Format numbers in thousands (K) in Excel

Question

In MS Excel, I would like to format a number in order to show only thousands and with \'K\' in from of it, so the number 123000 will be displayed in the cell as 123K

Answer 1

Enter this in the custom number format field:

[>=1000]#,##0,"K€";0"€"

What that means is that if the number is greater than 1,000, display at least one digit (indicated by the zero), but no digits after the thousands place, indicated by nothing coming after the comma. Then you follow the whole thing with the string "K".

Edited to add comma and euro.
