Excel Facts

Return population for a City
If you have a list of cities in A2:A100, use Data, Geography. Then =A2.Population and copy down.
Try

Dates, numbers not text, in columns A:B as dd/mm/yyyy
Months, numbers not text, in E2:E13
Some abbreviations of the months in Portuguese are different from English but very similar (fev instead of feb, abr instead of apr, etc...)
