The owner of a Google Sheets can tick off the option: "Viewers and commenters can see the option to download, print, and copy"
.
However in this option, Google does not explicitly say that viewers cannot copy.
How are they able to copylock a spreadsheet and is there a way to bypass and copy anyway?
Here is a test spreadsheet:
https://docs.google.com/spreadsheets/d/1DLeK4X4MFbQe6X6lcbE_O-rTdy3MHApZEu1HhUWIji4/edit#gid=0
You are not able to directly copy the sheet, but there are a couple workarounds:
Copy cells values from the formula bar. (If the cell has a formula, it will copy the formula,not the actual value).
Copy values to another document using formula or Google Apps Script.
Formula
importrange("YOUR-ID","Sheet1!B2")
Script
function getData() {
var data = SpreadsheetApp.openById("YOUR-ID").getSheets()[0].getRange("B2").getValue();
console.log(data);
}
