A named range gives an address a meaningful label, but the name must still point to the intended cells. A readable formula is only as reliable as that definition.
Create and inspect the name
Select the desired cells and choose Data > Named ranges. Enter a descriptive name, verify its sheet and address, and save it. For example, =SUM(monthly_costs) can refer to a checked named numeric range.
Google’s naming rules allow letters, numbers, and underscores, with restrictions including no leading number, spaces, or A1-style name. Keep the label distinct from similar business measures.
Repair definitions before formulas
If a formula reports an unknown or invalid name, inspect the named-range panel. Check whether the name was deleted, renamed, or redirected to another address. Preserve its previous purpose before creating a replacement.
Edit the existing definition when the same logical range should move. Avoid creating several nearly identical names as trial fixes. Named ranges and table structured references are different features, so use the appropriate syntax for each.
Check dependent behavior
Compare a known subtotal and inspect range boundaries after adding data. A name does not by itself promise that every newly pasted row will be included. Test the actual insertion workflow used by the team.
Deleting a named range breaks formulas that reference it. Google notes that protected ranges referring to a named range can continue using the cell range, so deletion should not be treated as removing edit protection. Review formula dependencies and permissions separately. Keep a short description of each important name’s population and units so future editors can distinguish a valid address from a semantically incorrect one.
