There isn't something 'Quick'....initially. But you can import the sheet to a table that parsed all the data out correctly. IF the spreadsheet stays the same, you only have to set it up once with a script, and attach it to a button.
If the rows are arbitrary (?), I would create a sheet on the SS to paste them into, or auto enter thru a calculation, and import just that sheet
It also possible to Import only specific rows from Excel, if you "name" them (in Excel) as a "group". That "name" will then show up as an option, in the FileMaker Import. That method is needed if the Excel is different pieces in it, i.e., not really a database.
You could also do your copy/paste, if you pasted into a (large) text field (could be a global), then parsed it out. Or you could paste it in, then Export it out (as tab-separated text). It does save the tabs in the text, so it may be a decent Import. That is all if your need to "manual copy/paste".
You can also paste such data into a global text field and then use a script--which can be performed by the OnObjectModify trigger to create a new record for each row of pasted data and to parse the pasted row of data into a specified set of fields. This can come fairly close to mimicing the behavior of a spreadsheet but please keep in mind that a FileMaker is NOT a spreadsheet and should not be forced to become one--it's simpler to stick with Excel, Numbers or Google Sheets if that's what you really wanted anyway.
