vlookup - looks up a table by the left hand column:
eg. a table:
__| A | B | C
1 | a | 7 |
2 | b | 8 |
3 | c | 9 |
(the 1st row and 1st column (A, B, C) and (1, 2, 3) are column letters and row numbers in excel)
=vlookup("a", a1:b3, 2)
will give the answer 7 (looks at the left hand column of a1:b3, look for the letter "a", and give the value of the cell in the 2nd column.
A more detailed explanation is:
=vlookup(the value to find on the left hand column, where the table is, the column number from the left to retrieve the answer, whether the closest match would do [true/false]) - The last part is optional.
pivot table allows you to aggregate (produce a summary of) the data.
a simple example:
fruit | price
apple | 1.20
apple | 1.40
orange | 5.00
orange | 4.00
by making a pivot table, you can make excel calculate automatically:
fruit | average price | min price | max price
apple | 1.30 | 1.20 | 1.40
orange | 4.50 | 4.00 | 5.00
To create a pivot table, Excel provides a wizard to guide you through the process and I will not elaborate more (I can't put a screen shot or anything like that yet).
Both functions are available since Excel 5.0 (the version before Excel95. Excel 2000 is version 9.0).
There is a function call a cross tab table in Excel 4.0, which is similar to the pivot table.
