Google Sheets has an IMPORTRANGE function that allows you to import a range of cells from another spreadsheet and requires you to enter the spreadsheet's URL.

But what if you just want to reference data from another sheet within the same spreadsheet?

A simpler approach is to use the QUERY function instead.

A Quick Example

We can use this formula to pull the values from columns A and B of Sheet1:

=QUERY(Sheet1!A:B)

Here's the data in Sheet1:

We'll enter the formula in row 4 of Sheet2 to display the data from Sheet1 starting from that row:

When you add new rows to Sheet1, they'll automatically be added to Sheet2 as well since we're referencing the entire A and B columns.

As you can see from the example, this is a much simpler method if you just need to reference data within the same spreadsheet.  You no longer have to think about the spreadsheet URL and having to update it if you make a copy of the spreadsheet later (which will have a different URL).
