Paste the 404 / 301 list from the Internal Link Auditor, a spreadsheet, or any old_url | new_url CSV. Emits a Netlify _redirects block, an Apache .htaccess RewriteRule set, an nginx location block, a sed patch for bulk in-HTML link updates, and an IndexNow payload so Bing picks up the change within minutes.
Accepted formats (auto-detected per line): old_url | new_url · old_url,new_url · old_url · or a single URL (treated as a 404 to clean up). Lines starting with # are comments.
