U.UUID

Summary

Returns a Universally Unique ID (UUID) the first time the cell is calculated, and continues to return the same UUID on each subsequent recalculation

Syntax

=U.UUID(fromworkbook)

Parameters

Parameter Required Description
fromWorkbook Not stated Public source parameter; the maintained workbook does not provide a narrower description.

Behavior

The documented public interface is supported by the current U Add-in source signature and the maintained Usage Examples workbook. Optional parameters are shown in square brackets in the syntax above; omit the brackets when entering a formula.

Return Value

Returns the function result or action status described by the formula and parameters above. The maintained sources do not define a narrower, stable return contract for this function.

Examples

=U.UUID()

=IF(COUNTBLANK(B6:F6)>0,"",U.UUID())

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.
