I inherited an excel spreadsheet that contains a lot of data. All the
numbers in this spreadsheet are formatted in the millions. (ex: 6,000,000) I
would like to change the formatting of the numbers to just display the 6 as
opposed to showing commas and decimal places. I have tried the decrease
decimal, but that did not work. I tried the round formula, the Rounddown
formula, and the Mround formula, but I cant get them to just display the
first digit.

Is there a way to tell Excel to drop all commas, and decimal places in large
numbers?

Thanks, :)
