Why did formula cells become null even though Excel shows values?

Sparkflows explicitly checks for Excel formula errors:

  • #DIV/0!

  • #N/A

  • #VALUE!

  • #REF!

  • #NUM!

  • #SPILL!

Any such value is converted to null.


Why this is intentional

Excel visually hides errors behind formatting.
Sparkflows exposes them as missing data instead of corrupting columns.
