Notes

  • Formula examples are preserved from maintained workbook usage and normalized to the current U. prefix.
  • Complete formulas demonstrate working patterns; they do not imply that undocumented option values are supported.
  • Where maintained sources do not specify every accepted value, default, or error message, this page does not infer one.
  • For functions that perform actions, use a visible trigger or supported block/throttle parameter to avoid unintended repetition during recalculation.
