How do I sort URLs in my sitemap CSV?

Open the CSV in Excel or Google Sheets, select the URL column, then Data → Sort A→Z (or Z→A for reverse). For sort by last-modified date, change that column type to TIMESTAMP first or it'll sort lexicographically. From the command line: sort -t ',' -k 1 sitemap.csv writes a sorted version. xmlsitemapmaker.com preserves the original order from the source sitemap by default — sitemaps often imply priority by listing URLs in a specific order (newest first, by depth, by lastmod), so the converter doesn't sort. If you want sorted output specifically, use the JSON export and pipe through jq, or sort the CSV after download.
