MS Excel Look Up Formulaes

VLOOKUP Perhaps one of Excels most commonly used Excel Formulas is the VLOOKUP. It is also possibly the Excel formula that most people have problems understanding.
Excel HLOOKUP Another one of Excels most commonly needed Excel Formulas is the HLOOKUP.
Left Lookup in Excel Excel is very rich in Lookup formulas, with perhaps the VLOOKUP being the most popular. However, the draw-back with all Excel's Lookup formulas is that they will only look in the left most column and return the result from the corresponding cell to the right. There are times when users need to lookup data in any column of table and return the corresponding cell to the left.
Excel Lookups With Array Constants Would like to show you what I call: In-Cell-Lookups. These are the perfect replacement for multiple nested IF functions.
Dynamic Formulas Rather than bog you Spreadsheet down with hundreds, if not thousands of formulas, use a single formula with flexible and changeable Arguments. In this example I will use the INDEX/MATCH functions nested together. You can also instruct the end formula to return the corresponding cell, to the match, on the left or right.  However, the the same principles can apply to most Excel formulas.
INDEX/MATCH Functions While the Vlookup Function is very useful, it cannot look in any Column, only the 1st. Also, it cannot offset x columns to the left or return the value x rows before or after the found value. An INDEX & MATCH combo will allow for all of this flexibility.As you may already know, we can use VLOOKUP, or INDEX/MATCH to locate the first occurrence of a specified value in a list, or table of data. However, Excel has no ready made formula that allows us to locate say the second, or third occurrence etc of a specified value.
Excel Lookup Table VLookup is the perfect Excel formula for numerical values contained in a range. However if you tried to use VLookup with text in a table, it's use would be limited, For example surnames such as Smith, Smithson, Smithy, Smithson-Jacobs would create problems.
Dynamic Excel Lookups These are very handy for when you lookup data but cannot be sure which column your returned data should come from. In other words, users may have inserted a column within the table.
Lookup & Return Corresponding Result While we can use any of the links above for lookup formulas, all require a table of cells in a Worksheet. If you only have small number of items to return based on the value of another cell, we can do the lookup without leaving the cell!
Excel Hyperlinks How to get the most from hyperlinks. Hyperlinks that still work when a Worksheet name changes. Create a hyperlink to a Chart Sheet
Hyperlink to Lookup Result Excel is quite rich in Lookup type formulas, some of the more popular ones are VLOOKUP , INDEX/MATCH and HLOOKUP . These all do a great job in looking up a value we specify and then return a corresponding result. However, it's often the case that we need to go to the row containing the found value, or its offset return.
Dynamic Reports Here you can see how we can the Database functions to produce dynamic reporting from a table of data.
Multi-Table Lookup Use the Dependent Validation Lists method to tell Excel to lookup any chosen item in any table you tell it.
