为什么 INDEX/MATCH 打印 0 而不是我在 EXCEL 中所期望的

Question

I just started using INDEX/MATCH function in Excel and have no idea why it is printing only 0

=INDEX(DATA!$B:$B, MATCH(index!$C3, DATA!$A:$A,0))

So Im using the expression above and have no trouble with the result.

However when I try to print the column with Korean (DATA:$C:$C) it shows only 0

other than C column it has no problem printing out:( ($D:$D, $E:$E,... and so on has no problem)

When the value returned by INDEX is blank, Excel often interprets it as a number (0).

There are a number of ways to rectify it. If you want the result to always be a string, you can simply add an empty string onto the end of the result:

 =INDEX(DATA!$B:$B, MATCH(index!$C3, DATA!$A:$A,0)) & ""

If you are not sure if it will return a number or a string, you can wrap your formula in an IF to force blanks to return as an empty string instead of a number:

=IF(
    INDEX(DATA!$B:$B, MATCH(index!$C3, DATA!$A:$A,0))="",
    "",
    INDEX(DATA!$B:$B, MATCH(index!$C3, DATA!$A:$A,0))
)
