Hi,
The result of the formula which combins of MID,LEFT & RIGHT functions is a string value not a date value. So the style of the cell does not effect.
And it seems you should change your formula to =IF(ISBLANK(INPUT!$A2),"",DATEVALUE(""&CONCATENATE(MID(DateConversion!A2,5,2),"/",RIGHT(DateConversion!A2,2),"/",LEFT(DateConversion!A2,4))))
Please try this fix. We support to parse this date format.
