404 to 301 – Redirects Importer

404 to 301 – Redirects Importer is the official bulk-import add-on for the 404 to 301 plugin. It adds an Import panel to the Tools tab so you can load hundreds — or thousands — of custom redirects in one go, either from a CSV file you already have or directly from another redirect plugin you’re moving away from. Every redirect status the parent plugin supports (301, 302, 307 and more) is preserved on import.

Use it when you’re migrating a site, switching redirect plugins, restoring a backup, or rolling out a planned URL change across a large content set. Stop copy-pasting redirects one row at a time.

Why use Redirects Importer?

• CSV import — bring redirects in from a spreadsheet, a backup, or another tool that can export CSV.
• Plugin migration — import redirects directly from popular plugins:
  • Redirection by John Godley
  • 301 Redirects – Redirect Manager by WebFactory
• Smart matching — exact, prefix and regex matches are detected and preserved, so your existing rules keep behaving the same way.
• All redirect statuses preserved — 301, 302, 307 and the other codes the parent plugin supports come through intact, not flattened to 301.
• Safe by default — duplicate redirects are skipped, invalid rows are reported, and nothing overwrites your existing rules unless you choose to.
• Native integration — rows are written through the parent plugin’s own model, so hashing, audit events, hit counters and dedupe rules stay consistent with single-row creates.
• Free and unlimited — no row limits, no premium upgrade.

Built for the 404 to 301 workflow

This add-on is a light-weight companion to the parent plugin. It hooks into the existing Settings → Tools screen and re-uses the same database tables and validation rules, so imported redirects behave identically to redirects you create by hand.

• No new settings page — the Import panel lives inside the existing Tools tab.
• Requires the free 404 to 301 plugin (4.0 or newer).
• Same coding standards, security model and multisite behaviour as the parent plugin.
