Contenate 同时保持前导零

Question

I have an Excel spreadsheet in which the date of certain events is stored in three columns: year, month, and day.

Year	Month	Day
1734	04	08
1750	11	10

I set the format of the cell to 'custom' so as to show the leading '0' which I want to maintain. I now want to concatenate the information in these cells so that it shows the date as follows YYYY-MM-DD. I'm using this formulate to achieve that:

=CONCAT(B2, "-", C2, "-", D2)

Annoyingly, however, it doesn't maintain the leading zero (the result is: 1734-4-8 and 1750-11-10, respectively). Does anyone know how to concatenate the data from these cells while maintaining the leading zero?

Answer 1

Cell formatting only changes appearance, but doesn't alter value. Even if it looks like 04 it still is 4 as value.

Use TEXT :

=CONCAT(B2,"-",TEXT(C2,"00"),"-",TEXT(D2,"00"))

or

=TEXTJOIN("-",,B2,TEXT(C2,"00"),TEXT(D2,"00"))
