I was wanting to change the permalink structure on a large website that had been running for 8 years. This plugin made it so easy. Just run before changing the structure and run again after changing structure. Ensure you include URLs and post/page names in both files. Match up the outputs and you instantly have your redirections sorted with no effort at all!

The download to computer feature didn’t work. But the ‘show results here’ worked fine, enabling me to copy and paste the output into a spreadsheet.

Thanks++ to the developer. Saved me loads of work.
