+What is Lookup?

In Excel, the Lookup function returns a value from a range (one row or one column) or from an array.

Lookup is the simple function to return the value from a specific range.

This function looks for a piece of information in a list, and then picks an item from a second range of cells.

=LOOKUP(WhatToLookFor,RangeToLookIn,RangeToPickFrom)

The WhatToLookFor should be a single item.

The RangeToLook in can be either horizontal or vertical.

The RangeToPickFrom must have the same number of cells in it as the RangeToLookin.

Be careful not to include unnecessary heading in the ranges as these will cause errors.

+What is lookup (Array)? This function looks for a piece of information in a list,

+ What is Vlookup?

This function scans down the row headings at the side of a table to find a specified item.

When the item is found, it then scans across to pick a cell entry.

'=VLOOKUP(ItemToFind,RangeToLookIn,ColumnToPickFrom,SortedOrUnsorted)

The ItemToFind is a single item specified by the user.

The RangeToLookIn is the range of data with the row headings at the left hand side.

The ColumnToPickFrom is how far across the table the function should look to pick from.

The Sorted/Unsorted is whether the column headings are sorted. TRUE for yes, FALSE for no.

+What is Hlookup?

This function scans across the column headings at the top of a table to find a specified item. When the item is found, it then scans down the column to pick a cell entry.

The ItemToFind is a single item specified by the user.

The RangeToLookIn is the range of data with the column headings at the top.

The RowToPickFrom is how far down the column the function should look to pick from.

The Sorted/Unsorted is whether the column headings are sorted. TRUE (or 1) for yes, FALSE (or 0) for no.
