XML Sitemap Generator

Developer notes

• metadataMode controls which child tags appear under each <url> — form defaults apply unless a CSV row overrides that URL. • Upload .csv with url,lastmod,changefreq,priority columns for per-URL metadata. • duplicatePolicy remove dedupes after normalization; sortUrls orders output alphabetically by loc. • Trailing slashes on paths are stripped automatically; http→https is never auto-upgraded — warnings only. • Pair with the Robots.txt Generator sibling and reference the file with a Sitemap: line at deploy time.

Options

• URL metadata

  Controls optional <lastmod>, <changefreq>, and <priority> children. Default values come from the Metadata defaults form section.

• XML formatting

  Pretty adds indentation for human review; compact minimizes bytes while staying valid XML.

• Duplicate URLs

  Remove drops duplicate loc values after normalization; keep emits every pasted line as its own <url> entry.

• XML header comment

  When on, adds a leading comment with URL count and a local-generation hint.

• Sort URLs A→Z

  When on, sorts <url> entries alphabetically by loc instead of paste/upload order.

When this is the right tool

• Ship a static site or JAMstack app when you already have a routes/build URL list. • Draft a staging sitemap without installing a crawler SaaS. • Generate a first sitemap.xml from a CSV export before splitting into index files offline.
