Importing Google Sheet as ingame PC sheet

How do I import this for a PC sheet?  It is also a multi page sheet and would like to be able to import all the pages.

There is no real way to import a google sheet to Roll20 to be used as a character sheet. You can import PDFs to Roll20, but they turn into images and wouldn't be interactive at all. Your best bet is to manually copy the stats of your character into a Roll20 character sheet, inside a game that have the relevant sheet template selected. (I.e. if it's a D&D 5E character you want to import, have your Roll20 game use the "D&D 5E by Roll20" character sheet template)

Unfortunately the game is based on Pathfinder rules but the current sheets do not reflect all and/or certain options related to the game.  The options are important and would need to be on a in game sheet.

Then you have to save that info in some notes section of the sheet or similar, or try the other sheet. There are two Pathfinder 1E sheet, one official, and one community-made.

As a Pro subscriber, you could also try making a copy of one of the Pathfinder sheets and modifying it to match your needs...you can create and use custom sheets. It requires a little HTML/CSS and possibly some JS knowledge, but if you don't know any of those, many of us sheet authors learned from creating our own custom sheets, so the languages aren't too inaccessible.  And if/when you run into problems, these forums are super helpful...
