Is There a Simple Tool or Script to Batch Convert Hundreds of Old URLs Into New Redirects?

[hiwesuc]

Hello everyone.

Our company recently relaunched our website with a completely new URL structure and we now have hundreds of old URLs that need to be mapped and redirected to their new equivalents. Manually creating each redirect rule is taking forever and we are worried about missing some.

Is there a tool, script, or automated method that can help batch convert and map old URLs to new ones efficiently? We are using an Apache server so .htaccess redirects are an option but we need help generating them at scale.

Has anyone handled a large scale URL migration like this and what workflow did you follow?

A reliable URL converter can map every old URL to its new equivalent automatically without manual work.

thanks in advance for any help

Done this a few times — keep it simple, pick based on your URLs:

1. If there's a pattern (e.g. /vehicle/x → /car/x), one rule covers everything:

RewriteRule ^vehicle/(.+)$ /car/$1 [R=301,L]

2. If the URLs are random 1-to-1 (no pattern), put them in a CSV (old_url,new_url) and generate the rules with a tiny script instead of typing them by hand:
Redirect 301 /old-page /new-page

Two quick tips:
- Crawl the old site first (Screaming Frog or wget --spider) so you don't miss any URLs.
- Always use 301 (permanent) so SEO carries over.

That's really it — pattern = 1 rule, random = CSV + script.
