Do you want to change the thousands separator from '.' to ','? Or do you want to truncate the value 1235000 -> 1200000? – Daisetsu Feb 10 '11 at 0:16

Excel doesn't support rounding to significant digits as a number format, you have to calculate it using formulas: ROUND, ROUNDUP, and ROUNDDOWN mainly.

e.g. =ROUND(A1,1-INT(LOG10(ABS(A1)))) will round A1 to 2 significant digits

e.g.2 =ROUND(A1,A2-1-INT(LOG10(ABS(A1)))) will round A1 to A2 significant digits

I'm not sure what you're asking here. I've adjusted the answer so it's more general and will round to any number of significant digits. If you are asking about commas and decimal places once you've rounded, then you just use normal cell formatting to achieve that. – Rhys Gibson Feb 13 '11 at 7:34
