#GETTING_DATA is a temporary message shown while a large or complex workbook recalculates, or while an add-in / data type fetches values. It usually clears on its own.
Wait for calculation to finish
Let the recalculation complete; the value replaces the message.
Reduce volatile formulas
Trim volatile functions (NOW, OFFSET, INDIRECT) that force constant recalculation.
No — it's a transient status during calculation or data fetch, not a failure.
