There are Detailed LET function example. The goal is to generate a custom message for any name in the list by entering a valid ID in cell G5. The message uses the name The goal in this example is to create a self-contained lookup formula to assign a grade to the score in cell E7, based on the table in B6:C The lookup table is the named range "key" B5:C9. It is often a useful error, because it tells you something important is missing — a product not yet available, an employee name Income tax bracket calculation.
Map inputs to arbitrary values. This formula uses the value in cell F6 for a lookup value, the range B5:C10 for the lookup table, 2 to indicate "2nd column", and zero as the last argument to force an exact match. Although in this case we are mapping Abbreviate state names.
This formula relies on a table with columns for both the full state name and the 2-letter abbreviation. For simplicity, the table has been named Because it is a numeric value, you can just enter the number. But if the search value was text, you would need to put it in double quotes, for example:.
In this example, the second parameter is A1:B6 which gives us two columns to data to use in the vertical lookup - A1:A6 and B1:B6. The first column in the range A1:A6 is used to search for the Order value of The second column in the range B1:B6 contains the value to return which is the Product value. The third parameter is the position number in the table where the return data can be found.
A value of 1 indicates the first column in the table. The second column is 2, and so on. In this example, the third parameter is 2. This means that the second column in the table is where we will find the value to return. Since the table range is set to A1:B6, the return value will be in the second column somewhere in the range B1:B6. If you like, you can adjust the VLOOKUP formula to use a built-in wildcard, like the example below, where we simply concatenate the value in H3 with an asterisk.
They give you an easy way to create a "lazy match", but they also make it easy to find the wrong match. In one way, this is useful because it tell you definitively that there is no match in the lookup table. To trap this error and display a "not found" message instead of the error, you can simply wrap the orignal formula inside of IFERROR and set the result you want:. Here is the formula:. If you are simply retrieving numbers as text from a column in a table, it doesn't matter.
In the following example, the ids for the planet table are numbers entered as text , which causes VLOOKUP to return an error since the lookup value is the number To solve this problem, you need to make sure the lookup value and the first column of the table are both the same data type either both numbers or both text. One way to do this is to convert the values in the lookup column to numbers.
An easy way to do this is to add zero using paste special. If you don't have easy control over the source table, you can also adjust the VLOOKUP formula to convert the lookup value to text by concatenating "" to the value like so:. If you've ever built a series of nested IFs, you know that they work fine, but they require a bit of parentheses wrangling.
You also have to be careful about the order you work in, so as not to introduce a logical error. For example, a common use of nested IFs is to assign grades based on a score of some kind. In the example below, you can see a formula has been build with nested IFs to do just that, using the grade key at the right as the guide.
This works fine, but note that both the logic and the actual scores are baked right into the formula. If the scoring changes for any reason, you'll need to carefully update one formula then copy it down the entire table. A nice bonus of this approach is that both the logic and the scores are built right into the grade key table. If anything changes, you can simply update the table directly and the VLOOKUP formulas will update automatically - no editing required.
By design, VLOOKUP can only find values based on a single criteria, which is supplied as a lookup value to find in the first column of the table the lookup column.
This means you can't easily do things like look up an employee with the last name of "Smith" in "Accounting", or look up an employee based on first and last names in separate columns. However, there are ways overcome this limitation. One workaround is to create a helper column that concatenates values from different columns to create lookup values that behave like multiple conditions.
