Excelにデータが入力されるまで数式を適用するときにセルを空白のままにするにはどうすればよいですか？

Excelでは、数式を列範囲に適用すると、数式の参照セルが空白になっている間、結果はゼロとして表示されます。 しかし、この場合、参照セルにデータが入力されるまで数式を適用するときにセルを空のままにしておきたいのですが、それを処理するためのトリックがありますか？

実際には、参照セルにデータが入力されるまで数式セルを空に保つのに役立つ数式があります。

たとえば、ここでは、[差]列の値1列と値2列の差を計算し、値1列と値2列に空白のセルがある場合はセルを空白のままにします。

計算結果を配置する最初のセルを選択し、この数式を入力します = IF（OR（ISBLANK（A2）、ISBLANK（B2））、 ""、A2-B2）、および塗りつぶしハンドルを下にドラッグして、この数式を必要なセルに適用します。
ドキュメントは2まで空白のままにします

数式では、A2とB2は適用する数式の参照セルであり、A2-B2は使用する計算です。

Hi, Carmen,try this formula: =IF(OR(ISBLANK(B2),ISBLANK(C2)), "",B2/C2), it will keep blank until both of column C and column B are filled data.

Hi, thank you much appreciated but I am still getting an error.

" There's a problem with the formula

Not trying to type a formula?
When the first character is an equal ("=") or a minus ("-") sign, Excel thinks its a formula:
you type: =1+1 the cell shows 2

To get around this try to type an apostrophe first:
'=1+1 the cell shows =1+1

I copied your code and replaced the column numbers.

Hi there, I want to create an epidemiologic formula to calculate the incidence proportion, which is the number of new cases during a specified time period / the number of people at risk. So essentially, column B divided by column C. However, I am creating the document for students of mine for their exam, so they can just type in the values and get the answer. I tried the formula you provided above =IF(OR(ISBLANK(A2),ISBLANK(B2)), "", A2-B2) but I keep getting an error. Can anyone assist?

Thanks.

Olá pessoal, parabéns pelo site, tem me ajudado bastante, segue abaixo um problema que ainda não consegui resolver, são várias situações em uma formula, segue descrição do que preciso e dados para criar o ambiente para que possa validar e quem sabe me ajudar com essa função:

Objetivo: fazer com que o Excel atualize a data de vencimento do contrato, somando a quantidade de meses da vigência, caso a renovação automática esteja "SIM" e se tiver "NÂO" ele não somará, assim um contrato que foi assinado em janeiro de 2021 e já teve sua renovação automática de 12 meses aplicada deve ter a data de vencimento atualizada para janeiro de 2023, se tivermos visualizando a planilha a partir de fevereiro de 2022, como seria essa formula?
Atualmente essa célula D1 já tem a seguinte formula que deve permanecer:
=SE(OU(ÉCÉL.VAZIA(A1);ÉCÉL.VAZIA(B1));"";(DATAM(A1;B1)))
Essa formula além de somar a data de assinatura do contrato e a vigência ela só apresenta o resultado se houver informações nas células A1 e B1, se não deixa vazia

Celular Formato Conteúdo Descrição
A1 Data Abreviada 12/11/2020 Dt Assinatura contrato
B1 Geral 12 Vigência (Meses)
C1 Geral Sim ou Não Renovação Automática
D1 Data Abreviada Formula Data Termino Contrato

Hi, Andre Oliveria, if cell A1 contains date and contract name, you need this formula 
=MID(A1,MIN(IFERROR(MIN(FIND({0,1,2,3,4,5,6,7,8,9},A1&"0123456789",1)),LEN(A1)+1)),LOOKUP(1,0*MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1),ROW(INDIRECT("1:"&LEN(A1)))) + 1 - MIN(IFERROR(MIN(FIND({0,1,2,3,4,5,6,7,8,9},A1&"0123456789",1)),LEN(A1)+1)))
to extract the date only, then use below formula 
=IF(OR(ISBLANK(B1),ISBLANK(C1)),"",IF(EDATE(B1,C1)<=NOW(),EDATE(B1,C1+1), IF(LOWER(D1)="yes", EDATE(B1,C1*2+1), EDATE(B1,C1+1))))
to get the final date.
B1 is the extracted start date, C1 is the months, D1 is "yes"or"no".

B1 Geral 12 Vigência (Meses)
C1 Geral Sim ou Não Renovação Automática

I have created simple ss to calculated days from a set date in this case E2 with G2 = E2 +30

How do I hide the result in G2 until a date is entered into E2?

Is there a standard way of doing this in excel for multiple cells at one time?

Hi, HAMISH, take A1 is the cell used to enter date, C1 is the cell that used to add 30, now in cell C1, type the formula =IF(ISBLANK(A1), "", A1+30), then the result in C1 will be shown date + 30 if a date entered in cell A1, otherwise, it keep blank. Please see the gif attached below.
