Redirect Mapping CSV Builder
Pair old URLs with new destinations and generate a clean redirect mapping CSV for migrations, redesigns, and cleanup projects.
Build a clean redirect map for migrations
Site migrations and redesigns live or die on the redirect map — pair every old URL with the right new destination or you lose rankings and strand visitors on 404s. This builder lets you match old URLs to new ones and generates a clean redirect-mapping CSV, the format most platforms and developers expect for implementing bulk redirects.
Having the mapping in one tidy file makes the migration reviewable and repeatable: you can sanity-check every pairing, hand it to a developer, or import it into a redirect manager. It turns the riskiest part of a relaunch into an organized checklist.
Private and instant
The mapping is built entirely in your browser, so your URL structure — old and new — stays on your device. Copy or download the CSV when the pairings are complete.
Frequently Asked Questions
What is a redirect mapping CSV?
It is a spreadsheet-style file that pairs old URLs with their new destinations and a redirect status, usually 301 for permanent moves.
When should I use this?
Use it during redesigns, domain moves, CMS migrations, or URL cleanup projects before old pages disappear.
Does this create server rules automatically?
No. It creates a clean CSV plan your developer can convert into server, CDN, CMS, or hosting redirect rules.
Is the tool private?
Yes. URL mapping happens entirely in your browser.
