When copying a sheet within the file, you can use the "Duplicate" command. When copying a sheet to a new file or an existing file, you need the "Copy to" command, which is the same as "Move and Copy" from Microsoft Excel.
Step 1: Open the workbook and right-click the tab name;
Step 2: Click the "Copy to" from the dialog box;
Step 3: Select "New spreadsheet" if you want the sheet as a single file, otherwise to select "Existing spreadsheet";
Step 4: You will get a message when the new file is ready;
Step 5: Please note that the newly created document has the name of "Untitled spreadsheet", please change the name by following how to name or rename a Google spreadsheet.
This method doesn't match the article title. It shows how to "copy," not "move," a tab to a different file.
Agreed. But thankfully you just have to delete the tab in the original file and rename the tab in the new file to effectively move it. Extra steps, but so much better than copy/paste or manually rebuilding it.
