formating number with place holder

[Royce]

I have numbers on sheet some single digit and some 2-digit. I am trying to
autoformat so that all the single digit have a 0 precursor.

Ex.

1 would yield 01
but
12 would only yield 12

Format as 00

Hi

Format>Cells>Number>Custom>00

 

[Bob Phillips]

Just use a custom format of "00" (without quotes)
