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

I've found the following combination that works fine for positive and negative numbers (43787200020 is transformed to 43.787.200,02 K)

[>=1000] #.##0,#0. "K";#.##0,#0. "K"
