Is there an option to import directly from pixelpost DB to wordpress

I’m not sure what you’re talking about.
This script imports everything from pixelpost db into wordpress.

I have sql file that need to be imported, not credentials from pixelpost which should be entered into wp admin panel

It won’t work with a SQL file alone, as it imports data directly from the DB. Import your SQL file in DB, then fill in your db settings in the script, this should work. Good luck!
