How to convert a PDF to a Google Sheet which I deleted and is in my MacBook Air trash to a functional Sheet & save into Google Drive where I can continue to use it as a fully functional Sheet?
Since you have the PDF of the sheet you could try to upload the file to your Google Drive by going to drive.google.com and clicking the "New" button in the top left corner of your screen. The tap "File Upload" and upload the PDF to your Drive.
Next, highlight the whole PDF that should now be in your Drive, open a new Google Sheet, and paste the whole thing there. It should be fully functional now, with everything from the PDF now in the Sheet.
