Question

例如，我怎样才能找到更快的公式？

=SUMPRODUCT((Data!D:D="RC Corp")*(Data!AD:AD="Expected Allowances / Provisions"))

Vs的

=COUNTIFS(Data!D:D,"RC Corp",Data!AD:AD,"Expected Allowances / Provisions")

将两个字段合并到一个新列并执行

 Z1 = D1&AD1
=Countif(Data!Z:Z,"RC CorpExpected Allowances / Provisions")

Vs VBA

Dim i as integer
Dim Total as integer
Total = 0 
i=0
While i < 1000 
    IF Range("D"&i).Value = "RC Corp" AND Range("AD"&i).Value = "Expected Allowances / Provisions" Then
Total = Total + 1
End If 
Wend
Range("$A$1").Value = Total

Answer 1

从evocandy的回答中醒来，我想出了这个基本代码。

time1 = Timer
Range("A1").Calculate ' Or the cell containing the Formula I want. OR use Sheets("Sheet1").Calculate for the calculation including concated columns
time2 = Timer

CalculationTime = Time2-Time1

为了使其工作，我必须将样本数据隔离到新的空工作表并禁用Excel中的自动刷新，以确保它不会计算任何其他计算。

Answer 2

在VBA中，您可以使用Timer。

放

time1 = Timer
'Your code
time2 = timer

totaltime = time2-time1
