Inspired by fixing historical redirects, this sheet uses the Wayback Machine API inside Google Sheets to surface URLs that may need redirects after a redesign or replatform.

How the sheet works

  • Enter a domain (domain.com, subdomain.domain.com, or www.domain.com/sub-folder/)
  • Set Date From and Date To to pull URLs from the Wayback index
  • Filter to Just HTML or show All asset types

Reading the sheet

  • Time Stamp: archive date in yyyyMMddhhmmss format
  • Wayback Machine URL: URL from the archive index
  • Mime Type: HTML, CSS, JS, etc.
  • Current Status: status chain such as 301 > 200 or 301 > 404
  • Final URL: current destination of the archived URL

Sheet limitations

The API pulls up to 20,000 rows. Large date ranges can slow the sheet; try smaller ranges if performance suffers.
