel. That covers the vast majority of real-world sites — most large sites split content into 5–20 child sitemaps. For sites with hundreds of children (huge e-commerce catalogs, multi-locale platforms), download each child sitemap separately and run multiple conversions, then concatenate the CSVs. Each individual sitemap is bounded to 25 MB per fetch. The 50-child limit exists to keep one conversion request well within Cloudflare Workers' subrequest budget; on a paid plan with concurrency limiting we can raise that to 200+ in a future release. If you hit the cap, the preview shows how many children were successfully fetched.
