move https:// and https://www of duplicate files to https:// with bulk import?

I want to use redirection to 301 redirect using the import option of a csv file to move 160 or so old html files to a new WordPress blog with the same core domain name but make it https.

But sadly I have some duplicate files, some https:// some https://www that I want to move to the WP site with https with a SSL installed and already coded all the urls and links with https://

So move both

https://example.com/old-stuff.html

AND

https://www.example.com/old-stuff.html

to

https://example.com/higher-ranking-keyword/

In his documentation
https://redirection.me/support/import-export-redirects/

it suggests doing it like this
https://example.com/addintheworkplacearticles.html/.*,https://example.com/manage-adhd-at-work/,1,301

But that’s just for one old file to one new file.

I have two old files that are basically the same but one is https:// only and one is http:/www

What is the right code for me to import both 160 old URLs and redirect it to one new https WordPress URL?

Thanks
